Navigation route information for traffic management
First Claim
1. A process for determining a traffic management plan on a roadway, comprising:
- receiving information from a plurality of navigation systems located in a plurality of vehicles on the roadway, wherein, for each navigation system and each vehicle the information is indicative of a present position and a planned route of the vehicle, predicting traffic congestion based on the received information, and determining a traffic management plan based on the predicted traffic congestion.

Abstract
The present disclosure provides a traffic management system that utilizes route information provided by on board navigation systems installed in commuter vehicles to predict traffic congestion and determine appropriate traffic management procedures. Traffic management procedures include adjusting the timing of traffic signals, providing traffic updates/instructions to roadside Dynamic Message Signs (DMSs), actuating movable lane barriers, etc. The predictive traffic management capabilities provided by the present system offer an advantage over existing systems because the present system can more reliably predict when and where traffic congestion will occur and implement proactive, rather than reactive, traffic management procedures to deal with congestion before it occurs.

16. A navigation system for use in a vehicle, comprising:
-
a global positioning receiver configured to determine a present position of the vehicle;
a processor configured to determine a route between the present position of the vehicle and a destination;
a wireless transmitter configured to transmit the determined route to a traffic management system; and
a wireless receiver configured to receive traffic congestion information from the traffic management system, wherein the traffic congestion information is determined from information received from a plurality of navigation systems in each of a plurality of vehicles indicative of a present position and a planned route for each of the plurality of vehicles. - View Dependent Claims (17, 18, 19)
