基于IC卡数据的公交运行延误时间特征分析

Analysis of Bus Service Delay Time Based on Data of IC Card

城市交通拥堵问题日益严重.针对高峰时段的公交延误问题,提出一种基于IC卡数据匹配公交到站时间,利用高峰时段和非高峰时段公交运行时间的差值计算公交运行延误时间的方法,并识别公交服务延误较大的地区.基于北京市IC卡数据,计算分析了北京800多条公交线路的延误时间.结果表明,进京走廊和交通集散枢纽是公交运行延误时间大、延误频繁的区域.公交运行延误时间与站点乘客数量和公交站间距离呈正相关,与距城市中心距离和路网密度无明显相关性.单位距离延迟时间与公交站间距离呈负相关.

The problem of urban traffic congestion is becoming more and more serious.Aiming at the problem of bus delays during peak hours,this paper proposes a method to match bus arrival time and calculates bus service delay time by using the difference between bus service time in peak hours and in non-peak hours based on IC card data,then identifies areas with large bus service delays.Based on the Beijing IC card data,the delay time of more than 800 bus lines in Beijing is calculated and analyzed.The results show that the corridors to Beijing and transportation hubs are areas where bus service delays are large and frequent.The delay time is positively correlated with the number of passengers at the stops and the distance between bus stops,but has no obvious correlation with the distance from the city center and the density of the road network.The delay time per unit distance is negatively correlated with the distance between bus stops.
