Traffic control devices, visibility, and rail-highway grade crossings 2005. A peer-reviewed publication of the Transportation Research Board TRB.

TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 1918, examines factors affecting safety at rail–highway grade crossings, the legibility of unlit freeway guide signs, the flashing yellow arrow in traffic signal displays, radius-estimating techniques for horizontal curves, and the effectiveness of dynamic speed display signs. Many of the papers contained in this volume were presented at the 84th Annual Meeting of the Transportation Research Board in January 2005. (Author/publisher)
