Pearson,W. H. | WA-RD 614.1 | Protocols for Evaluation of Upstream Passage of Juvenile Salmonids in an Experimental Culvert Test Bed | 2005 | WSDOT |
Abstract:
The Washington State Department of Transportation (WSDOT) and its partner agencies developed a research program to design new and retrofit culverts. The goal of this program is to identify culvert bed configurations, designs, and associated hydraulic conditions that allow successful movement of juvenile salmonids upstream, while safely passing water, sediment, and debris downstream. WSDOT, in cooperation with the Washington Department of Fish and Wildlife (WDFW), constructed a culvert test bed at the WDFS's Skookumchuck Hatchery in western Washington State. Battelle conducted experiments to establish protocols for future research on bed conditions, culvert shape, etc. This technical report describes various protocols, such as time of day, duration of test, and density of test fish, and provides hydraulic and biological characterizations of a baseline culvert.

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.

Hill,K. | WA-RD 621.1 | Roadside Vegetation Management Study: Literature Review, Interview Summaries, and Decision Framework | 2005 | TRAC/UW |
Abstract:
This study was conducted for the Washington State Department of Transportation (WSDOT) to explore both the need for and the variety of alternatives to the use of an annual application of herbicides for removing vegetation in the area immediately adjacent to the pavement edge. Our study approached these questions in two different ways, developing both a literature review and a set of interviews with people who have specific knowledge or views of these issues. We conducted interviews with three groups of people to identify issues, maintenance alternatives, and significant literature references: (1) staff at other federal, state, and county transportation agencies, (2) staff and volunteers who work with advocacy groups, and (3) researchers at academic institutions who specialize in related areas. Our literature review contains a set of citations that present related management issues and alternative practices. The abstracts for these references were included when available. To summarize what we learned from the interviews and literature sources, we developed a decision framework that could be used to guide WSDOT district maintenance staff in formulating management plans for vegetation. The decision framework differs from current practice primarily in that it begins with the assumption that maintenance of the area immediately adjacent to the pavement is not necessary unless some particular, observable condition triggers the need for such maintenance.

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).

Kristof,T. | WA-RD 597.1 | Assessing the Benefits of Traveler and Transportation Information Systems | 2004 | TRAC/UW |
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.

Muench,S. T. | WA-RD 476.2 | Evaluation Of The Transtech Pavement Quality Indicator | 1999 |
Abstract:
Recently, WSDOT acquired a non-nuclear, non-destructive, density measuring device manufactured by TransTech called a Pavement Quality Indicator (PQI). TransTech's PQI measures pavement density indirectly by measuring its dielectric constant. A non-nuclear gauge is advantageous because it contains no radioactive source and is therefore not subject to radiological controls, and it can obtain readings in about 5 seconds versus to 4 minutes with a nuclear gauge. Currently, TransTech is collecting data from different agencies to determine the suitability for measuring asphalt pavement density. This brief study presents density measurements from PQI and compares them with nuclear density gauge and core density measurements from three WSDOT 1998 paving projects. This evaluation was a secondary study to 1998 study Asphalt Concrete Temperature in Washington State; therefore this study's experimental design was based entirely on the Temperature study requirements, which resulted in non-random samples and multiple populations within the same sample groups. Despite these problems, results indicate that, when averaged, PQI readings compare favorably with both nuclear measurements and core measurements.

Trowbridge,A. | WA-RD 415.1 | The Potential for Freight Productivity Improvements Along Urban Corridors | 1996 | TRAC/UW |
Abstract:
The impacts that would result from providing "reserved capacity" for trucks rather than restricting trucks are considered in this study. In the extreme case, trucks would be allowed to travel in a dedicated or exclusive lane. A more moderate approach would be to provide a cooperative dedicated lane in which vehicles such as trucks and buses could share a common lane and yet be separated from general traffic.The study determined the following. Reserved-capacity strategies for trucks would offer (1) nearly $10 million in annual travel time savings for the trucking industry, (2) a savings of about 2.5 minutes per average truck trip (less than 8 percent savings in trip travel time), and (3) almost $30 million in annual travel time savings for single-occupancy vehicles in the Seattle region. The difference in travel times between the reserved-capacity strategy that would add trucks to the existing HOV lanes and the one that would add an exclusive truck lane would be insignificant, providing little justification for the construction of an exclusive truck lane. In all likelihood, the impact of reserved-capacity strategies on safety would be small, depending on the particular reserved capacity strategy. Reserved capacity strategies for trucks would accelerate pavement deterioration in the reserved lanes, but the reduction in the pavement deterioration rates of the general purpose lanes might help to balance future reconstruction costs. Surveys of the general public and subsequent statistical analysis showed considerable resistance to reserved-capacity strategies for trucks. However, this resistance is not unlike that encountered when HOV lanes were first considered.It is the recommendation of this study that the idea of reserved-capacity strategies for trucks continue to be presented to the trucking industry, to the public, and to other impacted agencies for discussion and consideration. The study showed that the adverse impacts of such strategies are easily manageable and there is at least potential for freight-productivity improvements.

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.

