McCormack,E. D. WA-RD 607.1 Options for Benchmarking Performance Improvements Achieved from Construction of Freight Mobility Projects 2005 TRAC/UW
Abstract:
This report documents the development of data collection methodologies that can be used to cost effectively measure truck movements along specific roadway corridors selected by transportation agencies in Washington State. The intent of this study was to design and test methodologies that could be used to measure the performance of freight mobility roadway improvement projects against benchmarks, or selected standards, that would be used both as part of the project selection process and to report on speed and volume improvements that resulted from completed freight mobility projects. One technology tested was Commercial Vehicle Information System and Networks (CVISN) electronic truck transponders, which are mounted on the windshields of approximately 20,000 trucks in Washington. By using software to link the transponder reads from sites anywhere in the state, the transponder-equipped trucks could become a travel-time probe fleet. The second technology tested involved global positioning systems (GPS) placed in volunteer trucks to collect specific truck movement data at 5-second intervals. With GPS data it was possible to understand when and where the monitored trucks experienced congestion and to generate useful performance statistics. The study found that both data collection technologies could be useful; however, the key to both technologies is whether enough instrumented vehicles pass over the roadways for which data are required. This basic condition affects whether the technologies will be effective at collecting the data required for any given benchmark project. The report also recommends the traffic data that should be collected for a benchmark program and the potential costs of using either data collection technology.

Hieber,D. G. WA-RD 611.1 Precast Concrete Pier Systems for Rapid Construction of Bridges in Seismic Regions 2005 TRAC/UW
Abstract:
Increasing traffic volumes and a deteriorating transportation infrastructure have stimulated the development of new systems and methods to accelerate the construction of highway bridges. Precast concrete bridge components offer a potential alternative to conventional reinforced, cast-in-place concrete components. The use of precast components has the potential to minimize traffic disruptions, improve work zone safety, reduce environmental impacts, improve constructability, increase quality, and lower life-cycle costs. This study compared two precast concrete bridge pier systems for rapid construction of bridges in seismic regions. One was a reinforced concrete system, in which mild steel deformed bars connect the precast concrete components and provide the flexural strength of the columns. The other was a hybrid system, which uses a combination of unbonded post-tensioning and mild steel deformed bars to make the connections. A parametric study of the two types of systems was conducted using nonlinear finite element models to investigate the global response and likelihood of damage for various frame configurations. On the basis of this study, a practical method was developed to estimate maximum seismic displacements from the cracked section properties of the columns, the elastic design displacement response spectrum, and the base-shear strength ratio. The results of the global nonlinear finite element analyses suggest that the systems have the potential for good seismic performance. Further analytical and experimental research is needed to investigate the constructability and seismic performance of the connection details.

Al-Yagout, M.A. WA-RD 600.1 Improving Traffic Characterization to Enhance Pavement Design and Performance: Load Spectra Development 2005 TRAC/UW
Abstract:
This research addresses the understanding of, and need for, load spectra in future pavement design procedures and as a stepping stone toward more complete pavement design. The primary objective of this project was to develop truck axle load spectra for Washington State. To do this, axle load data collected at WIM stations throughout Washington State were used. The developed load spectra encompass the principal truck axles on the roadway network: single, tandem, and tridem. Achieving this objective allows the Washington State Department of Transportation, or any state highway agency with analogous traffic patterns, to accommodate the requirements of the 2002 Design Guide, developed through NCHRP Project 1-37A. A secondary objective of this project was to determine whether ESALs obtained from the developed load spectra are significantly different from historical values. Because the developed load spectra are transformable to ESALs, state highway agencies that decide not to use the new guide can still choose to employ the ESALs produced with the load spectra. The project concluded that the developed load spectra are reasonable. For single axles they are comparable to the 2002 Design Guide and MnROAD defaults. For tandem and tridem axles, they are slightly more conservative than defaults of the 2002 Design Guide and MnROAD, but they are still within reason. In addition, the ESALs per vehicle class associated with the developed load spectra are comparable to Washington State historical ESALs for vehicle classes 9, 10, and 13. The use of the newly developed ESALs per vehicle will generally increase design ESALs, but that increase will be due to inclusion of the less predominant vehicle classes (4, 6, 7, 8, and 11).

