Problems solved by technology

[0003] As road detection devices interact more and more with other traffic system modules, it becomes more and more difficult to test actual scenarios, consuming more labor costs and time costs, and the cycle of product problem resolution is getting shorter and shorter. longer
[0004] In the prior art, for the development of road detection devices such as radar detectors, there is a lack of traffic flow data in actual traffic scenes as a test source, and the traffic data through artificial simulation is often quite different from the actual traffic scene, making road detection devices There is a large error in the data test
