基于智能手机大数据的交通出行方式识别研究
Travel mode recognition based on smart phone big data
摘要
Abstract
The big data generated by smart phones can bring a lot of information for traffic investigators,this paper proposed a model based on particle swarm optimization and support vector machine to recognize different travel modes based on the smart-phone data.After analyzing the characteristics of data collected by smartphones,it proposed several feature variables for mode-ling.Further on,it used particle swarm optimization for optimizing the support vector machine model,which was trained and tested for travel mode recognition based on the empirical data in Chengdu,Sichuan province.The results indicate that, the recognition accuracy of the proposed model attains 95 .1%,is higher than that of the decision trees,back propagation neu-ral network model and the support vector machine based on grid search optimization.The time efficiency of the proposed model has good performance in urban travel mode recognition.关键词