McCormack,E. D. Options for Benchmarking Performance Improvements Achieved from Construction of Freight Mobility Strategic Investment Bo... 2004 TRAC/UW
Abstract:
This report documents the development of data collection methodologies that can be used to cost effectively measure truck movements along specific roadway corridors selected by the Freight Mobility Strategic Investment Board (FMSIB.) The intent of this study was to design and test methodologies that could be used to measure the performance of freight mobility roadway improvement projects against benchmarks, or selected standards, which would be used both as part of the project selection process and to report on speed and volume improvements that resulted from completed FMSIB projects. One technology tested was Commercial Vehicle Information System and Networks (CVISN) electronic truck transponders, which are mounted on the windshields of approximately 20,000 trucks traveling in Washington. These transponders are used at weigh stations across the state to improve the efficiency of truck regulatory compliance checks. By using software to link the transponder reads from sites anywhere in the state, the transponder-equipped trucks could become a travel time probe fleet. The second technology tested involved global positioning systems (GPS) placed in volunteer trucks recruited for this project to collect specific truck movement data at 5-second intervals. With GPS data it was possible to understand when and where the monitored trucks experienced congestion. By aggregating this information over time, it was possible to generate performance statistics related to the reliability of truck trips, and even examine changes in route choice for trips between high volume origin/destination pairs. The study found that both data collection technologies could be useful; however, the key to both technologies is whether enough instrumented vehicles pass over the roadways for which data are required. This basic condition significantly affects whether the transponder and GPS technologies will be effective at collecting the data required for any given FMSIB benchmark project . The report also recommends the traffic data that should be collected for a benchmark program and the potential costs of using either data collection technology.

Li, J. WA-RD 588.1 Application of HDM-4 in the WSDOT Highway System 2004 TRAC/UW
Abstract:
This project performed extensive study and systematic research on the application of the Highway Development and Management system (HDM-4) to the Washington State Department of Transportation (WSDOT) highway system. Data processing, testing, calibration, and analysis were executed to provide the WSDOT with a new budget planning tool. HDM-4 flexible pavement deterioration models were calibrated with the assistance of the Washington State Pavement Management System. A method to calibrate concrete pavement distress models is proposed. This research also explored the application of HDM-4 analysis at the project, program, and strategic levels. The applications include prediction of pavement conditions during a defined analysis period, calculation of required budgets for optimal pavement conditions and maximum economic indicators, establishment of optimized work programs under varying levels of constrained budgets, and other applications for WSDOT.

Moudon,A. V. WA-RD 574.1 Strategies and Tools to Implement Transportation-Efficient Development: A Reference Manual. Phase 2 of Integrating Land ... 2003 TRAC/UW
Abstract:
This Reference Manual addresses land use and development practices that support and improve the efficiency and effectiveness of associated transportation systems. It references strategies and tools used to foster transportation-efficient land-use patterns (transportation-efficient development is defined as supporting the use of alternative transportation modes while reducing the need to drive alone). The manual documents state-of-the-art best practices at the national level, in addition to practices that are specific to Washington State and the Puget Sound region.The Manual is in two parts: regulatory strategies and tools and financial strategies and tools. The strategies (six regulatory and four financial) relate to the planning and policy-making environment shaping land use those general approaches and related policies used to plan transportation-efficient land use and development. Each strategy in turn contains a number of tools, the specific mechanisms used to guide the implementation of the strategies. Detailed explanations of how the tools have functioned or can work are provided, along with examples of specific applications and case studies to illustrate the scope and extent of the tools' effectiveness.The Reference Manual is the second product of a three-phase project by the Washington State Department of Transportation, which is known as Integrating Land Use and Transportation Investment Decision-Making. The first phase reviewed current land-use and development practices by the various local jurisdictions. It is summarized in Implementing Transportation-Efficient Development: A Local Interview (WSDOT 2002, WA-RD 549.1). The third phase will integrate findings from phases 1 and 2 with other data to produce criteria for evaluating the transportation efficiency of land-use and development patterns. It will provide WSDOT with a method to assess how existing and planned land uses could extend, support, or shorten the lifespan of existing or planned transportation system capacity.

