Abstract:
On October 2, 2021, Sound Transit of the Puget Sound region of Washington state started Link light rail service to three new stations on the 1 Line . These stations serve the University District, Roosevelt, and Northgate in Seattle. In coordination with the station openings, Sound Transit, King County Metro, and Community Transit of Snohomish County restructured many of their routes that had previously provided express service to downtown Seattle and the University District. This report examines the changes in travel behavior that occurred as a result of those change in transit service. Comparisons are made primarily between September / October 2019 (the last pre-Covid-19 year) and September / October 2021.

Abstract:
This report was commissioned as part of the Washington State Department of Transportation’s (WSDOT) Equity in Planning (EiP) project. It presents knowledge drawn from transportation equity academic literature, practice-oriented literature, community engagement, geospatial (GIS) analysis, and a survey of planning professionals. The project aims to comply with Washington state’s Environmental Justice (EJ) legislation, SB 5141, known as the HEAL (Healthy Environment for All) Act. The HEAL Act sets the goal that 40 percent of major state expenditures be directed toward overburdened communities and vulnerable populations. It mandates that EJ analyses be performed by seven state agencies, including WSDOT. This report identifies leading indicators of transportation equity that WSDOT can incorporate into its planning processes for long-range, regional, and corridor planning initiatives.

Abstract:
This report documents the results of five Advanced Traveler Information System (ATIS) project evaluations performed for the Washington State Department of Transportation. The projects encompass a range of devices in both urban and rural environments. Guidelines and lessons learned for planning and operating ATIS programs were then developed from the evaluation results. These observations were clustered into common themes in the areas of maintenance, rural projects, project management, staffing, training, support, and customer response. As part of this effort, a standardized evaluation approach for ATIS projects was developed. The approach was designed to focus on technical, management, and organizational lessons learned. The method was effective in producing useful information about ATIS benefits and deployment issues. Using that approach, an additional nineteen required ATIS evaluations will be performed in a second project phase. The additional evaluations will also provide an opportunity to further verify and strengthen the initial lessons learned, as well as to expand the method.

Abstract:
High occupancy vehicle (HOV) lanes, also known as carpool lanes and diamond lanes, are designated for use by carpoolers, transit riders, ride sharers and motorcyclists that meet the occupancy requirement. By restricting access, the HOV lanes benefit users by allowing them to travel the freeway system at a faster speed, thus saving time, and experiencing greater time reliability in comparison to motorists on general purpose (GP) lanes. To accurately evaluate the system's effectiveness, a state policy requires an annual HOV system report to document system performance, examining the HOV lanes' person-carrying capability, travel time savings, and trip reliability benefits in comparison to adjacent GP lanes. HOV lane violation rates are also evaluated. This report describes the results of an extensive monitoring effort of HOV lane use and performance in the Puget Sound area in 2002. It presents an analysis of data collected to describe the number of people and vehicles that use HOV lanes, the reliability of the HOV lanes, the travel time savings in comparison to GP lanes, violation rates and public perceptions. This information is intended to serve as reliable input for transportation decision makers and planners in evaluating the impact and adequacy of the existing HOV lane system in the Puget sound area, and in planning for other HOV facilities. This is volume 1 of a two-volume set. Volume 2 provides an overview of major trends in HOV lane performance by comparing data presented in the 2000 HOV Performance Report.

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.

