Abstract

An information system and method provides information to an operator of an emergency response vehicle. A destination location and a current position of the motor vehicle are established. A planned route as a function of the destination location and the current position is established and communicated to at least one traffic control system, an alternate route is established as a function of a factor which may delay travel over the planned route, the destination location, and the new current position and a modified route plan is communicated to at least one traffic control system. The traffic control received positional data on the vehicle and controls the traffic control devices under its management to expedite the transit of the emergency vehicle.

Claims

1. An information system for providing information to an operator of an emergency response vehicle, comprising:

an input system for establishing a destination location of the emergency response vehicle;

a positioning system for establishing a current position of the emergency response vehicle;

a routing system on board the emergency response vehicle in two-way communication with at least one traffic control system via a two-way communications network, the at least one traffic control system being external to the emergency response vehicle, the routing system for automatically determining, without operator input, a planned route as a function of the destination location and the current position, sending the planned route to the at least one traffic control system using the two-way communications network and for receiving information relating to a factor, established as a function of the planned route, which may delay travel over the planned route, establishing a new current position, responsively determining if the planned route needs to be modified, and automatically determining, an alternate route as a function of the factor, the destination location, and the new current position if the planned route needs to be modified and sending the modified route plan to the at least one traffic control system over the two-way communications network.

2. An information system, as forth in claim 1, the communications network being a two-way network optionally supplemented by one way RFID points for transmitting vehicle data to the one or more traffic control systems.

3. An information system, as set forth in claim 2, the vehicle data including the current position of the emergency response vehicle, progress of the emergency response vehicle along the planned route, and vehicle operational characteristics.

4. An information system, as set forth in claim 2, wherein the routing system coordinates the planned route and/or the alternative routes to the at least one traffic control system.

5. An information system, as set forth in claim 4, the one or more traffic control systems including at least one traffic control signal, the routing system sending a request to the at least one of the traffic control system to control the at least one traffic control signal to minimize any impact of other traffic traveling along the planned route or the alternative route.

6. An information system, as set forth in claim 2, the at least one traffic control system for monitoring the position of the emergency response vehicle along the planned or alternative route to alert, in a timely fashion, vehicular and/or pedestrian traffic of the approaching emergency response vehicle.

7. An information system, as set forth in claim 6, wherein the traffic control system performs the alert using an audible alarm and/or an visual signal and/or other signal to be received by an appropriate device in other vehicles.

8. An information system, as forth in claim 2, the traffic control system including a railroad crossing system and a water way bridge opening system, the traffic control system monitoring the position of the motor vehicle along the planned or alternative route and coordinating with the railroad crossing and water way bridge opening systems.

9. An information system, as set forth in claim 8, the railroad crossing and water way bridge opening system includes one or more bridges and/or one or more railroad crossing.

10. An information system, as set forth in claim 8, information system including a railroad crossing and water way bridge opening system, one or more traffic control systems, the communications network being a two-way network for transmitting vehicle data to the one or more traffic control systems.

11. An information system, as set forth in claim 1, further comprising a preference device containing preference information related to the operator of the emergency response vehicle, the routing system for establishing the planned route and/or alternate route as a function of the preference information.

12. An information system, as set forth in claim 1, the input system comprising a user interface, the system further comprising a communication system for communicating information to the operator.

13. An information system, as set forth in claim 12, the communication system including a display coupled to the routing system for graphically and/or textually displaying the planned route and/or the alternate route to the operator.

14. An information system, as set forth in claim 1, the received information related to the factor including a plurality of parameters which may affect the estimated time of arrival.

15. An information system, as set forth in claim 14, the plurality of parameters including at least one of location of factor, vector coordinates of factor, radial impact of factor, or gradient impact of factor.

16. An information system, as set forth in claim 1, the routing system for monitoring the current position of the emergency response vehicle, determining if the operator has not followed the planned route, and responsively modifying the planned route as a function of the position of the emergency response vehicle and sending the modified route plan to the at least one traffic control system.

17. A computer based method for providing information to an operator of a emergency response vehicle, comprising:

establishing a destination location of the emergency response vehicle;

establishing a current position of the emergency response vehicle;

automatically determining a planned route as a function of the destination location and the current position, without operator input;

sending the planned route to at least one traffic control system over a two way communications network, the at least one traffic control system being external to the emergency response vehicle;

receiving information from the at least one traffic control system related to a factor, established as a function of the planned route, which may delay travel over the planned route; and

,

establishing a new current position and automatically determining an alternate route as a function of the received information, the destination location, and the new current position, without operator input, and sending the alternate route plan to the at least one traffic control system.

18. The method, as set forth in claim 17, including the step of communicating vehicle data to one or more traffic control systems.

19. The method, as set forth in claim 18, the vehicle data including the current position of the emergency response vehicle, progress of the emergency response vehicle along the planned route, and vehicle operational characteristics.

20. The method, as set forth in claim 17, including the step of coordinating the planned route and/or the alternative routes with the at least one traffic control system.

21. The method, as set forth in claim 20, including the step of monitoring the position of the emergency response vehicle along the planned or alternative route and alerting, in a timely fashion, vehicular and/or pedestrian traffic of the approaching emergency response vehicle.

22. The method, as set forth in claim 21, wherein the alert is an audible alarm and/or an visual signal and/or other signal to be received by an appropriate device in other vehicles.

23. The method, as set forth in claim 17, the at least one traffic control system including at least one traffic control signal, the method including the step of sending a request to the at least one of the traffic control system to control the at least one traffic control signal to minimize any impact of other traffic traveling along the planned route or the alternative route.

24. The method, as forth in claim 17, the traffic control system including a railroad crossing and water way bridge opening system, including the step of monitoring the position of the emergency response vehicle along the planned or alternative route and coordinating the railroad crossing and water way bridge opening system.
