TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2042 includes 12 papers that explore transit intermodal facilities and capacity; light rail, commuter rail, and rail transit; and major activity center circulation systems. Specific papers examine airport ground access, consistency in transit passenger arrivals, transit quality of service and employment accessibility, process management in public transit planning, active transit signal priority for streetcars, successful historic streetcar service, light rail cost functions and technical inefficiency, boarding and alighting experiments, bus-rail service integration, and commuter rail circulator route network design. This issue of the TRR also explores new-generation personal rapid transit technologies and cluster-based optimization of urban transit hub locations.
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.
