中文摘要：
结合鹤洲互通与机场互通的设计实践,应用VISSIM仿真分析了复合式立体交叉交织段长度风险,研究了交织段交通冲突的分布特性,对交织段的安全性进行了评价,重点探讨了交织段的运行车速,从而揭示了复合式立体交叉交织段安全性、车速分布及通行能力的分布规律。
英文摘要：
Combining with the design practice for Hezhou Interchange and airport interchange,the paper adopts VISSIM to simulate and analyze the length risks of the weaving section of composite overpasses,researches the distribution features of the traffic conflicts in the weaving section,evaluates the safety of the section,and explores the traffic speed of the weaving section,so as to display the distribution rule for the safety,speed distribution and traffic capacity of the composite overpasses.
