基于旅行时间分布的客流清分模型

摘要

Under the condition of urban rail transit network formation with "one-ticket transfer" and investment diversification, the fare clearing center (FCC) needs to establish a fair and impartial mechanism to solve the problems of ticket fare clearing. A method is proposed to calculate the proportion of passengers on each path based on passenger traveling time distribution. According to the entry and exit time records in traffic system, the travel time distribution of all the passengers within a period of time can be obtained between each pair of origin-destination ( OD) and the proportion of passengers on each path in this period is also estimated. Numerical simulation method is used to generate travel time data in a pair of OD, and then the passenger proportion is computed based on these data. The simulation results show that it is accurate even with extremely small necessary time-difference between two paths. This dynamic method accurately reflects the actual distribution of passenger flow.%在城市轨道交通的线路网络形成、实行一票换乘并伴随投资主体多元化时,需要建立公平公正的票务清分机制,本文提出一个基于乘客旅行实际时间分布计算各路径上乘客比例的新方法.根据交通卡中的进出站的时间记录,计算出在一段时间内在一对出入站之间完成旅行的所有乘客的时间分布,以这个分布为依据计算在这段时间里各路径上的乘客比例.采用数值模拟的方法在一对有两条有效路径的出入站间产生乘客旅行时间的数据,然后根据这些数据进行客流比例计算.结果表明,即使两条路径的运营时间差异很小也能实现较准确的比例划分,这种动态计算客流分布的方法能更准确地反映实际客流分布.
