基于跟驰模型、换道模型的快速路立交微改善研究——以竹叶山立交为例

Based on the Following Model,Lane Changing Model Expressway Interchange to Improve the Micro——A Case Study of Interchange Zhuyeshan

提升城市交通系统运行效率的关键就是改善快速路立交,本次研究分别从宏观、中观、微观分析了立交主要拥堵成因,从空间转移、时间转移、综合保障三个方面提出交通微治理措施,介绍了VISSIM仿真的流程及评价指标体系,对快速路跟驰换道模型的特征进行了研究。最后以竹叶山立交为例进行实例仿真分析,结果显示改善措施有效,路网改善后整体运行效率提升。

The improvement of urban expressway interchanges is the key to improving the operation efficiency of the urban transportation system.This research analyzes the main congestion causes of interchanges from the macro,meso,and micro levels,and proposes micro-traffic governance measures from three aspects:space transfer,time transfer,and comprehensive security,Introduced the VISSIM simulation process and evaluation index system,and studied the characteristics of expressway car following model and lane changing model.Finally,a case simulation analysis with Zhuyeshan Interchange as an example shows that the improvement measures are effective,and the overall operation efficiency is improved after the road network is improved.
