考虑集装箱卡车影响的上匝道合流区通行能力模型

Model of the Merge Capacity under the Impact of Container Trucks Model of the Merge Capacity under the Impact of Container Trucks

摘要:

基于合流区交通流的作用机理，通过实际观测数据对VISSIM仿真参数进行标定，建立考虑集装箱卡车影响因素的上匝道合流区通行能力分析的仿真模型，进而利用仿真模型定量分析主线外侧车道流量、集卡混入率两因素对上匝道合流区通行能力的影响，得到考虑集卡影响的上匝道合流区实际通行能力回归模型，并通过实测数据进行验证。

Abstract:

Based on the traffic flow mechanism analysis and field data collection in merge area, the VISSIM simulation model is established and calibrated to analyze the merge capacity under the impact of a large number of container trucks. Then a multivariate regression model of merge capacity is constructed by taking into the consideration these two parameters, the traffic volume and the mixed rate of container trucks on shoulder lane. Finally, a case study is introduced to verify the model.
