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.
