Based on the traffic flow data detected by Remote Traffic Microwave System of the urban expressway, after integrating detected data of two minutes into data of five minutes, and transforming detected occupancy information to density parameter by using the average vehicle length index, a comparative analysis to the traffic flow operation time-space characteristics for different time-sessions, different lanes and different detectors will be studied. And by the Van-Aerde model, the traffic model parameters of different lanes and sections will be calibrated for further study. The research can provide scientific basis and data support for the layout, design, operation, management and evaluation of expressway.
