This research evaluates the impact of In-vehicle Signal Advisory System (ITSAS) on\nsignalized arterial. ITSAS provides individual drivers equipped with a mobile communication device\nwith advisory speed information enabling to minimize the time delay and fuel consumption when\ncrossing intersection. Given the instantaneous vehicular driving information, such as position, speed,\nand acceleration rate, ITSAS produces advisory speed information by taking into consideration the\ntraffic signal changes at a downstream intersection. The advisory speed information includes not only\nan optimal speed range updated every 300-ft for individual drivers but also a descriptive message to\nwarn drivers stop to ensure safety at the downstream intersection. Unlike other similar Connected\nVehicles applications for intersection management, ITSAS does not require Roadside Equipment\n(RSE) to disseminate the advisory speed information as it is designed to exploit commercial cellular\nnetwork service (i.e., 3G and 4G-LTE). Thus, ITSAS can be easily plugged into existing traffic control\nmanagement system to rapidly conduct its implementation without significant additional cost.\nThis research presents the field evaluations of ITSAS on a signalized corridor in New Jersey, which\ndiscovered significant travel time savings for the equipped vehicle
