基于FCD轨迹数据挖掘的城市出行特征分析

Analysis of Urban Travel Characteristics Based on FCD Trajectory Data Mining

随着科技的进步,GPS系统的发展,交通工具的广泛使用,关于浮动车辆移动轨迹的研究逐渐深入。出租车是城市中便捷性、普及性都很高的类型,基于出租车移动轨迹挖掘城市居民的出行特征具有可行性。研究城市居民出行特征,发现出行热点时间段、出行规律等,对于出租车运营、城市建设都有重要的意义。文中将主要运用Matlab等软件,结合算法,对出租车的轨迹数据点进行一系列的计算,得到数据图表,进行规律挖掘,同时研究城市居民出行的时间特征和空间特征,将粗略处理的数据与详细处理的数据放在一起进行参考,得出更加准确的出租车轨迹数据特征,从而得到城市居民出行特征。

With the advancement of technology,the development of GPS system and the widespread use of vehicles,the research on the trajectory of floating vehicles has been gradually deepened.Taxi is a type with high convenience and popularity in the city,so it is feasible to excavate the travel characteristics of urban residents based on taxi movement trajectory.It is of great significance for taxi operation and urban construction to study the travel characteristics of urban residents and find out the rush hour and travel rules.It will mainly use Matlab,ArcGIS and other software,combined with algorithms,to perform a series of calculations on the trajectory data points of taxis,get data charts,and conduct regular mining to study the travel characteristics of urban residents.This article will study the temporal and spatial characteristics of urban residents travel,and put the rough and detailed processed data together for reference,so as to obtain more accurate taxi trajectory data characteristics,which can be pushed to the urban residents travel characteristics.
