| 摘 要： | 传统的排队论理论单纯使用需求量和通行能力关系推算排队长度,由于其未考虑车流波动的影响,从而使估算结果与实际出入很大。现用车流波动理论分析发生交通事故后路段上车辆排队的形成与消散过程,推导出估算排队长度与消散时间的公式,并通过算例说明根据估算值提前分流,可提高道路的通行能力。 |
| 关 键 词： | 交通事故 车流波动 排队长度 消散时间 车辆 |

| Abstract: | The traditional Queuing Theory calculates the queue length only based on demand and through capacity. Since it ignores the influence of vehicle flow fluctuating, the calculation result differs a lot from the actuality. Now the vehicle flow fluctuating theory is employed to analyze the formation of vehicle queue as well as the dispersing process after accident and to deduce the calculation formula for queue length and dispersing time. With a calculation case, the paper states that the through capacity of road can be improved with aforehand diffluence according to calculation. |
| Keywords: | accident vehicle flow fluctuating queue length dispersing time vehicle |
