摘要
车辆时空分布规律的研究对于改善现今交通拥堵情况拥有重要意义,其中出租车作为公共交通体系中的一支,研究其时空分布规律显得尤为重要。以南京市出租车GPS数据为研究对象,利用SQL数据库软件,筛选出晚高峰时间段6组数据,并利用Power map制作热图,通过可视化分析,得出了南京市热点区域在建宁路、龙蟠中路、内环西线、中心路段、应天大街高架呈现随时间迁移逐渐扩散收缩再扩散的分布特征。
The study of the temporal and spatial distribution of vehicles is of great significance to improve the current traffic congestion situation.Among them,taxis are a part of the public transportation system.It is particularly important to study the temporal and spatial distribution of vehicles.This article takes Nanjing taxi GPS data as the research object,uses SQL database software to screen out six sets of data during the late peak period,and uses Power map to make a heat map.Through visual analysis,it is concluded that Nanjing's hotspot area is on Jianning Road,Longyao middle Road,the inner ring west line,the central section,and the Yingtian Avenue viaduct show a distribution characteristic that gradually diffuses,shrinks,and re-diffuses with time.
