Accommodating Bicycle and Pedestrian Travel: A Recommended Approach is a policy statement adopted by the United States Department of Transportation. USDOT hopes that public agencies, professional associations, advocacy groups, and others adopt this approach as a way of committing themselves to in

This report summarizes traffic management systems maintenance practices utilized by state and local transportation agencies, identifies lessons learned from those practices, and offers professional analysis and recommendations for development of a comprehensive traffic management system maintenan

This regulation provides policies and procedures for implementing section 5206(e) of the Transportation Equity Act for the 21st Century (TEA-21), Public Law 105-178, 112 Stat. 457, pertaining to conformance with the National Intelligent Transportation Systems Architecture and Standards.

This guide is intended to introduce you to systems engineering and provide a basic understanding of how it can be applied to planning, designing, and implementing intelligent transportation systems (ITS) projects. The guide leads you step by step through the project life cycle and describes the

The regional ITS architecture was developed in the previous four sections. Now that you have a regional ITS architecture, this section describes ways that the architecture can be used.

In earlier sections, as the regional ITS architecture was developed, the transportation planning proce

This section describes TIM AMS methods and related applications. In each of the following subsections the current state of the practice is documented. The state of the practice (what is in current use) is discussed separately from the state of the art (that what has been researched).

The fifth edition of the Highway Capacity Manual (HCM2010), which updates HCM2000, will significantly enhance how engineers and planners assess the traffic and environmental effects of highway projects. 

The HCM2010: • provides an integrated multimodal approach to the analysis and

Work zone planning and management have become more challenging because of increasing travel demand and an aging roadway network infrastructure facing more frequent maintenance and major rehabilitation projects, while still needing to transport people and goods safely. In order to meet safety and

TRB’s second Strategic Highway Research Program (SHRP 2) S2-R11-RW-2: WISE Software Users Guide explains how to use the work zone impact and strategy estimator (WISE)—a decision support software system designed to help evaluate the impact of work zones and determine strategies to reduce

The TRB Committee for Review of the U. S. Department of Transportation's (DOT) Intelligent Transportation Systems (ITS) Standards Program has issued its fourth letter report to the ITS Joint Program Office. The report concludes that facilitating ITS data harmonization warrants JPO support.