Ishimaru,J. M. WA-RD 555.1 North Seattle Advanced Traffic Management System (NSATMS) Project Evaluation 2002 TRAC/UW
Abstract:
This report documents the findings of the evaluation of the North Seattle Advanced Traffic Management System (NSATMS) Project. The evaluation was originally designed to analyze the potential transportation benefits and costs of a regional arterial traffic data sharing system that would obtain traffic signal system information (volumes, signal timing plans, etc.) from participating agencies and then share the data among those agencies. The operational goal was to allow each agency to make better control decisions by providing it with real-time knowledge of traffic conditions outside of its own control system boundaries. Because of a series of technical and project management issues, the system as originally envisioned was not successfully implemented. As a result, this evaluation does not include an analysis of direct operational benefits. It does, however, include a discussion of the expected institutional benefits, as well as an extensive "lessons learned" section based on the project team's review of the NSATMS effort. Of particular note were the importance of effective and ongoing lines of project communication, and the critical need to properly evaluate the fundamental nature of the project and provide a well-matched project management structure. The lessons learned from this project provide instructive guidelines for those who are contemplating future ITS system development efforts of comparable scope and complexity. Despite the limited successes of the NSATMS effort, the evaluation team found continued support for the regional arterial ATMS concept within the Puget Sound region. Follow-on research that contributes to a better understanding of the benefits, costs, and technical requirements of an arterial traffic management system is desired by many of the project participants.

Wetherby,B. WA-RD 462.4 SWIFT - Institutional Issues 1998
Abstract:
The Seattle Wide-area Information for Travelers (SWIFT) project was a highly successful Intelligent Transportation System (ITS) Field Operational Test (FOT) that was conducted over a four-year period from 1993 to 1997. The purpose of the project was to test the efficacy of a High Speed Data System (HSDS), or FM Sub-carrier, to disseminate incident, bus and speed congestion information via three different end-user devices: pager watch, portable computer and in-vehicle navigation device. Six hundred ninety (690) commuters, many with route- or mode-choice options, participated in the FOT and provided user-acceptance evaluations. Other evaluation components examined the system architecture, communications coverage, deployment cost and institutional issues that affected the project.The primary purpose of the SWIFT Institutional Issues Study evaluation was to collect information regarding the institutional issues (e.g., policies, jurisdictional issues, internal and external factors) that affected design, development, testing, deployment and conduct of the SWIFT Field Operational Test (FOT); determine how these issues were overcome and what lessons could be learned. A secondary purpose of the evaluation was to document the history of the SWIFT project.The methodology for the SWIFT Institutional Issues Study consisted of two sets of questionnairesand two sets of semi-structured interviews that were conducted with fourteen (14) SWIFT team memberrepresentatives at two different points during the conduct of the SWIFT FOT: about midway through the conduct of the test and after the test was completed. All SWIFT team member responses were independently collected and SWIFT institutional issues were primarily identified by determining which topics were addressed by two or more individuals. Historical information was collected from various sources throughout the project.SWIFT represents one of the first ATIS FOTs conducted in this country. Earlier tests were conducted in Orlando, FL (TravTek) and Minneapolis St. Paul (Genesis) among others, yet the SWIFT FOT appears to have extended considerably the available database of information regarding ATIS effectiveness and acceptance. The addition of real-time bus information, in particular, has set the SWIFT FOT apart from others already conducted.One of the significant aspects of the SWIFT teaming agreement was the long-term interest in ITS and commitment of the organizations involved. For instance, the majority of the SWIFT team members articulated a long-term interest in ITS deployments. In addition, three organizations-Seiko, Etak and Metro Traffic Control-+ommitted themselves to fielding a \"SWIFT-like\" system after the project was completed. This degree of interest and commitment resulted in all of the SWIFT team members working together in a very effective, cooperative fashion throughout the FOT.A critical organizational structure that was instituted to implement SWIFT was the weeklyteleconference. This simple, yet cost-effective method of managing and discussing the technicalissues involved with the project was attributed by many of the SWIFT team members to aprimary instrument of the project\'s success. In particular, the SWIFT teleconferences enabledthe representatives of each organization to keep abreast of the developmental status of theproject, to brainstorm solutions to encountered problems and to develop scheduling sense.

Other evaluation components examined the system architecture, communications coverage, institutional issues, and consumer acceptance. The primary purpose of the SWIFT Deployment Cost Study was to provide an independent Life Cycle Cost Estimate (LCCE) of an operational and fully deployed SWIFT system. Moreover, it is intended to provide both the SWIFT participants and the FHWA with a measure of the commercial viability of \"SWIFT-like\" systems nationwide.

