This report explores the relationships between transportation systems management and operations (TSMO) strategies and cooperative driving automation (CDA). It presents a high-level concept of operations (ConOps) in support of the CARMA PlatformSM sponsored by the Federal Highway Administration Office of Operations Research and Development. Developing this...

The Kentucky Transportation Cabinet (KYTC) maintains over two hundred steel bridges constructed with types of steel which are unknown. Kentucky Transportation Center (KTC) researchers have developed a procedure for determining steel tensile properties (0.2% yield strength and ultimate tensile strength) which can be used to help identify unknown steels. The...

Non-exhaust emissions of particulate matter constitute a little-known but rising share of emissions from road traffic and have significant negative impacts on public health. This report synthesizes the current state of knowledge about the nature, causes, and consequences of non-exhaust particulate emissions. It also projects how particulate matter emissions...

This report presents a practical process (referred to as a "tool") to guide practitioners through the selection of the appropriate On-Road Public Transport (ORPT) priority treatments for any road scenario. This step-by-step process can be used for applications relating to existing roads or a new/greenfield road development. It considers all forms of...

An increasing number of Accessible Pedestrian Signals (APS) have been installed at new or upgraded intersections to assist people with vision impairment to navigate streets. For un-signalized intersections and intersections without APS, people with vision impairment have to rely on their own orientation and mobility skills to gather necessary information to...

This Roundtable reviews a wide range of congestion control measures, analysing their effectiveness, financial and operational requirements, implementation time and public acceptability. A strong focus is on the role of technology in addressing congestion, including sensors, wireless systems, traffic light optimisation and trip planning data. The Roundtable...

In March 2010, the U.S. Department of Transportation (DOT) released a policy statement supporting the development of fully integrated transportation networks. The policy is to “incorporate safe and convenient walking and bicycle facilities into transportation projects.” The TRB National Cooperative Highway Research Program's NCHRP Synthesis...
