摘要：匝道接地点前方交织区是影响城市高架道路下匝道通行效率的关键，其通行能力决定着整条匝道的通行能力。在调查的基础上，论文概括了高架道路下匝道地面交织区内交通流的运行特征。基于交通工程学和移动车队理论对该交织区通行能力的计算进行了理论分析，建立相应的理论模型，在此基础上，对影响交织区通行能力的因素展开分析。

LONG Kejun¹, YANG Xiaoguang², YU Jinxiu³, et al

     Abstract: Weaving section of ramp terminal is the critical section which influences efficiency of the whole off-ramp at urban elevated expressway. Capacity at weaving section determines capacity of the whole ramp. Through field survey, the paper generalized the operating characteristic of traffic

 flow at off-ramp terminal weaving section. Base on traffic engineering and mobile platoon theory, the thesis studied the capacity of weaving section

and established theoretical model. Finally, factors influencing capacity of weaving section were studied.

     Keywords: traffic engineering, capacity, mobile platoon theory, weaving section.
