Abstract
Systems and methods for requesting modification of traffic flow control systems that combine satellite position navigation systems and dead reckoning technology with secure radio communications to accurately report a vehicle's real-time location and estimated arrival times at a series of signal lights within a traffic grid or at a distant signal light, while enabling signal controllers to accommodate priority requests from these vehicles, allowing for these vehicles to maintain a fixed schedule with minimal interruption to other grid traffic.
