Research on Travel Mode Discrimination Based on Cell Phone GPS Trajectory
摘要
Abstract
Extracting Cell phone GPS travel trajectory data,analyze that characteristics of travel trajectory of different travel modes.Three variables,the average speed of trajectory,the speed range and the probability that the trajectory below 20 quantile of speed fall into the bus stop area are selected as the discriminant variables for determining the travel mode.Fisher method and Bayes method are respectively used to construct the travel mode discriminant function,and the discriminant variable values are substituted into the discriminant function to judge the travel mode of the cell phone GPS trajectory,which verifies the effect of the discriminant analysis method in determining the travel mode of the cell phone GPS trajectory,and provides a certain reference for analyzing traffic problems by using the cell phone GPS trajectory big data.关键词