Carr,D. H. | WA-RD 194.1 | Clear Zones for Local Agencies | 1989 |
Abstract:
The reported study was used to investigate clear zone practices, policies and standards that are employed both within Washington State and throughout the United State. Emphasis was placed on those standards or guidelines that apply to local city and county roadways which are predominately low volume and low speed facilities.The review of nationwide clear zone practices pointed to a need for a set of clear zone guidelines or standards that apply specifically to low volume, low speed facilities. The research also pointed to the need for guidelines or standards that could be easily applied by city or county agencies with limited staff and limited budgets.One of the findings of the research is a step by step format for agencies to use in establishing a program to address existing clear zone deficiencies.

The research also pointed to the need for guidelines or standards that could be easily applied by city or county agencies with limited staff and limited budgets.One of the findings of the research is a step by step format for agencies to use in establishing a program to address existing clear zone deficiencies.

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.

University of Washington | WA-RD 023.1A | Operating Manual, Methods and Equipment Developed During The Project (Central Avalanche Hazard Forecasting), July 1975-M... | 1978 |
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.

LaChapplle,E. R. | WA-RD 023.3 | Central Avalanche Hazard Forecasting - Final Report, Phase II 954 | 1977 |
Abstract:
This report reviews the second year of work on the Washington State Highway Commission Department of Highways project Central Avalanche Hazard Forecasting (WSDH Agreement Y-1700) to test the feasibility and effectiveness of central avalanche forecasting for the Cascade Mountain passes and adjacent area. The possibilities and techniques for improving both mountain weather and related avalanche forecasts for use by WSDH during winter operation in the mountain passes were further explored, and, secondarily, the usefulness of an area wide forecasting service to other cooperating agencies. This report defines and significant changes from the first year of operation in collection, assimilation or transmission of snow, weather and avalanche data by the Forecasting Office, and details modifications of the data network itself, especially new instrumentation and telemetry equipment . Weather and avalanche forecasting accuracy and reliability are assessed by comparing daily weather and avalanche forecasts with file d data. The conceptual framework and analytical methods used by forecasters to deduce current and probable future avalanche activity from the available data network input and current and extrapolated meteorological data are presented. A general preliminary guide to forecasting methodology for the Washington Cascades is defined and discussed.

LaChapplle,E. R. | WA-RD 008.7 | Cascade Passes - Avalanche Atlas Part I - Chinook, Cayuse, White And Snoqualmie Passes | 1974 |
Abstract:
This present compilation of avalanche paths affecting Washington State highways extends in the same format the information published in 1971 as the North Cascades Highway Avalanche Atlas. Part 11, in preparation, will cover Stevens Pass and Tumwater Canyon.The North Cascades Highway Atlas was prepared on the basis of extensive aerial and ground reconnaissance in a hitherto inaccessible wilderness area where no previous record of avalanche occurrence was available. Compilation for the Cascades Passes has proceeded on the same basis, with the added advantage that all of the areas in question have long been traversed by highways for which considerable historical records exist . It is necessary, though, to note that such a record has proven to be less advantageous than might be expected. In the case of the North Cascades Highway, identification of avalanche paths was based on objective appraisal of terrain and vegetation patterns, leading to an accurate and highly consistent compilation. In the present Cascade Passes Atlas, there are many instances where objective evidence and historical accounts fail to agree. Moreover, the nomenclature, rather than being assigned consistently, has developed -- ad hoc over the years and varies with individuals and agencies . These conflicts have been resolved in the final editing of this Atlas according to the best available evidence, but in some cases necessarily in an arbitrary fashion. The Snoqualmie Pass section of this Atlas includes reproductions of sketches prepared by the Department of Highways for use in recording avalanche occurrences. These sketches are included here to illustrate this mode of avalanche recording, since it is a valuable method for systematically accumulating an historical record of avalanche frequency and behavior.

Leonhardt,K. | WA-RD 011.2 | Recreational Trip Characteristics And Travel Patterns - Second Phase Of The Washington State Recreational Travel Study 9... | 1973 |
Abstract:
The objectives of this research are two-fold: 1) to identify characteristics of recreational trips, and 2) to identify factors influencing the distribution of recreational trips. Characteristics of recreational trips have been identified on the basis of data collected from different state agencies in the State of Washington. Seven recreational trip purposes which are characteristic for the State of Washington have been identified in this study: 1) camping trips, 2) hunting trips 3) fishing trips, 4) visiting beaches and clamming, 5) snow skiing, 6) driving for pleasure and sightseeing, and 7) others.The analysis has been performed basically for the spatial and temporal distribution of recreational trips. Spatial distribution relates to the location of the recreational opportunities which can clearly be distinct for each of the trip purposes and is further characterized by the trip-length frequency connected with each of these trip purposes. Temporal distribution is related primarily to the seasons within which the activity corresponding to the trip purpose can be pursued.A further reason for classifying recreational trips into these seven purposes is the difference in travel behavior that can be observed in connection with trip purposes. For example, hunting, fishing, and snow skiing are trips with a distinct destination, and the trip maker tends to select the shortest route to his destination in order to minimize the travel time. Travel to the trip destination is not, therefore, an essential part of the recreation experience. On the other hand, driving for pleasure and sightseeing creates different travel behavior.

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.
