基于时空分析的地图匹配算法研究
Map-matching algorithm research based on spatio-temporal analysis
摘要
Abstract
Considering the large volumes of floating car data,the lower real-time and map matching rate of map matching algo-rithm in current urban transportation,this paper proposed a map-matching algorithm based on spatio-temporal analysis.On the basis of grid index building for urban road network,this algorithm considered the spatial geometric,topological structures info of the road network and the impact on the selection of GPS point’s projection,which greatly enhanced the matching efficiency and improved the matching accuracy.The experiment proves that this algorithm can meet the requirement of real-time performance and accuracy of floating car map matching in the practical application.关键词
