Design and Realization of Early Warning System to Monitor Abnormal Parking on Highway

In order to reduce the malignant vehicle chain rear-end collision accidents under the circumstances of heavy fog and rain and other low-visibility conditions, this paper proposed an early-warning system based on radar positioning to monitor abnormal parking on highway. This system uses radar positioning to monitor the abnormal parking vehicles on highway and builds the network of modules by the use of UDP protocol; then the main control module analyzes and processes the signals collected by the radar and transmits the order to the early-warning light through the network, so as to prompt the rear vehicle to slow down or stop in time by the light signal in the low-visibility conditions and reduce the incidence of accidents. The results proved the effectiveness of the system.