Davids, W.G. WA-RD 455.1 Modeling of Rigid pavements: Joint Shear Transfer Mechanisms and Finite Element Solution Strategies 1998 TRAC/UW
Abstract:
This report documents the moldeling strategy and associated verification which permits analysis of multiple PCC plain jointed slabs. Several subbase/soil layers below the slabs and separation of the slab and base layer are considered. Load effects include those associated with both multiple tire and linear temperature gradients. A technique for modeling aggregate interlock shear transfer across PCC pavement joints is developed and verified. The overall development is contained in the computer program EverFE. The computer program uses a graphical user interface which aids its use.

Hoel, R. IU 95.5 Joint Development at Park-and-Ride Lots: An Assessment of Services and Amenities 1995 Innovations Unit/TRAC
Abstract:
Joint development of park-and-ride lots involves a public-private partnership between businesses, transit agencies, and local governments. Such an arrangement consolidates retail services into a single area and, thus, has the potential to improve individual park-and-ride facilities and transit system networks. New retail stores on the premises can add to the attractiveness of parking lots. The attraction of new capital funding sources and increased transit ridership may encourage transit operators and transportation policy-makers to support join development. This report examines several issues surrounding joint development at park-and-ride lots. First, joint development may benefit commuters, surrounding residential areas, and government agencies. Second, security concerns are a barrier to higher park-and-ride patronage, but joint development and other design techniques can improve personal and vehicle safety. Third, the results of a market feasibility study of convenience services at park-and-ride lots are examined to understand the range of potential services possible through joint development. Fourth, the results of a survey of park-and-ride patrons at three Puget Sound area facilities are considered. The survey was conducted to learn about park-and-ride lot users\' attitudes toward the facilities, the quality of services currently offered, the elements users consider important, and the goods and services users would like available.

Zemotel,L. IU 93.6 Travel Patterns in Mixed Use Neighborhoods: Phase I 1993 Innovations Unit/TRAC
Abstract:
This working paper, \'Travel Patterns in Mixed Use Neighborhoods,\' summarizes Phase I of a research effort by the Innovations Unit of the Washington State Transportation Commission. The study is based on previous Innovations Unit research, described in the 1992 report, Land Use-Transportation Linkage (Kestle et al. 1992), the focus of which was the impact of land use policies on transportation systems. This working paper describes surveys conducted in four neighborhoods in the state of Washington (three in King County and one in Spokane) to gather data on travel behavior in neighborhoods that have a good mix of housing, shopping, and services; in other words, mixed use neighborhoods. The survey consisted of telephone interviews to determine household characteristics and the subsequent collection of travel diaries to assess household travel habits by mode and purpose. Preliminary results indicate the preponderance of trips for both family and personal business on both weekdays and weekends. Although auto is the dominant mode, results indicate the potential for shared rides in all neighborhoods and for the walk mode in the in-city neighborhoods. Directions for future research are suggested, including the study of the potential for reducing vehicle miles traveled (VMT) in mixed use neighborhoods; the relationships among mixed use development, household demographics, and travel behavior; the possibility of substituting walking for auto use; and methods for alleviating weekend traffic congestion based on a better understanding of the components of weekend travel.

Herman,L. A. WA-RD 327.1 Noise Mitigation Strategies - Final 454 1993
Abstract:
Noise mitigation strategies involving both noise reduction at the source of transportation noise and at the receiver of transportation noise are reviewed. The following major sources of noise within a motor vehicle considered: engine, intake, exhaust, cooling fan, transmission, and tire noise. Current research intended to address methods of reducing noise far each of these sources is discussed. It was found that vehicle manufacturer efforts in the U.S. to reduce vehicle noise is currently being motivated marketplace for quiet vehicles. In addition to the potentialnoise reduction from specific components of the vehicle, it was found that the type of roadway pavement can have a significant effect on noise. A key strategy for reducing transportation noise at the receiver of the noise is land use compatibility planning. local agencies who have successfully implemented and use compatibility planning programs were interviewed. These programs fall into two broad The first category is land use compatibility brought about by zoning. this category, land uses that are inherently with transportation noise sources are adjacent to the sources. The second category, referred to as proponent mi involves a process of mitigation needed to make the use with transportation noise through mitigation efforts funded by the proponent of the development. It was found that noise and land use compatibility programs were most beneficial to communities in the earlier stages of development whereas the use of a local noise ordinance was found to be more beneficial to communities that are more fully developed.

