Method and arrangement for setting a speed limit for vehicle travelling on a road includes monitoring conditions of the road, determining a speed limit for travel of vehicles on the road based on the monitored conditions, and transmitting the determined speed limit to the vehicles to thereby notify operators of the vehicles of the determined speed limit. Monitoring conditions of the road may entail monitoring weather conditions around the road, monitoring visibility for operators of the vehicles on the roads, monitoring traffic on the road, monitoring accidents on the road or emergency situations of vehicles on the road and/or monitoring the speed of vehicles travelling on the road and a distance between adjacent vehicles.

1. A navigation system for use in a vehicle, the navigation system comprising: at least one position determining processor configured to determine a current location of the vehicle;a processor configured to obtain a speed limit for the roadway on which the vehicle is traveling based on the current location of the vehicle determined by the at least one position determining processor; anda navigation display configured to show a map of a roadway on which the vehicle is traveling based on the current location of the vehicle determined by the at least one position determining processor,wherein the navigation display is further configured to show the speed limit for the roadway on which the vehicle is traveling as obtained by the processor, andwherein the navigation system is configured to alert an occupant of the vehicle when the speed of the vehicle exceeds the speed limit for the roadway on which the vehicle is traveling. 2. The navigation system of claim 1, wherein the navigation system is configured to audibly alert the occupant of the vehicle. 3. The navigation system of claim 1, wherein the navigation system is configured to alert the occupant of the vehicle by displaying an icon on the navigation display. 4. The navigation system of claim 1, wherein the navigation system is configured to alert the occupant of the vehicle by displaying an icon on a heads up display device for projecting a display in a field of view of the occupant of the vehicle. 5. The navigation system of claim 1, further comprising a heads up display device configured to project a display in a field of view of an occupant of the vehicle, wherein the projected display includes at least one of the speed limit and the map of the roadway. 6. The system according to claim 1, wherein the at least one position determining processor and the processor are implemented as a single processor. 7. The system according to claim 6, wherein the single processor is a general purpose processor. 8. The system according to claim 1, wherein the at least one position determining processor comprises a GPS processor. 9. The system according to claim 8, wherein the GPS processor comprises a GPS receiver. 10. The system according to claim 1, wherein the processor comprises a general purpose processor. 11. The system according to claim 1, wherein the current location of the vehicle is determined based on satellite information. 12. The system according to claim 1, wherein the current location of the vehicle is determined based on satellite information and ground network information. 13. The system according to claim 12, wherein the ground network information comprises differential correction information. 14. A method for providing speed limit information on a navigation system of a vehicle, the method comprising: determining, by at least a first processor, a current location of the vehicle;obtaining, by at least a second processor, a speed limit for the roadway on which the vehicle is traveling based on the current location of the vehicle determined by the at least the first processor; andalerting an occupant of the vehicle when the speed of the vehicle exceeds the speed limit for the roadway, on which the vehicle is traveling. 15. The method of claim 14, wherein the alerting includes audibly alerting the occupant of the vehicle. 16. The method of claim 14, wherein the alerting includes displaying an icon on a navigation display. 17. The method of claim 14, wherein the alerting includes displaying an icon on a heads up display device for projecting a display in a field of view of the occupant of the vehicle. 18. The method of claim 14 further comprising: projecting a display in a field of view of the occupant of the vehicle on a heads up display device, wherein the projected display includes at least one of the speed limit and the map of the roadway. 19. The method according to claim 14, wherein the at least a first processor and the at least a second processor are implemented as a single processor. 20. The method according to claim 19, wherein the single processor is a general purpose processor. 21. The method according to claim 14, wherein the at least a first processor comprises a GPS processor. 22. The method according to claim 21, wherein the GPS processor comprises a GPS receiver. 23. The method according to claim 14, wherein the at least a second processor comprises a general purpose processor. 24. The method according to claim 14, wherein the current location of the vehicle is determined based on satellite information. 25. The method according to claim 14, wherein the current location of the vehicle is determined based on satellite information and ground network information. 26. The method according to claim 25, wherein the ground network information comprises differential correction information. 27. A navigation system for use in a vehicle, the navigation system comprising: at least one position determining processor configured to determine a current location of the vehicle;a processor configured to obtain a speed limit for a roadway on which the vehicle is traveling based on the current location of the vehicle determined by the at least one position determining processor; anda navigation display configured to show a map of the roadway on which the vehicle is traveling based on the current location of the vehicle determined by the at least one position determining processor,wherein the navigation display is further configured to display the speed limit for the roadway on which the vehicle is traveling as obtained by the processor, andwherein the navigation system is configured to alert an occupant of the vehicle when the speed of the vehicle exceeds the speed limit for the roadway on which the vehicle is traveling. 28. The navigation system of claim 27, wherein the navigation system is configured to visually alert the occupant of the vehicle. 29. The navigation system of claim 27, further comprising a heads up display device configured to project a display in a field of view of the occupant of the vehicle, wherein the projected display includes at least one of the speed limit, a visual alert, and the map of the roadway. 30. The navigation system of claim 27, wherein the navigation system is configured to alert the occupant of the vehicle when the speed of the vehicle exceeds the speed limit for the roadway on which the vehicle is traveling by a predetermined threshold.
