TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2043 includes 9 papers that examine high-speed rail in Japan and its interaction with air transportation; maintenance costs of high-speed lines in Europe; barriers to improving rail interoperability in European countries; and train slot cooperation in multicarrier, international rail-based intermodal freight transport. This issue of the TRR also explores rail tunnel risk analysis, decision support system for optimization of rail track maintenance planning, slab track testing under heavy axle loads, the effect of route rationalization on hazardous materials transportation risk, and the relationship between train length and accident causes and rates.
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.
