This summary report describes the September 1998 technology transfer scan tour to four European countries to learn how these countries are addressing their own safety issues, even as they comply with the increasing centralization of rules and regulations enacted by the European Commission. The key areas examined were human resources, vehicle safety systems, and regulations. The report includes recommendations and implementation strategies.

In October 2008 The Federal Highway Administration contracted a study team to conduct a two-part study to assess technology for the measurement of travel times for trucks through the Otay Mesa international border crossing into the US. The primary goal was to evaluate the ability of one of two technologies to accurately record travel times through the border zone. The specific objectives of the project were to: (1) Assess the effectiveness of a technology for automated capture of travel time for vehicles crossing the border. (2) Gather historical travel time data over the period of one year....

This report provides guidance to practitioners on effective strategies to mitigate the effects of congestion at signalized intersections. The scope is limited to single intersections and does not address network-level strategies. The strategies are defined in terms of their underlying objective. Under congested conditions, traditional objectives and performance measures shift from progression and minimizing delay to maximizing throughput and managing queues. Experts were interviewed to identify the strategies and tactics they used to address congested intersections, a discussion of their...

In SAFETEA-LU Section 1808, Congress required the U.S. Department of Transportation, in consultation with the Environmental Protection Agency (EPA), to evaluate and assess the direct and indirect impacts of CMAQ-funded projects on air quality and congestion levels to ensure the program's effective implementation. Phase II of the CMAQ Evaluation and Assessment responds to that request by exploring different practices and approaches that select agencies Nationwide use in CMAQ project selection and implementation. The study team conducted 1-day site interviews with Metropolitan Planning...

The objectives of this document are to provide: (1) guidelines on how to design a highway noise barrier that fits with its surroundings and performs its intended acoustical and structural functions at reasonable life-cycle cost; and (2) a state-of-the-art reference of common concepts, designs, materials, and installation techniques for the professional highway engineer, the noise barrier designer, and the non-professional community participant.

This report provides a guide for achieving a basic service model for traffic signal management and operations. The basic service model is based on simply stated and defensible operational objectives that consider the staffing level, expertise and priorities of the responsible agency. The report includes a Literature Review, which provides a review of the National Traffic Signal Report Card and Self- Assessment, case studies based on agency archetypes that provide an understanding of how agencies deliver traffic signal management services based on their resources and interviews with...
