Method for conveying driving conditions and using the conveyed driving conditions for vehicular control includes generating information about a travel surface or an environment around the travel surface using sensors fixed in position relative to the travel surface. Each sensor includes a measuring or detecting component that measures or detects a property or condition of the travel surface or the environment around the travel surface. A communication of the information generated by that sensor to a vehicle or its occupant is initiated only when that vehicle is within the set distance from a sensor. Operation of a display, navigation, control and/or guidance system in that vehicle is caused to change from an existing operating state to one of several different operating states as a result of reception of the communication from the sensor.

The method of claim 1, wherein the change in operation of at least one of the display, navigation, control and guidance system in the vehicle determined to be within the set distance from the one of the sensors by the proximity notification system is presentation of a visual indication of content of the generated information on a map shown on a display of the display system such that the visual indication of the content of the generated information is placed on the map as the vehicle approaches the position of the one of the sensors. 3. The method of claim 1, wherein each of the sensors is configured to include an identification code indicative of its position with the generated information. 4. The method of claim 1, wherein the sensors are coupled to a telecommunications and data network, further comprising transmitting the information generated by the one of the sensors, initiated only when the vehicle is determined to be within the set distance from the one of the sensors, to the vehicle determined to be within the set distance from the one of the sensors by the proximity notification system, using the telecommunications and data network. 5. The method of claim 1, wherein the sensors are coupled to a telecommunications and data network, further comprising: receiving, at a remote location, the information generated by each of the sensors,the step of directing, using the communication system, the information generated by the one of the sensors to the vehicle determined to be within the set distance from the one of the sensors by the proximity notification system comprising transmitting, from the remote location, the information generated by any of the sensors to the vehicle determined to be within the set distance from that sensor by the proximity notification system using the telecommunications and data network when the vehicle is determined to be within the set distance from that sensor by the proximity notification system. 6. The method of claim 1, wherein the step of determining, using the proximity notification system, when the vehicle is within the set distance from any of the sensors comprises analyzing, using a processor, the current position of the vehicle relative to the fixed position of each of the sensors to determine if a difference between the current position of the vehicle and the fixed position of any of the sensors is less than the set distance. 7. The method of claim 1, wherein the sensors are coupled to a dedicated short range communications network, further comprising transmitting the information generated by the one of the sensors, initiated only when the vehicle is determined to be within the set distance from the one of the sensors, to the vehicle determined to be within the set distance from the one of the sensors by the proximity notification system, using the dedicated short range communications network. 8. The method of claim 1, wherein the information generated by the one of the sensors is directed as a wireless transmission intended for reception by a vehicular navigation system in the vehicle determined to be within the set distance from the one of the sensors by the proximity notification system, whereby operation of the navigation system is changed from the existing operating state to one of the plurality of different operating states as a result of reception of the wireless transmission. 9. The method of claim 1, wherein the step of determining, using the proximity notification system, when the vehicle is within the set distance from any of the sensors comprises using a proximity sensor coupled to each of the sensors that senses the vehicle when the vehicle is within the set distance from the proximity sensor and does not sense the vehicle when the vehicle is beyond the set distance from the proximity sensor. 10. The method of claim 9, wherein the proximity sensor uses a thermal system, a sound sensing system, an optic system, radar or laser radar (lidar) to analyze proximity of the vehicle. 11. The method of claim 9, wherein the proximity sensor comprises a camera or other optical sensor that obtains images, the step of determining, using the proximity notification system, when the vehicle is within the set distance from any of the sensors comprising analyzing images obtained by the camera or other optical sensor to assess a distance between the proximity sensor and the vehicle. 12. The method of claim 1, wherein the step of determining, using the proximity notification system, when the vehicle is within the set distance from any of the sensors comprises: providing a processor at a location separate and apart from the sensors and the vehicle with the current position of the vehicle and the fixed position of each of the sensors; anddetermining at the processor, from the provided current position of the vehicle and fixed position of each of the sensors, if a difference between the current position of the vehicle and the fixed position of any of the sensors is less than the set distance. 13.
