快速公交的载客半放车调度方法

为解决快速公交系统中出现的串车和大间隔现象,提升系统通行能力,对影响系统通行能力的因素进行了分析研究.研究表明,在高峰期影响系统通行能力的关键因素是车辆的停靠时间,而停靠时间中乘客登车时间的占比最大,波动性也最大.借鉴放车调度和载客放车调度,提出了载客半放车的调度方法,通过对上客流的适时截止来控制车辆停靠时间从而降低车辆满载率.分析表明,该方法能有效控制高峰期车辆停靠时间,提升系统通行能力,并为缩小发车间隔、发掘系统运能潜力创造了条件.

Half Loaded Deadheading Scheduling for Bus Rapid Transit

To resolve the problem of bus-string and big-interval in BRT, and to enhance the system capacity, an analysis was made on the factors affecting the system capacity. Studies have shown that the vehicle＇s dwelling time is the key factor for system capacity in rush hour. Passenger boarding time takes the largest proportion of dwelling time and its volatility. A loaded half deadheading scheduling is then proposed taking reference to deadheading scheduling and loaded deadheading scheduling. The method helps reduce dwelling time and the load rate by cutting off boarding stream timely. Based on the analysis, the method can effectively control the vehicle＇s dwelling time in rush hour, and improve the system capacity, thus paving the way for shortened headway and increased system capacity.
