TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 1917 explores the development of a more accurate, cost-effective methodology for estimating vehicle miles traveled; a reality-based approach to soliciting stated preference data; possible causes of loop errors under non-forced-flow traffic conditions; and wireless magnetic sensor networks as a low-cost alternative to inductive loops for traffic measurement.

Individual TRR Journals, which are published on an irregular basis throughout the year, consist of collections of peer-reviewed papers on specific transportation subject areas and modes.  Abstracts of papers that make up this TRR are available through TRB's Publication Index.

TRR Journals may also be purchased on an annual subscription basis.  Each year, TRB publishes approximately 40 volumes of the TRR Journal, containing more than 650 papers grouped by subject.
