Traffic data collection, analysis, and forecasting for mechanistic pavement design by Cambridge Systematics( )

5 editions published in 2005 in English and held by 260 WorldCat member libraries worldwide

"TRB's National Cooperative Highway Research Project (NCHRP) Report 538: Traffic Data Collection, Analysis, and Forecasting for Mechanistic Pavement Design provides guidance for collecting traffic data to be used in pavement design and includes software--designated TrafLoad--for analyzing traffic data and producing traffic data inputs required for mechanistic pavement analysis and design. The TrafLoad software is designed to produce traffic data for input to the 2002 AASHTO pavement design software. TrafLoad is based on a new mechanistic-empirical approach to pavement design, it relies on axle load spectra rather than equivalent single axle loads. For each of four axle types, the load spectra specify the percentages of axles falling into each of several load ranges"--Publisher's description
An evaluation of granular overlays in Washington State : final technical report by Daniel John O'Neil( Book )

3 editions published in 1992 in English and held by 106 WorldCat member libraries worldwide

This study examined granular overlays by using three different techniques. First, previous research on the behavior of confined crushed rock layers was studied. Through these studies, information was sought concerning the stiffnesses that have been found in crushed rock layers, what can be done to improve the crushed rock layer, and the problems that have been encountered in working with confined crushed rock layers. Next, the usable life of the granular overlay was compared with that of other types of pavement resurfacing, including asphalt concrete (AC) overlays and BST. Finally, the granular overlays were tested to determine their properties and to measure the effect of different designs on their performance
Guidelines for spring highway use restrictions by Joe P Mahoney( Book )

7 editions published between 1985 and 1987 in English and held by 90 WorldCat member libraries worldwide

This report is a supplement to the video presentation "Guidelines for Spring Highway Use Restrictions." Air temperature based criteria (thawing index) were developed which can be used to estimate when to apply and remove load restrictions. This supplement provides guidelines for where to apply load restrictions, the amount of the load restrictions to apply and when to apply and remove load restrictions. Example calculations and a blank data collection sheet are also included

Quantifying incident-induced travel delays on freeways using traffic sensor data by Yinhai Wang( Book )

5 editions published in 2008 in English and held by 28 WorldCat member libraries worldwide

Traffic congestion is a major operational problem for freeways in Washington State. Recent studies have estimated that more than 50 percent of freeway congestion is caused by traffic incidents. To help the Washington State Department of Transportation (WSDOT) identify effective countermeasures against such congestion-inducing incidents, a thorough understanding of travel delays caused by incidents is essential. By using traffic data extracted from archived loop detector measurements and incident log data recorded by the WSDOT Incident Response (IR) team, this research project developed a new algorithm for quantifying travel delays produced by different incident categories. The algorithm applies a modified deterministic queuing theory to estimate incident-induced delay by using 1-minute aggregated loop detector data. Incident-induced delay refers to the difference between the total delay and the recurrent travel delay at the time and location influenced by the incident. The uniqueness of the delay calculation in this study is the use of a dynamic traffic-volume-based background profile, which is considered a more accurate representation of prevailing traffic conditions. According to the test results, the proposed algorithm can provide good estimates for incident-induced delay and capture the evolution of freeway traffic flow during incident duration. Because actual traffic data measured by loop detectors were used in this study to compute vehicle arrival and departure rates for delay calculations, the estimated incident-induced delay should be very close to the reality. Additionally, the proposed algorithm was implemented in the Advanced Roadway Incident Analyzer (ARIA) system. ARIA is a database-driven computer system that automates all the computational processes. More accurate incident delay information will help WSDOT improve its understanding of congestion-inducing incidents and select more effective countermeasures against incident-related traffic congestion on freeways
Travel indicators and trends in Washington State by Anne Vernez Moudon( Book )

2 editions published in 2005 in English and held by 28 WorldCat member libraries worldwide

This review of travel indicators in Washington State aims to understand similarities and differences between the state and the nation and to detect changes or special conditions that need to be considered in the future. The work is intended to support general transportation policies and future state-level transportation plans. None of the travel indicators reviewed strongly suggests that travel conditions in the state stand out in the national context. Two factors are prime in their association with travel demand: household income and development density. Stagnant income explains why the demand for car travel has slowed over the recent past, yet future demand for car travel may increase if the economy improves. On the other hand, demand could remain stable if development density continues to increase. Residential and population densities are positively associated with demand for modes other than single-occupancy vehicle (SOV) travel. Living in more compact residential areas and in alternative housing types, and renting versus owning a home, also relate to lower demand for SOV travel. Even at the aggregate level of national data, the Puget Sound region?s transportation context differs from that of rural or other urbanized regions in the state. State policies need to recognize at least three different markets for transportation, which are found in rural, small town, and metropolitan areas. Overall, Washington State needs to stay tuned to national projections about the likely impacts on travel demand and transportation of general economic trends, the slow down in household formation, growth in car ownership among new immigrants, an aging population with changing driving patterns, and population growth in densely populated areas --where transportation systems investments and land-use policies can affect future travel behavior

The use of small unmanned aircraft by the Washington State Department of Transportation by Edward Donald McCormack( Book )

3 editions published in 2008 in English and held by 25 WorldCat member libraries worldwide

Small, unmanned aerial vehicles (UAVs) are increasingly affordable, easy to transport and launch, and can be equipped with cameras that provide information usable for transportation agencies. The Washington State Department of Transportation conducted a series of UAV tests to evaluate their capabilities while also exploring institutional issues. These tests, while exploring the general capabilities of UAVs, focused on evaluating the use of a UAV as an avalanche control tool on mountain slopes above state highways. WSDOT's maintenance division has an active snow avalanche control program that is designed to reduce highway closure time and hazards to motorists, and the use of UAVs was seen as having some potential operational advantages. The UAVs also captured aerial images suitable for traffic surveillance and data collection. The evaluation found that the main limitation to UAV use is institutional, particularly the need to obtain approval to fly from the Federal Aviation Administration (FAA). This approval process will make UAV use a challenge, but these issues may change as the FAA considers new rules
