Every year, the average American commuter spends a total of about one week of their life in traffic. Traffic congestion and the resulting delays costs major U.S. cities $121 billion in fuel costs and productivity loss annually, the equivalent of about $800 per commuter. Now, computer scientists in Pennsylvania have a new smart traffic signal […]
House committee leaders usually have a driver on staff to shuttle them between Hill votes, fundraisers, and speeches, but Transportation ad Infrastructure Chairman Bill Shuster let the technology take the wheel Wednesday. After a 30-mile ride in a driverless car developed by General Motors and Carnegie Mellon University, the Pennsylvania Republican said the experience – […]
Picture an all-electric vehicle cruising down the highway, emitting little noise and no noxious fumes. It’s such an improvement that you have to wonder why only a handful of all-electric vehicles are now available on the mass market. Here’s a big reason: Picture the driver of that same car getting a call from a relative […]
The purpose of this memorandum is to request your assistance in soliciting projects from State Departments of Transportation (DOTs). Metropolitan Planning Organizations (MPOs), Federal Land Management Agencies (FLMAs), and local governments on utilizing INVEST 1.0, FWA’s voluntary self-assessment tool, to assess and enhance the sustainability of their projects and programs. INVEST (Infrastructure Voluntary Evaluation Sustainability […]
INVEST (Infrastructure Voluntary Evaluation Sustainability Tool) is a practical, web‐based, collection of voluntary best practices and criteria designed to help transportation agencies integrate sustainable practices into their projects, plans, and programs. INVEST helps transportation agencies improve investment decisions while considering limited resources by addressing the sustainability triple bottom line ‐‐ enhancing economic, social, and environmental outcomes.
Since the 1950s transportation professionals have been able to quantitatively assess project alternatives based on mobility, and more recently in terms of environmental impact. Limited means have existed to assess the safety performance of different design alternatives. To help address that gap, the Highway Safety Manual (HSM) was published by the American Association of State Highway Transportation Officials (AASHTO), culminating ten years of research and development […]
This guide provides examples of opportunities for integrating the AASHTO Highway Safety Manual into the project development process. This includes integrating methods from the Highway Safety Manual into planning, alternatives development and analysis, design, operations, and maintenance. The guide provides a description of each of these steps in the project development process, and then provides a discussion of the […]
Report Number: FHWA/VCTIR 12-R8 To incorporate safety into the regional planning process, a Virginia-specific resource guide was recently developed for use by districts of the Virginia Department of Transportation (VDOT) and planning district commissions (PDCs). In order to determine how to enhance the implementation of the guide throughout Virginia, a pilot implementation of the guide […]
Publication No. FHWA-HRT-05-051 This paper presents estimates for the economic (human capital) and comprehensive costs per crash for six KABCO groupings within 22 selected crash types and within two-speed limit categories (= 50 mi/h)). The comprehensive costs include nonmonetary losses. To produce these cost estimates, previously developed costs per victim keyed on the AIS injury […]
