TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2128 includes 23 papers that explore green time at congested traffic signals, traffic signal maintenance and operations needs, railroad-preempted intersections, three dimensional mapping of inductive loop detector sensitivity, cycle length performance measures, bus priority strategies on arterials controlled by SCOOT, tolerances for magnetometer orientation and field calibration procedure, and optimization of coordinated-actuated traffic signal system. This issue of the TRR also examines bicyclist intersection crossing times, left-turn signal control, optimizing traffic control to reduce fuel consumption and exhaust emissions, optimizing signal timings from the field, platoon-priority and advance warning flasher system at high-speed intersections, prediction of red light running, microscopic modeling of traffic signal operations, lost time and cycle length for an actuated traffic signal, specifying vehicle detection performance, local synchronization control scheme for congested interchange areas, distributed Ethernet network of advanced pedestrian signals, comparison of before-after versus off-on adaptive traffic control evaluations, generating traffic scenarios for large arterial networks, evaluating green-extension policies, and safety evaluation for intergreen intervals at signalized intersections.
