Abstract
A system and method for giving priority to and navigating emergency vehicles and any other priority vehicles (such as transit vehicles, roadway maintenance vehicles, eco-friendly vehicles, and other vehicles for which it is desired to give priority treatment at traffic signals) by controlling vehicle traffic signals to allow safe and efficient passage of these priority vehicles. The system includes a software-based system and method for providing dynamic vehicle routing, navigation and traffic signal preemption and priority.
Claims20
An in-vehicle navigation and preemption system comprising:
- a vehicle navigation system for calculating a route to a set target destination between a repeatedly determined current vehicle position and a target destination;
- and
- a preemption request module that generates a preemption request for at least a next upcoming traffic signal based on the determined current vehicle position and a calculated estimated time of arrival at the traffic signal determined along the route calculated by the vehicle navigation system, the preemption request taking into consideration ingress approach data and egress approach data for the vehicle at the traffic signal.
A method for vehicle navigation and traffic signal preemption, comprising the following steps:
- receiving input of a target destination;
- repeatedly determining a current vehicle position;
- calculating a route for the vehicle;
- identifying traffic signal positions along the calculated route;
- calculating an estimated time of arrival for at least a next upcoming traffic signal along the route;
- generating a preemption request for at least the next upcoming traffic signal based on the determined current vehicle position and the calculated estimated time of arrival, the preemption request taking into consideration ingress approach data and egress approach data for the vehicle at the traffic signal.
