The data port 599 accumulated signals from the device 500 may be used to detect the presence of a behind-the-road vehicle approaching said preceding vehicle may be by the device 500 for making contact with said behind-the-road vehicle by a vehicle-to-vehicle communication device. The data port 599 accumulated signals from the device 500 may be used to detect the presence of a behind-the-road vehicle approaching said preceding vehicle may be by the device 500 for obtaining information about the following vehicle by a vehicle infrastructure communication device. The data port 599 accumulated signals can be from the device 500 be used to determine a relative speed of said vehicles. The data port 599 accumulated signals can be from the device 500 be used to take action if the relative speed of said vehicles indicates a risk of collision to prevent said collision. The data port 599 accumulated signals from the device 500 be used to take action when the relative speed of said vehicles indicates a risk of collision to prevent said collision may be imposed by the device 500 for obtaining information about said risk by one of said communication devices in the preceding vehicle.

Portions of the procedures described herein may be used by the facility 500 using the computing device 510 be performed, which in the separate memory 560 or in the read / write memory 550 stored program executes. If the device 500 executing the program, parts of the procedures described in this document are carried out.
