摘要
城市快速路立交改造中普遍存在交织运行的车辆冲突问题.本文从互通式立交交织区已知理论公式中,固定相关已知参数,探讨未知参数L(交织区段长度)和N(交织区段车道数)的关系.同时,从实际调查数据入手,对交织数据进行具体分析,求得大致L和N的最优解,为提高城市快速路运行效率提供理论依据和实践支撑.
Abstract
The problem of vehicle conflict in weaving operation is common in the reconstruction of urban expressway interchange.In this paper,the relationship between unknown parameters L(length of weaving section)and N(number of lanes in weaving section)is discussed by fixing the relevant known parameters from the known theoretical formula of weaving section of interchange.At the same time,starting from the actual survey data,through the specific analysis of the interlaced data,the optimal solution of L and N is obtained,providing theoretical basis and practical support for improving the operational efficiency of urban expressways.
