Maintenance decision support system and method for vehicular and roadside applications
A method and system are provided in which maintenance vehicles collect information from sensors and operators, forward the collected information to a server, and, in response, receive maps and operator instructions.
1. A method, comprising:
(a) receiving over a wireless network, from a plurality of snow maintenance vehicles and by a server, a plurality of sets of collected information, each of the collected sets of information comprising a snow maintenance vehicle physical location and at least one of weather and road conditions in an area of the respective snow maintenance vehicle;
(b) processing, by the server, the received collected information, said processing comprising at least one of the steps of:
(i) providing a map associated with a physical location of a selected snow maintenance vehicle;
(ii) determining an instruction for the selected snow maintenance vehicle and/or route; and
(iii) refining a weather forecast by comparing the weather forecast with actual weather conditions in the area of the respective snow maintenance vehicle and changing the weather forecast to reflect the actual weather conditions in the area of the respective snow maintenance vehicle:
(c) providing, over the wireless network, at least one of the map, the instruction, and the weather forecast to a user, wherein the map is visually displayed to the user and wherein the instruction comprises one or more of a dispatch command, an alarm based on a temporal trend in weather conditions, an alarm based on a difference in weather conditions, an alarm based on a temporal trend in road conditions, an alarm based on a difference in road conditions, a snow plow setting, a mixture of materials to be applied to a road surface, and an amount of materials to be applied to the road surface,
2. The method of claim 1 , wherein the wireless network is a cellular network.
3. The method of claim 1 , wherein the wireless network is a radio network.
4. The method of claim 1 , wherein the user is an operator of the respective snow maintenance vehicle.
5. The method of claim 4 , wherein the instruction and the weather forecast are provided to the user orally via a radio signal.
6. The method of claim 1 , wherein the user is a supervisor not located in the respective snow maintenance vehicle.
7. The method of claim 6 , wherein the at least one of the map, the instruction, and the weather forecast are provided to the supervisor at a non-portable computer terminal.
8. The method of claim 6 , wherein the at least one of the map, the instruction and the weather forecast are provided to the supervisor at a portable computer via a wireless signal.
9. The method of claim 6 , wherein the supervisor sends the at least one of the map, the instruction and the weather forecast to the operator of the respective snow maintenance vehicle.
10. A system, comprising:
a server operable to:
(a) receive over a wireless network, from a plurality of snow maintenance vehicles and by a server, a plurality of sets of collected information, each of the collected sets of information comprising a snow maintenance vehicle physical location and at least one of weather and road conditions in an area of the respective snow maintenance vehicle;
(b) process the received collected information, said process comprising at least one of the following:
(i) to provide a map associated with a physical location of a selected snow maintenance vehicle;
(ii) to determine an instruction for the selected snow maintenance vehicle and/or route; and
(iii) to refine a weather forecast by comparing the weather forecast with actual weather conditions in the area of the respective snow maintenance vehicle and changing the weather forecast to reflect the actual weather conditions in the area of the respective snow maintenance vehicle;
(c) provide, over the wireless network, at least one of the map, the instruction and the weather forecast to a user, wherein the map is visually displayed to the user and wherein the instruction comprises one or more of a dispatch command, an alarm based on a temporal trend in weather conditions, an alarm based on a difference in weather conditions, an alarm based on a temporal trend in road conditions, an alarm based on a difference in road conditions, a snow plow setting, a mixture of materials to be applied to a road surface, and an amount of materials to be applied to the road surface.
11. The system of claim 10 , wherein the wireless network is a cellular network.
12. The system of claim 10 , wherein the wireless network is a radio network.
13. The system of claim 10 , wherein the user is an operator of the respective snow maintenance vehicle.
14. The system of claim 13 , wherein the instruction and the weather forecast are provided to the user orally via a radio signal.
15. The system of claim 10 , wherein the user is a supervisor not located in the respective snow maintenance vehicle.
16. The system of claim 15 , wherein the at least one of the map, the instruction, and the weather forecast are provided to the supervisor at a non-portable computer terminal.
17. The system of claim 15 , wherein the at least one of the map, the instruction and the weather forecast are provided to the supervisor at a portable computer via a wireless signal.
18. The system of claim 15 , wherein the supervisor sends the at least one of the map, the instruction and the weather forecast to the operator of the respective snow maintenance vehicle.
