This research presents a signal control strategy utilizing vehicular trajectory-driven optimization method. Band Finder provides individual drivers equipped with opt-in device (i.e. smartphone or tablet) with advisory speed information enabling to minimize overall travel time of the vehicle while negotiating signalized corridor. Signal status parameters such as cycle length and remaining green/red time are continuously captured. At the same time in-vehicle unit provides vehicle position information through cell-phone global positioning system (GPS) receiver. Both inputs are then used by optimization algorithm to provide optimal vehicle speed that will achieve minimal vehicle delay along the signalized corridor. To calculate the most optimal advisory speed for individual vehicles a non-linear optimization algorithm was utilized. The concept was evaluated using microsimulation in PTV VISSIM. The results for selected signalized corridor in Woodbridge, New Jersey indicate 1.2% to 5.4 % reduction in overall corridor travel time depending on different market penetration and traffic volume conditions.
