| Abstract: | To analyze the traffic dynamic conditions and evaluate traffic management effet,we presented the process of the modeling of urban dynamic traffic network model and summarized four key technical issues which were dynamic OD estimation,calibration of traffic characteristic parameters,dynamic traffic assignment options,and calibration of scenario parameters.On such basis,we visually illustrated the main functions of the model using test results of the virtual networks.Finally,we used INTEGRATION to develop the dynamic traffic model of the traffic network of Beijing and evaluated the effects of ramp metering and accident responding schemes. |
