摘要
以现场实测道路交通数据为基础,对VISSIM微观仿真模型进行标定及有效性检验,分析了出口通行能力的影响因素.以出口速度及流量为评价指标,研究了不同交通流量组合情况下附加车道长度的变化规律.结果表明,附加车道长度与辅路及出口流量大小有关,出口附加车道合理长度为100~120 m,条件受限时取100 m.
Based on the field survey of road traffic data,micro-simulation software VISSIM was calibrated and validated.Impacts on the capacity of exit were analyzed,and the velocity and volume of exit was utilized as evaluating indicators to study the varying laws of extra lanes in the case of different traffic flow combination.The outcome show that the length of extra lane is concerned with the traffic flow of the exit and the secondary road,and the reasonable length is recommended as 100～120 m.
