Abstract

This research uses video detection equipment to obtain traffic flow data, calculate the probability of secondary accidents after an accident, automatically adjust the speed limit value of expressway according to the real-time changes of road traffic flow after an accident, release the speed limit value through variable information information boards, and actively intervene in the operation of traffic flow on the expressway, so as to reduce the probability of secondary accidents and accident risk, It aims to improve traffic flow operation, reduce speed dispersion, ease traffic congestion, and improve driving safety.
