Abstract
A system and method are disclosed that make operation of an emergency vehicle safer. When an emergency vehicle is traveling to or from an emergency, a route for the emergency vehicle to travel is calculated using a navigation system. Traffic signals along the calculated route are controlled to give the emergency vehicle the right-of-way along the calculated route. In addition, data indicating the calculated route of the emergency vehicle are transmitted to other vehicles located along the calculated route. In each of these other vehicles, warnings are provided to the vehicle drivers. These warnings indicate the presence of the emergency vehicle and optionally, the expected path of travel of the emergency vehicle.

A method of operation for an emergency vehicle in a geographic region comprising:
- calculating a route for the emergency vehicle to travel to a destination in the geographic region, wherein said route is calculated with a navigation system;
- determining a position of an end user vehicle traveling within the geographic region;
- determining whether the end user vehicle is located along the calculated route of the emergency vehicle;
- if the end user vehicle is located along the calculated route of the emergency vehicle, providing information about the emergency vehicle to a driver of the end user vehicle;
- and
- if the end user vehicle is not located along the calculated route of the emergency vehicle, providing no information about the emergency vehicle to the driver of the end user vehicle.
An emergency vehicle warning system comprising:
- a navigation system that calculates a route for the emergency vehicle to travel to a destination in a geographic region;
- an end user vehicle warning system installed in an end user vehicle, said end user vehicle warning system receives data regarding the emergency vehicle;
- if the end user vehicle is located along the calculated route of the emergency vehicle, said end user vehicle warning system provides a warning to a driver of the end user vehicle;
- and
- if the end user vehicle is not located along the calculated route of the emergency vehicle, said end user vehicle warning system provides no warning to a driver of the end user vehicle.
