The Transit Street Design Guide sets a new vision for how cities can harness the immense potential of transit to create active and efficient streets in neighborhoods and downtowns alike. Building on the Urban Street Design Guide and Urban Bikeway Design Guide, the Transit Street Design Guide details how reliable public transportation depends on a commitment to transit at every level of design. Developed through a new peer network of NACTO members and transit agency partners, the Guide provides street transportation departments, transit operating agencies, leaders, and practitioners with the tools to actively prioritize transit on the street."--Site Web de NACTO.

To help assess proposals for further changes in federal truck weight limits, Congress requested this study through Section 158 of the Surface Transportation and Uniform Relocation Assistance Act of 1987. To conduct the study, the National Research Council convened a special Transportation Research Board committee with experts in pavements, bridges, highway safety, freight transportation economics, motor vehicle design, highway administration, motor carrier operations, and enforcement of motor vehicle regulations. The study focused on four issues identified in the study request that involve potential changes to federal weight limits for Interstate highways: (1) Elimination of existing grandfather provisions; (2) Alternative methods for determining gross vehicle weight and axle loadings; (3) Adequacy of the current federal bridge formula; and (4) Treatment of specialized hauling vehicles--garbage trucks, dump trucks, and other trucks with short wheel bases that have difficulty complying with the current federal bridge formula. For each of these issues, the study committee estimated the nationwide effects of changes in federal limits proposed by the trucking industry, highway agencies, and other groups. Projections of heavy-truck miles by type of truck, region of the country, highway functional class, and operating weight were developed for a base case and alternative truck weight regulatory scenarios. These projections were then used to estimate impacts on truck costs, pavements, bridges, and safety.
Examines the feasibility and necessity of a central reporting system and computerized telecommunications data center capable of receiving, storing, and retrieving data concerning daily shipments of hazardous materials, and also capable of providing information to facilitate responses to accidents and incidents.
Paratransit services are more expensive to provide on a per-trip basis than fixed-route transit, so operating efficiencies could be achieved by attracting some paratransit riders to fixed route. The Guidebook identifies the characteristics and preferences of four distinct market segments: people with disabilities who use fixed-route transit; people with disabilities who use paratransit; others who currently use paratransit; and people with disabilities who normally do not use transit. The Guidebook also provides step-by-step procedures for estimating demand, locating bus stops, training drivers, providing travel training for patrons, marketing services, and evaluating successes.

This synthesis reports bridge inspection practices in the United States and selected foreign countries. The synthesis is a collection of information on formal inspection practices of departments of transportation (DOTs). These are primarily visual inspections and they provide data to bridge registries and databases. For U.S. inspection practices, this synthesis reports on inspection personnel, inspection types, and inspection quality control and quality assurance. Staff titles and functions in inspection programs are reported, together with qualifications and training of personnel, formation of inspection teams, and assignment of teams to bridges. Inspection types are described in terms of their scope, methods, and intervals. Quality control and quality assurance programs are reviewed in terms of the procedures employed, staff involved, quality measurements obtained, and the use of quality findings in DOT inspection programs. Foreign practices are presented in the same organization of inspection personnel, types, and quality programs. Comparisons of U.S. and foreign inspection practices are included. Information was obtained from a questionnaire sent to U.S. state transportation departments, similar questionnaires modified individually for transportation agencies in selected foreign countries, and formal documents used by transportation departments and agencies. These documents primarily included bridge inspection manuals, inspection training manuals, and technical memoranda, but also included blank forms for inspections, DOTs job descriptions for inspectors, and descriptions of inspection training courses. Overall, this synthesis includes information from forty U.S. state transportation departments and from roads agencies in eight foreign nations (Denmark, France, Finland, Germany, Norway, South Africa, Sweden, and the United Kingdom). The synthesis also includes, in an appendix, information from a few provincial and municipal transport agencies in Canada.
TRB¿s National Cooperative Highway Research Program (NCHRP) Report 622: Effectiveness of Behavioral Highway Safety Countermeasures explores a framework and guidance for estimating the costs and benefits of emerging, experimental, untried, or unproven behavioral highway safety countermeasures.
Federal planning legislation and regulations now mandate that state departments of transportation and metropolitan planning organizations consider the needs of freight when planning and programming transportation investments. While there are standard techniques used to forecast the movement of people, less attention has been paid to forecasting freight movements, and there are consequently fewer standardized techniques that state and local agencies can adapt to their local situation. This Toolkit is designed to provide transportation planners with the information they need to prepare forecasts of freight transportation by highlighting techniques successfully developed by state agencies across the country.
TRB¿s National Cooperative Highway Research Program (NCHRP) Report 617: Accident Modification Factors for Traffic Engineering and ITS Improvements explores the development of accident modification factors (AMFs) for traffic engineering and intelligent transportation system improvements. AMFs, also known as crash reduction factors, are designed to provide a simple and quick way of estimating the safety impacts of various types of engineering improvements, encompassing the areas of signing, alignment, channelization, and other traffic engineering solutions.
Efforts to preserve rail corridors or restore rail service to dormant rail alignments across the United States are very uneven. A handful of states have aggressive, well-funded programs to support the preservation or reuse of rail alignments; more states have modest programs to support short line operations on a case-by-case basis, but attach no value to corridor retention per se. In 2005, California completed what is perhaps the nations most comprehensive physical plant inventory of active and abandoned rail corridors; a review driven by interest in passenger rail and nonmotorized corridor interests. A foundation has been set to more fully lever these valuable alignments in this country's most populous state. This synthesis was undertaken to document current practices with respect to rail corridor preservation. State departments of transportation (DOTs), selected metropolitan planning organizations, commuter rail agencies, short line holding companies, and Class I rail carriers were all surveyed for information. Response rates to the survey were moderate, averaging 24%, and overall supporting the notion that preservation of rail alignments is not a high-priority issue in many jurisdictions. A handful of state respondents, however, had a great deal of experience and valuable observations on rail preservation policies and could be said to have become experts on this subject through their dealings with several dozen rail corridors over the past two decades. North Carolina, Ohio, and Pennsylvania DOTs each have serious, well-established rail sections and a history of successful preservation efforts.
