Abstract

The invention provides a vehicle-road cooperation scene test evaluation method. The method comprises the following steps: step 1, receiving road safety information sent by facilities around a road; step 2, testing network connection information around the road through a test unit; step 3, testing interaction information of surrounding vehicles through a wireless transmission test unit; step 4, testing the vehicle quantity information of the vehicle through the vehicle information testing device; and step 5, carrying out comprehensive evaluation calculation on the information in the steps 1-4.Through the above various comprehensive factors, various factors in the vehicle-road cooperation scene are comprehensively evaluated, the technical effect of high efficiency and accuracy is achieved,and industrial popularization is facilitated.

Description

technical field [0001] The invention relates to the field of traffic technology, in particular to an evaluation method for scene testing of vehicle-road coordination. Background technique [0002] With the development of Internet of Vehicles technology, concepts such as smart cars, driverless cars, self-driving cars, and vehicle-road collaboration have entered people's field of vision, making people dizzy. The existing Internet of Vehicles technology usually needs to be tested and evaluated on C-ITS (Cooperative Intelligent Transport Systems), which is a vehicle-infrastructure collaborative technology, before it is officially put on the road. Information interaction and sharing are realized through vehicle-to-vehicle and vehicle-to-road communication, so as to realize intelligent collaboration and coordination between vehicles and roadside facilities, and achieve the goals of optimizing the use of road resources, improving traffic safety, and alleviating congestion. Vehicle...
