Research on Expressway Vehicle Detection System Based on Gantry System
With the rapid development of China's expressway construction,expressway mileage and the number of vehicles are growing continuously.In order to realize the intelligent and digital operation of expressways,and make vehicles pass orderly,efficiently and safely,the vehicle information acquisition devices are gradually added to the new and reconstructed expressways.This paper proposes a vehicle detection system based on ETC gantry system,analyzes the operation principle of vehicle detection system,and carries out practical application.Through real-time data acquisition of vehicles passing through the gantry,the speed,vehicle type,quality and other physical indicators of passing vehicles can be more accurately grasped,so as to accurately monitor vehicle status and running trajectory.
