Signal light priority system utilizing estimated time of arrival

摘要

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.

主权项

1. A method for requesting modification of signal light control of a traffic grid, the method comprising:
having one or more vehicles within a traffic grid, each vehicle having its own schedule with a specified scheduled arrival time at each of a plurality of specified destinations; determining the one or more vehicle's estimated time of arrival at a one of said specified destinations located within the traffic grid; requesting modification of one or more traffic light signals between said vehicle's current location and said one of said specified destinations within the traffic grid based upon the one or more vehicle's estimated time of arrival at said one of said specified destinations in order to keep each of the vehicles on schedule by arriving at said one of said specified destinations closer to said specified scheduled arrival time for that specified destination than if said modification did not occur.