Carney III,J. F. WA-RD 308.1 Development of Maintenance-Free Safety Appurtenances 1992
Abstract:
This final report demonstrates the feasibility of employing high molecular weight/high density polyethylene cylinders as the energy dissipating medium in highway safety appurtenances. It is shown that this polymer can dissipate large amounts of kinetic energy, undergo large deformations and strains without fracturing, and essentially restore itself to its original size, shape, and energy dissipation potential when the forcing function is removed.This research involves a quasi-static and impact loading experimentalinvestigation to determine the energy dissipation characteristics of HMW HDPEtubes as functions of temperature, radius to wall thickness ratio, strain,strain-rate, deformation, and repeated and cyclic loading. The results ofthis experimental program are analyzed to develop analytic energy dissipationexpressions which are then employed in the design of truck mountedattenuators (TMA), Finally, an expert system computer program, CADS, ismodified to use HMW HDPE tubes in the generalized design of crash cushions.The potential financial, legal, and safety payoffs for highway operationsassociated with developing highway safety devices which are essentiallymaintenance free are significant. Maintenance costs associated with therepair of impacted safety devices would be greatly reduced or eliminated.Tort liability exposure related to damaged or collapsed hardware would besignificantly decreased. Finally, the safety of the motoring public and themaintenance personnel involved in maintaining and repairing damaged hardwarewould be enhanced.

Sorensen,H. WA-RD 166.1 Bridge Standards - Local Governments 1988
Abstract:
In this study a survey was conducted to ascertain the needs of employees of local governmental agencies with regard to the conduct of the design of bridges. Recommendations, relative to the development of standard plans which can be used by county engineers, are put forth. These recommendations are based on the needs of the local agencies, information regarding existing manufacturing capabilities, information concerning existing standard plans relative to bridges and information on an existing computer software program (BRADD-2) which is available from the AASHTO. The information on which the recommendations were made was obtained by telephone conversations, written questionnaires and/or personal visits with/form/to 75 local agencies (46 cities and 39 counties) in the state of Washington and by personal visits to 4 precasitng plants and 1 fabricating plant.

Ernst,D. D. WA-RD 113.1 Alternative Deicing (CMA Research) 1988
Abstract:
As part of the pooled fund research project, the Washington State Department of Transportation was selected to field-test approximately 100 tons of Calcium Magnesium Acetate (CMA) to evaluate its potential as a deicing chemical with direct comparison to salt (Sodium Chloride) and Urea. Evaluation included all aspects of storage, handling, use, and performance. CMA was applied whenever necessary at each test site, using the same application rates as presently used for salt. Typical equipment consisted of front dump trucks with the spinner ahead of the rear axle, and rear discharge hopper trucks. All equipment was used without modification.The use of CMA at the beginning of a storm reduced the amount of bonding of snow to the roadway surface. This effect of keeping the roadway surface bare for longer periods of time reduced the cost of snow fighting. This was accomplished with chemical application rate of 125 Ibs. per lane mile.The addition of sand to CMA reduced the problems of dust, caking and uneven distribution. The sand provided moisture and weight to the application resulting in a smoother, more even distribution. CMA spread above was excessively dusty creating problems in the spreading and distribution. CMA is slower to react on compact snow and ice than salt or Urea. This delay in reaction time was not considered a handicap in the overall snow fighting procedure.The conclusion was that CMA shows promise as a deicing-melting chemical. The problems of dust, light-weight and brittleness need further work and may be significantly alleviated by development of a hydrated compound.

Ritchie,S. G. WA-RD 083.1 Statewide Highway Data Rationalization Study 1986
Abstract:
This study involved an in-depth evaluation of the Washington State Department of Transportation highway data development and analysis activities. It developed statistically-based procedures and recommendations for a streamlined highway data collection program. Opportunities to reduce manpower and equipment costs, streamline work activities, improve the quality of data collection and provide accurate and timely data for the various users were identified. Given the focus on highway data, the major effort was devoted to the Department's traffic counting program. However, many data items and programs were considered, with the following receiving particular attention: traffic volume counting, including estimation of annual average daily traffic at any location throughout the state highway system; associated seasonal, axle and growth factors; vehicle classification; truck weights; and the relationship between the statistical sampling requirements recommended for these items and those associated with the FHWA Highway Performance Monitoring System in the state.