Abstract:
The goal of advanced traveler information systems (ATIS) is to provide travelers with information that will facilitate their decisions concerning route choice, departure time, trip delay or elimination, and mode of transportation. The benefits of ATIS projects can be evaluated through field studies, simulation software, and surveys. An evaluation method called the ITS Deployment Analysis System (IDAS) is suggested for use by the Washington State Department of Transportation (WSDOT). IDAS is a "sketch" planning tool intended for screening and prioritizing all intelligent transportation systems (ITS) projects (not just ATIS projects). The software evaluates a number of benefits. These are determined by changes attributable to the deployment of ITS in vehicle miles traveled (VMT), vehicle hours traveled (VHT), volume-capacity (v/c) ratios, and vehicle speeds throughout a given network. The IDAS evaluation depends on a number of assumptions that affect the calculations of costs and benefits. The IDAS developers recommend that these assumptions be inspected by local agencies and adjusted to better represent local conditions. The assumptions about the impacts on VMT, VHT, v/c ratios, and vehicle speed are particularly important. Consequently, suggestions are made within this report for adjustments that WSDOT should make to these default values. These values will allow the WSDOT to successfully employ IDAS for ATIS evaluation.

Abstract:
The Washington State Pavement Management System (WSPMS) offers an organized methodology that WSDOT decision makers use to determine optimum strategies for providing and maintaining pavements in a serviceable condition over a given period of time. It also helps improve decision-making efficiency, provide feedback on the consequences of decisions, and ensure the consistency of decisions made at different management levels within WSDOT. Unfortunately, it is not possible, by simply scanning the WSPMS, to pinpoint reasons why pavement sections made of the same general surface materials and subjected to similar traffic and climatic conditions differ in performance. What the WSPMS can do is assist engineers in developing a candidate list of pavement sections with superior and inferior performance. Common characteristics that linkmultiple pavement sections are of particular interest, in part because they may reflect a common practice(e-g., nighttime construction) that leads to superior or inferior performance.This study undertook various extensive analyses and comparisons to help illustrate common attributes of Washington state pavements with superior and inferior performance. The research also reviewed field performance data for Interstate 90 within the 1999 version of the WSPMS. The purpose was to examine all pavement segments on the 480 km of Interstate 90 within Washington state.Reducing variability will allow WSDOT to produce more consistent pavement performance and will allow increasingly effective planning and forecasting. An almost certain byproduct of this increased planning effectiveness will be a more efficient allocation of available funding.

Abstract:
The Seattle Wide-area Information for Travelers (SWIFT) Operational Test was intended to evaluate the performance of a large-scale, urban Advanced Traveler Information System (ATIS) deployment in the Seattle area. With the majority the SWIFT system completed by June 30,1996, the SWIFT Field Operational Test (FOT) evaluation was conducted from July 1, 1996, through September 20, 1997. The unique features of the SWIFT ATIS included the provision of information for multiple transportation modes, the delivery of this information using three different devices, and the use of FM sideband as the primary communications medium. This report details the findings for the SWIFT Consumer Acceptance Study based on the evaluation objectives that were identified in the SWIFT Evaluation Plan (1995). The primary objectives of the SWIFT Consumer Acceptance Study were to assess the following: Importance of traveler information in travel planning, Usefulness of SWIFT traveler information in travel planning, Minimum set of user services and device features required to provide viable product and services, User perceptions of SWIFT device usefulness, Willingness-to-pay for different services. User perceptions of changes in travel convenience and efficiency, User perceptions of changes in traffic congestion, air quality, energy consumption, and safety. ,

Abstract:
This document presents information on the state of the art in multimodal evaluation for planning and programming based on information gathered in 1991 and 1992. Sources include mail survey responses of state Departments of Transportation (DOTs), Canadian provinces, and regional governments, as well as a literature search. As expected, this information-gathering process uncovered few good examples of multimodal planning and programming evaluation, a result that reflects the largely inflexible modal funding process in place prior to the Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991 and the slow process of change in transportation planning procedures. Three major federal efforts in multimodal evaluation are reviewed in this synthesis, along with 18 state, regional, and corridor projects that were uncovered in the survey process. Five of the surveyed projects were developed into case studies that reflect current practice in intercity, regional, and urban corridor evaluation. An extensive review of evaluation criteria and measures of effectiveness is provided. This synthesis concludes that new training, assistance, and guidelines for multimodal. evaluation should be provided at the national level, with an emphasis on updating and expanding existing resources. It also concludes that effective multimodal evaluation is hindered by the lack of a commonly accepted multimodal measure of mobility.

