The microwave vehicle detection can obtain real-time conditions of road traffic flow fast, accurate and convenient. In this study, we took the expressway traffic flow in Chengdu as the research object, collecting real-time data of traffic flow, speed and vehicle density to analyses the relationship among Q, V, K graphically. Finally the service level in different lanes and speed in the Third Ring Road were evaluated through Q, V, K data calculations and analysis in Chengdu’s expressway at the traffic peak time.
