| 摘 要： | 基于合流区交通流作用机理，从时间和空间层面梳理了高速公路入口匝道通行能力的影响因素。结合集装箱卡车混合交通流的合流特征，通过实际观测数据对Vissim仿真参数进行了标定，进而定量分析了主路流量、主路及匝道交通组成、加速车道长度对入口匝道通行能力的影响。研究成果可以为集装箱卡车交通较多的高速公路入口匝道管理、合流区道路设计提供参考依据。

| Abstract: | The factors which influence the expressway on-ramp capacity are analyzed from the perspective of time-space based on the merging process.Field data are collected to calibrate the Vissim simulation parameters based on container truck traffic merging characteristics.Then,the effect of the on-ramp capacity is simulated and quantitatively analyzed,due to the major road flow and traffic composition,the ramp traffic composition and the length of the acceleration lane.The analysis results can provide references fo... |
