新元高速施工期双向4车道的混合流仿真研究
A Simulation Study on Mixed Flow of Two-way Four Lanes During Construction of Xinyuan Expressway
摘要
Abstract
Xinyuan Expressway currently bears a relatively large traffic load,resulting in poor service levels and frequent congestion,and needs to be modified and expanded.During the construction process,in order to reduce the impact of mixed passenger and freight traffic on the efficiency of traffic flow.Using micro simulation methods to simulate the traffic scenarios of passenger and freight vehicles during the construction period,grasp the characteristics of traffic operation,and provide theoretical basis for the formulation of traffic organization plans during the construction period.Based on the cellular automata model theory and Matlab language,a two-way four-lane basic road section model based on the current ground-level during the construction period of Xinyuan Expressway is established,the influence of trucks on the traffic flow in time and space,flow,average speed and average number of lane changes is analyzed.At the same time,the impact on traffic flow is analyzed when the lanes are divided into functions.Through the conclusion,the management suggestions for the current ground-level traffic-ensured plan during the construction period of Xinyuan Expressway are put forward.关键词
