随着城市的快速发展,道路拥堵、打车难等问题越来越突出,严重影响了居民的出行效率和生活质量。出租车GPS数据,在一定程度上包含了部分居民出行行为的丰富信息。考虑到出租车载客事件发生于一维道路网络空间,本文提出对出租车上下客事件所在路段进行分析,得到不同时段居民出行的热门路段和区域,分析居民出行时空分布特征,有助于了解交通现状和居民出行需求,提高城市对居民出行活动的服务水平。

On the Spatial and Temporal Distribution of Resident Trip Based on Taxi GPS Data

With the rapid development of the city, the problems of road congestion and the difficulty in hailing a taxi are becoming more and more serious, which seriously affects people's pursuit of travel efficiency and quality of life. Taxi GPS data contains abundant information about travel behavior of residents. Considering that the taxi carrying passengers events usually occur in 1D road network space, this paper puts forward the analysis of the road sections where the taxi pick-up and drop-off events occur and obtains the popular road sections and regions of the resident trip at different times, and analyzes the spatial and temporal distribution of the resi-dent trip, which can help to understand the traffic situation and residents' travel demand, and improve the service level of residents in city.
