Geometric Design and the Effects on Traffic Operations

TRB’s Transportation Research Record: Journal of the Transportation Research Board (TRR: Journal), No. 1961 includes a 2006 Fred Burggraf Award-winning paper that investigates the desirable length of spiral curves for two-lane, rural roads. This volume of the TRR: Journal also explores daytime high-speed passing maneuvers on rural two-lane, two-way highways; the use of a hierarchical, fuzzy-inference system to analyze expert opinions on median safety; the speed and crash rates of various right-turn lane designs; the design of safe roadsides in urban environments; and more.

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 45 volumes of the TRR Journal, containing more than 800 papers grouped by subject.
