TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2080 includes 13 papers that explore the preempt trap of the highway-railway interface, fully actuated versus nonactuated coordinated phases, effectiveness of lead-lag phasing on progression bandwidth, high-resolution gueue discharge and the effect on signal phasing, integration of real-time pedestrian performance measures into traffic signal systems, microsimulation of split-cycle offset optimization technique and coordinated actuated traffic control, and piecewise optimum delay estimation for improved signal control. This issue of the TRR also examines microsimulation of traffic operations at intersections in malfunction flash mode, variable maximum green time to improve rural traffic signal operations, stopping behavior at urban signalized intersections, traffic controller performance of coordinated actuated signal systems during time-of-day transition, unacceptable video detector performance for dilemma zone protection, and robust synchronization of arterial actuated signals.