Higgins,J. D. WA-RD 069.1 Development Of Guidelines For Cuts On Loess Soils 1985
Abstract:
The first phase of a three-phase research investigation of cut slope design criteria for southeastern Washington loess has been completed. A literature review of engineering properties of loess from other locales and design criteria applied by various state transportation departments were conducted. A1so, a preliminary field investigation was made to collect representative soil samples and record failure mechanisms. Past research has revealed that proper drainage control in combination with water content and gradational characteristics, are the primary factors influencing cut slope performance in loessial soils. Analysis of 40 soil samples collected during the field study, demonstrate a close similarity between southeastern Washington loess and deposits from the central United States. Although physical properties are similar, differing climates produce a disparity in failure mechanisms between Midwestern and southeastern Washington loessial deposits.

Nielsen,Robert S. WA-RD 043.1 Allocation Of Transportation Resources: Development Of An Evaluation Method 904 1982
Abstract:
The objective of this report is to develop an effective transportation resource allocation technique that is flexible and can be applied to various areas. Allocation procedures were developed and tested for apportioning resources to transportation services in relation to community transportation objectives. Procedures were developed and applied that measured the effectiveness of candidate transportation service proposals in terms of a transportation resource allocation index (TRAI). The extent to which a transportation proposal achieves the community objectives is defined as its effectiveness. The transportation index was computed on the basis of the projects scorings for eight selected determinants, multiplied by the weighing assigned to each determinant in accordance with their relative effectiveness.The TRAI for eight transportation service proposals including transit, were computed as a pilot study and as a working test of the techniques in the Tri-Cities area of Richland, Kennewick, and Pasco, WA. There appears to be no complication in implementing this technique for allocations in any local urban area providing the concepts are correctly evaluated and applied.

Abstract:
This report describes the pavement management system developed by WSDOT staff over a period of five years. Both project-level and network-level pavement management are represented within the four broad areas of data processing which combine to constitute the foundation of the system.The design of a pavement data file is laid out together with the process of assembling it. Also shown are the methods used to analyze and convert the file data from pavement condition ratings to pavement performance curves for each project. The performance curves are then used, together with appropriate cost data, to determine the most cost-effective type and time to fix. The network-level program then summarized the need work for each year of a rehabilitation program. Mean are provided for adjusting the program to fit budget constraints or minimum acceptable levels of average pavement condition.It is concluded that the system, operating on biennial pavement condition ratings, provides a good solid framework for orderly analysis to estimate the economic benefits of the type, timing, and sequence of rehabilitation activities applied to a pavement.

Social and Econonomic Planning Section of the WA State Department of Highways WA-RD 037.1A Impact Of Highway Improvement On Property Values In Washington 933 1980
Abstract:
Transportation improvements of all kinds are being evaluated more carefully than ever during the planning stages. This attention to detail is well justified because the implications of such projects transcend the engineering disciplines and have environmental, social , and economic effects of major importance. In the economic area one of the impacts that is of great concern to the public i s the effect of a highway on property values. The purpose of this study is to measure the beneficial and adverse effects of limited- access highways on property values. A need exists in the State of Washington to have current data and analyses concerning this subject that apply specifically to this state . In addition there have been several theoretical developments that allow refinement of previous studies and validation of the results .OverviewThis study analyzed the beneficial effects of a highway on the values of surrounding properties by determining the real estate price trends in areas where a highway was constructed and comparing these trends with those in comparable areas which did not experience such changes. There were four residential areas utilized for parts of this study: Kingsgate east of Lake Washington on 1-405, north King County along 1-5 north of the Seattle city limits , Spokane near the east city limits along 1-90, and the southeast section of Puyallup along SR 512. Because of the lack of an adequate control area f o r the Spokane study, only the other three areas were used for the benefit estimation.

Veress,S. A. WA-RD 031.1 Photogrammetric Monitoring Of A Gabion Wall 952 1977
Abstract:
A photogrammetric monitoring method of structural deformation has been developed during the course of this project. The Gabion Wall which is part of the I-90 project has been used as the site for practical tests of the theorectical development. The monitoring consists of photographing the structure from three camera stations with KA-2 f=24" camera. The camera has been modified to a plate camera to provide the maxium accuracy.The methodology consists of the geodetic determination of the camera location and the orientation and photogrammetric determination of targets (natural and artificial) on the structure. During the course of this project more than 100 target locations were determined by three dimensional coordinates. the maximum error was found to be + 3/4 inch; the average, 1/2 inch. This represents a relative accuracy of from 1/58,00 to 1/120,00 of the photographic distance.Using the actual construction site for research has permitted immediate implementation. The instrumentation as well as the methodology along with the computer program has been transmitted to the Washington State Highway Department and their Photogrammetric Branch has been assisted in the implementation.

