Transportation Research Board


TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2470 consists of 18 papers that explore a comprehensive framework for planning and assessment of traffic incident management programs; evaluation of hero-coordinated ramp metering installation; online scalable approach for identifying secondary crashes; freeway travel time forecasting; real-time queue-end detection on freeways with floating car data; mainstream traffic flow control at sags; design of emergency response system to minimize incident impacts; and estimation of congestion-related travel time losses on freeways.

This issue of the TRR also examines combining ramp metering and variable speed limits to improve motorway performance; use of data from point detectors and automatic vehicle identification to compare instantaneous and experienced travel times; identification of congestion factors for active transportation and demand management; potential benefits of integrated corridor management; optimal control of motorways by ramp metering, variable speed limits, and hard-shoulder running; accounting for travel time reliability and trip purpose in an agent-based approach to toll pricing; collection, screening, and evaluation of vehicle occupancy data; the use of psychological questions to help predict managed lane use; value of travel time savings; and high-occupancy toll lane’s impact on commuter bus and vanpool occupancy.
