北京地铁乘客旅行时间分布规律与可靠性研究

With the rapid development of China's urban rail transit, passengers are more sensitive to the change of travel time. In order to better meet the requirements of the passengers and improve the competitiveness of urban rail transit in the traffic system, we need to master the distribution of the travel time of the passengers in the urban rail transit and the reliability of the travel time. Using the data provided by the automatic fare collection system(AFC) of Beijing metro. First of all, the distribution of the passengers' travel time is studied, and the K-S single sample test is used to verify the passengers' travel time in Dongzhimen to Beijing Railway Station to obey the Gamma distribution and lognormal distribution. Secondly, based on the distribution of travel time, through the following five indicators: plan travel time (PT), plans travel time index (PTI), reliability buffer time (RBT), reliability buffer time index (RBTI) and the extra reliability buffer time (ERBT), The influence of the passenger flow scale, transport distance, transfer number and operation fault on the reliability of the travel time were studied.
