TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2404 consists of nine papers that examine percentile speeds from a maximum operating speed frontier; operational effects of access point designs on freeway managed lanes; sight distance standards based on observational data for risk evaluation of passing; freeway deceleration speed-change lanes; and, triangabouts as an alternative for intersection with non-through arterial movement. This issue also examines double-crossover diamond interchanges in vissim microsimulation; pavement marking retroreflectivity and night crashes on a two-lane highway; analysis of safety effects of traffic, geometric, and access parameters on truck arterial corridors; and, an assessment of how drivers react to driveway activity.
