摘要
为了推行公交优先政策,我国一些城市采取了各种策略和措施,其中公交专用道因设置方便易行、成本低而被广泛采用.但是公交专用道的实际运用效果与其所在路段的条件有着密切关系.基于实际交通调查数据,利用仿真分析方法(VISSIM交通仿真软件),针对设置公交专用道的路段,研究其路段长度与公交专用道运行效果之间的关系.选取了路段行程时间、公交车延误、社会车辆延误和人均延误作为评价指标,对比分析了路段设置公交专用道前后这几项评价指标的变化.结果表明,在路段长度小于500米时,设置公交专用道往往会对路段的交通运行产生负面影响.
To implement bus priority policy, many major cities in China adapted various relevant strategies and measures. In which, bus-only lane is widely used with the properties of convenience and low-cost. In fact, the operational efficiency of bus-only lane is related to road conditions such as road length. By simula- tion method, the paper studies the impact of road length on efficiency of bus-only lane. It selects the travel time, bus delay, car delay, and average delay per person as the evaluating indicators. It also conducts a comparative evaluation on these indicators before and after setting of the bus-only lane. The results indicate that when the road length is less than 500 meters, the bus-only lane exerts negative impact on the road traffic operation.
