Freeway Operations and High-Occupancy Vehicle Systems 2007
TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2012 includes 15 papers that explore vulnerable sections of a national road network, the breakdown in merging sections of urban expressways, traffic diversion effect of ramp metering, modeling freeway diverging behavior, queue size estimation, and the benefits of a systemwide adaptive ramp-metering strategy. This issue of the TRR also examines the effect of detector spacing and sample size on the accuracy of freeway congestion monitoring, Amber alert messages, open road tolling, freeway bottleneck simulation, real-time screening of freeway traffic data, ramp metering effects on merging operations, safety impacts of a freeway managed-lane strategy, high-occupancy vehicle (HOV) lanes and hybrid vehicles, and simulation analysis of truck-restricted and HOV lanes.
Individual TRRs, which are published on an irregular basis throughout the year, consist of collections of peer-reviewed papers on specific transportation subject areas and modes. TRB's TRR Online service allows all visitors to identify papers of interest and review abstracts of those papers. Access to the full papers is available to service subscribers and employees of TRB sponsors. Papers may also be purchased on an individual basis.
Printed copies of TRR Journals may also be purchased on an annual subscription basis. Each year, TRB publishes approximately 45 volumes of the TRR Journal, containing more than 800 papers grouped by subject.
