曲率积分约束的GPS浮动车地图匹配方法

摘要

提出了以轨迹曲线的曲率积分值作为地图匹配特征的匹配方法，利用轨迹曲率积分值约束前后相邻轨迹点的关联匹配，采用不同类型行驶路径以及不同采样间隔，实施了浮动车地图匹配试验，结果表明，以匹配正确率和稳定性评判，本文提出的曲率积分约束的浮动车地图匹配方法优于现有的未采用曲率特征匹配的经典浮动车地图匹配方法。%The paper presents a map‐matching method which mainly considers the curvature integral value of the curve as a map‐matching characteristic for constraining the associ ated matching between two adjacent GPS track points .Through the implementation of map matching experiments for floating car data on the different conditions of both route categories and sampling intervals ,the proposed curvature integra‐tion constrained map‐matching method could be superior to the classic floating car map matching method when evaluating them by the matching accuracy and stability .
