| 摘 要： | 为了解决多车道高速公路分流交织区由于车道数增加、交通流量增加、标志设置不合理等原因存在的诸多安全问题，在分析多车道高速公路分流交织区存在的问题和总结现有多车道高速公路断面形式（整体式断面、客货分离式断面、主辅分离式断面）的基础上，提出多车道高速公路分流交织区的交通组织形式及其优缺点。总结了多位学者对多车道高速公路分流交织区处的运行车速、通行能力及安全特性和冲突特性的研究，并在此基础上，提出了多车道高速公路分流交织区处的交通管理（车道管理和车速管理）及诱导设施（同向分隔带、标志标线）的优化意见。所提出的交通管理及诱导设施的优化方案可以显著提高多车道高速公路分流交织区的安全性及其运行效率。

| Abstract: | Many safety problems exist in the interleaving area of multi-lane expressways due to increased lanes and traffic flow and the unreasonable setting of signs. The traffic organization form with its advantages and disadvantages of the interleaving area of multi-lane expressways is proposed by analyzing the problems in the interleaving area of multi-lane expressways and the forms of existing multi-lane expressways(integrated section, passenger-and-cargo separated sections, and main and auxiliary separated sections). According to the operating speed, capacity, safety characteristics, and conflict characteristics of the multi-lane expressway diversion and weaving area, optimized suggestions on traffic management(lane and speed managements)and guidance facilities(same direction separation zone and marking)at the diverging and weaving areas of multi-lane expressways are put forward. The proposed optimization opinions on traffic management and guidance facilities can significantly improve the safety of the interleaving area of multi-lane expressways as well as its operation. |
