Abstract
TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2030 includes 11 papers that examine rumble strip design, urban wayfinding signs, crash reduction factors for overhead flashing beacons at rural intersections, design standards for speed cushions, driver behavior at dilemma zones at signalized intersections, minimum signal sight distance, and headlight swivel angles at curves on rural two-lane highways. This issue of the TRR also explores driver actions at railroad-highway grade crossings, warranting traffic signals by proximity of railroad grade crossings, traffic control devices and barrier systems at grade crossings, and grade crossing evaluation methodology.