Abstract:
The objective of study was to develop criteria and procedures for the identification and measurement of social in transportation planning and the process by which such analyses are integrated into the decision-making process. The guidelines developed from this address several related but different parts of the total planning and design process. Two of the reports prepared as a part of this study are concerned with identifying and measuring social factors and conducting social and economic surveys to obtain necessary data. A third report is concerned with the development and implementation of involvement programs. The is made that an effective planning and design process must provide means by which the values and of residents of affected and users of transportation facilities can be incorporated in technical studies and the decision-making process. Two additional reports contain guidelines for the operation of interdisciplinary teams and team scheduling and management. The systematic interdisciplinary approach undertaken in the State of Washington provides a means by which technical data, values and opinions, and planning and design concepts and standards can all be evaluated by the team in reaching a solution to a problem.

Abstract:
The purpose of this study is to produce guidelines that will provide assistance to those responsible for the planning and implementation of community involvement plans. These guidelines cover the many elements of a multi-faced community involvement approach and give direction for planning and implementation of these guidelines.A considerable amount of recent experience and information on community involvement was compiled and analyzed to afford the capability of tailoring a community involvement plan for an individual plan for an individual and unique community as defined by its characteristics. Among the major elements discussed are the general principals which must be followed to achieve successful community involvement; the criteria to determine how extensive an involvement plan should be for a particular community as defined by the characteristics of the community and type of proposed action; the establishment of an implementation schedule; detailed discussion of the methods used to disseminate information and obtain citizen input; a description of the various types of community groups which can be used for cooperative planning; recommendations to improve the effectiveness of public meetings; and the basic strategy used in evaluating the success of a community involvement plan.

Abstract:
The purpose of this study is to establish guidelines and procedures for the measurement of the social effects of transportation systems and facilities on both a regional and community or neighborhood level. This coincides with the increased emphasis on human factors in the planning and design of transportation systems and facilities, which has necessitated the development of a systematic approach to gathering social data and developing normative standards. In part of this increased emphasis has been mandated by Federal statutes such as the National Environmental Policy Act o f 1969 and the Intergovernmental Act of 1968.A detailed examination of the seven-fold classification scheme of social factors and an emphasis on the methodologies used to evaluate social impacts is discussed. Emphasis is placed on the analytical framework utilizing the major phases of inventing existing social conditions, identifying potential changes and measurement of probable impacts. From this analysis a systematic approach to identifying and measuring social impact in transportation planning is put forth, for use by those assigned this responsibility.

Abstract:
The purpose of this document is to present an effective method by which the scheduling and coordination of the activities of interdisciplinary teams can be carried out. A number of more traditional techniques of project control have not met the unique requirements of scheduling and managing the activities of an inter-disciplinary team since the basic logic of task ordering is time sequentiality. Quite a number of the activities of inter-disciplinary team can be carried on simultaneously or at any time within the project's period. The system developed within this document uses the principal of "nested" descriptions of program activities and then proceeds to develop operational procedures. The role of the individual team members as well a the overall project development is described.

Karlfritz,L. WA-RD 011.1 Weekend And Recreational Development Of A New Concept 1021 1971
Abstract:
The ProblemThe growth of population in metropolitan areas and the increasing affluence and leisure time of that population is exerting ever-increasing pressure on recreational resources and the transportation facilitiesconnecting the metropolitan areas with the recreation areas. Historically, travel for recreational purposes has grown more rapidly than that for other purposes and if forecasted increases in real income andleisure time materialize this trend will continue. There is increasing concern that proper attention has not been given to recreational travel as a factor in transportation planning either at the state or urban area level. Recreational travel occurs primarily on weekends and holidays whereas the urban transportation studies, almost without exception, are concerned with weekday travel. Recreational travel serves both as a means to an end and as an end in itself. Access to a variety of recreational activities is an importanthuman need and is presumed to be an agreed-upon objective of-public policy. In addition travel has an intrinsic recreational value, the extent of which depends on place and circumstances. This study proposes a concept far long-range planning of transportation facilities needed to serve the weekend travel demands of a metropolitan area. The planning concept is proposed as a means of achieving more effective utilization of resources in providing for recreational needs. Where data have been used in this study to support conclusions, they have been extracted from surveys conducted by agencies in the state of Washington and from selected studies undertaken elsewhere. Despite the limited availability of certain data, the method of analysis and the planning process presented in this report are considered to have general applicability.