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.

Abstract:
Road maintenance is characterized as the continuing care of the roadway and providing for its intended use until such time as needed improvements are identified and undertaken. Within the scope of recurrent and deferred maintenance activites, opportunities are identified to improve cost effectiveness of surfacing and ditch maintenance and reduce future capital improvements.The selection of equipment, materials and procedure is either a commitment to long-term transportation system goals or they create future constraints. The author shows how subgrade and base course damage can be detected and corrected while avoiding actions that add costs or merely hide the problems; use of geotextiles may benefit road conditions but interfere with future maintenance; selection of dust palliatives may either increase or decrease future costs; basic equipment types and limitations affect maintenance prescriptions; good operating practices improve productiona and protect equipment; some historic practices increase the risk of equipment damage; drainage affects road stability and serviceability; to reshape or smooth blade surfacing and clean roadside ditches; an effective maintenance management system helps identify and prioritize needed improvements.Planning, scheduling and performing roadside ditch, travelway and shoulder maintenance requires knowledge and expertis to be successfully and economically accomplished. Basic maintenance approaches and concepts are suggested and new considerations proposed for aggregate, earth and native surfaced roads.

Abstract:
Over the last 25 years, the Urban Mass Transportation Administration (UMTA) has developed a comprehensive series of urban transportation planning computer programs. Known as the Urban Transportation Planning System (UTPS), these programs require extensive and detailed documentation best suited for large, regional planning agencies. To facilitate urban travel forecasting by smaller agencies and educational institutions, this manual, the Urban Transportation Planning System / Simplified Limited Instruction Manual (UTSP/SLIM) was developed. UTPS/SLIM simplifies and repackages, without changing the software, the existing UTPS documentation. The UTPS/SLIM user is presented with only the most relevant and necessary program functions.

Abstract:
This study was undertaken to measure and assess current transportation behavior, attitudes, and adjustments people have made or are planning to make to cope with higher costs of transportation and energy shortages. A secondary objective was to develop an effective and inexpensive system to collect a sizeable amount of multimodal data for various types of travel from a statistically reliable sample of modal data for various types of travel from a statistically reliable sample of households in the State of Washington. Telephone interviews of approximately 15 minutes in length were conducted with 2,500 households in 1980 and 2,000 homes in 1983, with both samples having a 95 percent confidence level. Residents of metropolitan, urban and rural areas were included. The households interviewed were selected by a random computer search of telephone numbers. Respondents were screened to ensure that an adult member (18 years or older) of the household was interviewed. The questionnaire dealt with the travel habits of the household rather than just the person being interviewed. Travel to work, local travel, long distance travel, recreational travel, use of public transit and other modes of travel, as well as vehicle ownership trends were topics covered in the interviews. The household\\\'s travel patterns two years prior to the interview, as well as current behavior and future plans were included. The replies to the questions indicated that people were concerned about transportation problems and were willing to provide detailed facts and opinions about their household\\\'s transportation behavior.

Abstract:
In high growth areas, highways frequently become congested as the result of land use changes. Local use controls have not prevented the adverse impacts. Further, state funds are inadequate to address the critical problems in growth areas. This study investigates six study areas in Washington compare land use change impacts and the effectiveness of the various procedures applied to prevent or correct such problems and to fund highway improvements in growth areas. A survey of practice in other states provides information concerning their approaches to the problem. The study concludes that comprehensive land use planning supported by inter-agency cooperation has been ted. Local governments have applied a number of innovative techniques for financing local roads and streets. Cooperative interagency planning before growth is out of control has benefited both the local jurisdiction and the state. However, state and local jurisdictions lack the authority to apply these techniques to state highways in Washington State. The study makes recommendations for increasing interagency cooperation and for legislative remedies.

