Key Transportation Indicators


Book Description

A transportation indicator is a measure of change over time in the transportation system or in its social, economic, environmental, or other effects. Two National Research Council (NRC) studies recommended, as a matter of high priority, that the Bureau of Transportation Statistics (BTS) in the U.S. Department of Transportation (USDOT) develop a consistent, easily understood, and useful set of key indicators of the transportation system. The NRC's Committee on National Statistics and its Transportation Research Board, which conducted these studies, convened a workshop on June 13, 2000. The purpose of the Workshop on Transportation Indicators was to discuss issues relating to transportation indicators and provide the Bureau of Transportation Statistics with new ideas for issues to address.




Guide to Cross-asset Resource Allocation and the Impact on Transportation System Performance


Book Description

"TRB's National Cooperative Highway Research Program (NCHRP) Report 806: Guide to Cross-Asset Resource Allocation and the Impact on Transportation System Performance provides guidance and a spreadsheet tool to help managers with applying data-driven techniques to project prioritization, program development, scenario analysis, and target setting. The tool and guidebook are intended to assist managers with analyzing and communicating performance impacts of investment decisions. The software is available online only and can be download from TRB's website as an ISO image."--Publisher's description.




Progress Report on the National Transportation System Initiative


Book Description

This progress report describes the development of the NTS initiative and proposed future activities to bring the NTS to its full potential. A set of preliminary national transportation performance indicators is proposed. These performance indicators should be seen as the beginning of a process rather than as the definitive set of national transportation system indicators. A second part of the NTS analytical process involves the development and application of a national transportation network analysis capability (NTNAC) that will provide the ability to evaluate the national network in a multi- modal manner. Using the NTNAC, problems with the Nation's transportation system can be identified and policy options to address these problems evaluated. The report concludes with a discussion of the use of the NTS within the Department. It is proposed that the results of the analyses carried out using the national transportation performance measures and the NTNAC in the assessment of the Nation's transportation system, the identification of issues, and the analysis of options be presented in biennial State of the National Transportation System reports.







Urban Street Design Guide


Book Description

The NACTO Urban Street Design Guide shows how streets of every size can be reimagined and reoriented to prioritize safe driving and transit, biking, walking, and public activity. Unlike older, more conservative engineering manuals, this design guide emphasizes the core principle that urban streets are public places and have a larger role to play in communities than solely being conduits for traffic. The well-illustrated guide offers blueprints of street design from multiple perspectives, from the bird’s eye view to granular details. Case studies from around the country clearly show how to implement best practices, as well as provide guidance for customizing design applications to a city’s unique needs. Urban Street Design Guide outlines five goals and tenets of world-class street design: • Streets are public spaces. Streets play a much larger role in the public life of cities and communities than just thoroughfares for traffic. • Great streets are great for business. Well-designed streets generate higher revenues for businesses and higher values for homeowners. • Design for safety. Traffic engineers can and should design streets where people walking, parking, shopping, bicycling, working, and driving can cross paths safely. • Streets can be changed. Transportation engineers can work flexibly within the building envelope of a street. Many city streets were created in a different era and need to be reconfigured to meet new needs. • Act now! Implement projects quickly using temporary materials to help inform public decision making. Elaborating on these fundamental principles, the guide offers substantive direction for cities seeking to improve street design to create more inclusive, multi-modal urban environments. It is an exceptional resource for redesigning streets to serve the needs of 21st century cities, whose residents and visitors demand a variety of transportation options, safer streets, and vibrant community life.




Transportation Decision Making


Book Description

This pioneering text provides a holistic approach to decisionmaking in transportation project development and programming, whichcan help transportation professionals to optimize their investmentchoices. The authors present a proven set of methodologies forevaluating transportation projects that ensures that all costs andimpacts are taken into consideration. The text's logical organization gets readers started with asolid foundation in basic principles and then progressively buildson that foundation. Topics covered include: Developing performance measures for evaluation, estimatingtravel demand, and costing transportation projects Performing an economic efficiency evaluation that accounts forsuch factors as travel time, safety, and vehicle operatingcosts Evaluating a project's impact on economic development and landuse as well as its impact on society and culture Assessing a project's environmental impact, including airquality, noise, ecology, water resources, and aesthetics Evaluating alternative projects on the basis of multipleperformance criteria Programming transportation investments so that resources can beoptimally allocated to meet facility-specific and system-widegoals Each chapter begins with basic definitions and concepts followedby a methodology for impact assessment. Relevant legislation isdiscussed and available software for performing evaluations ispresented. At the end of each chapter, readers are providedresources for detailed investigation of particular topics. Theseinclude Internet sites and publications of international anddomestic agencies and research institutions. The authors alsoprovide a companion Web site that offers updates, data foranalysis, and case histories of project evaluation and decisionmaking. Given that billions of dollars are spent each year ontransportation systems in the United States alone, and that thereis a need for thorough and rational evaluation and decision makingfor cost-effective system preservation and improvement, this textshould be on the desks of all transportation planners, engineers,and educators. With exercises in every chapter, this text is anideal coursebook for the subject of transportation systems analysisand evaluation.
