| 摘 要： | 分别建立了城市快速路苜蓿叶互通立交合流影响区、分流影响区、交织区的端部外侧车道交通量预测模型和车头时距分布模型,根据实测数据标定了快速路苜蓿叶互通立交各区域的通行能力模型;综合上述模型建立了苜蓿叶互通立交整体通行能力计算模型,应用该模型确定了苜蓿叶互通立交的通行能力,并应用仿真方法进行了验证。结果表明:所建立的模型为研究快速路互通立交的通行能力提供了理论基础。

| Abstract: | The traffic volume forecasting models on the outmost lane of merging influence area,diverging influence area and weaving area of the urban expressway cloverleaf interchange and the time headway distribution models at the same section were built.Based on test data,capacity models of three influence areas of cloverleaf interchange of expressway in above were calibrated.The capacity forecasting model of the whole cloverleaf interchange was built based on research outcome in above which was used to calculate th... |