Abstract:
The Central Avalanche Hazard Forecasting project has been funded by the Washington State Highway Commission since July 1975 in order to test the feasibility and effectiveness of central avalanche forecasting for the Cascade Mountain Passes and adjacent territory . Historically, avalanche forecasting in the Cascade Mountains has been done locally on an area-by-area basis by Highway Department personnel and by Forest Rangers and professional ski patrolmen at individual ski areas. This project explored the possibilities of improving both mountain weather and related avalanche forecasts for use by WSDOT during winter operations in the mountain passes and, secondarily, explored the usefulness of anarea-wide forecasting service to other, cooperating agencies. The aim of this work has been to establish the technical and administrative framework for an operational, on-going mountain weather and avalanche forecasting service for Western Washington under the joint support of interested public agencies. This aim has been achieved in autumn 1978 by the operation of an avalanche forecasting office administered by the US Forest Service, housed by the National Weather Service, and supported by WSDT, with additional peripheral support from both the public and private sectors. Previous reports published by the project include: Interim Report, June 1976 (Report No. 23.2); Final Report, June 1977 (Report No. 23.3)Implementation Report, December 1978, which will be published in Spring 1979If you would like to obtain copies of any of these reports, contact WSDOT Public Transportation and Planning Division in Olympia (SCAN 234-61 49) or the Avalanche Research Office on SCAN 323-7180 or Write Avalanche Research,Department of Atmospheric Sciences AK-40, University of Washington, Seattle,Phil Taylor, Research Engineer, has done an outstanding job of developing much of this equipment and devising methods of operation. He is, unfortunately, no longer with the University. He will be working in Autumn 1978 with the US Forest Service as a consultant in addition to his continuing work with the US Geological Survey. This Operating Manual is intended to be an informational document with limited distribution and its format reflects that informality.

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 study is to produce guidelines that provide specific, operational and action oriented assistance to those responsible for planning and transportation surveys as a community involvement tool. A considerable amount of recent transportation survey experience along with the provision of technical information from private urban opinion survey organizations was researched and analyzed for inclusion in these guidelines. By discussing and comparing the relative merits of different survey techniques, the sampling process, questionnaire design, and examples of past surveys, these guidelines cover the theoretical as well as the practical side of the surveying process. The presentation of this information is in such a that it can be used by field staff to insure that this vital element of a community involvement program can be performed in an efficient and effective manner.

Abstract:
Forty-eight bridge decks were investigated for deterioration using visual , mechanical , electrical and chemical techniques. Data from the various techniques and the techniques themselves were compared and evaluated, resulting data base for Washington\'s bridges and recommendations for efficient condition determinations. Of the thirty-seven bridges for which all four types of inspection could be accomplished, twenty-nine were deteriorating as evidenced by delaminated concrete, and only two had non-deteriorating scores for all four techniques. None of the investigative techniques used in the project have been shown able to predict deck deterioration problems six to eight years in advance, our desired time period for project planning. The mechanical technique, commonly referred to as the \"chain drag\", is the method recommended for continued use by bridge inspection crews. Forty-eight bridge decks were investigated for deterioration using visual, mechanical, electrical and chemical techniques.

Abstract:
The objective of this study was to present criteria and procedures for evaluation of Joint Development (JD) above, below, or beside s t a t e highways. Application of the procedures a re-illustrated over a wide range of joint development situations, both (1) for establishing state or local J D policy, and (2) for making decisions about JD projects in a more timely and comprehensive manner, and in a way that will contribute toward improving the quality or urban life or the enhancement of rural environments. The approach taken in the Guidelines is sequential, systematic, and interdisciplinary; that is, it uses a series of successively more detailed and comprehensive planning and evaluation procedures for JD decision-making, relying on a wide range of specified physical, economic, social, and legal criteria. In use, the Guidelines envision a three- stage planning and evaluation process:(1) identification of the need or potential for J D projects, (2) comparison of project proposals against policies, criteria and standards designed t o avoid or minimize negative impacts and increase favorable impacts; and (3) refined definition of costs and benefits when warranted.

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.
