英文摘要：

Traffic information collection based on wireless location technology is a promising method of traffic information collection. With analyzing the related problems, a new traffic information collection method based on wireless location technology is put forward to face the mixed traffic condition of Chinese large cities. After illustrating the fundamentals of the method and the system architecture, the handoff point information of the mobile stations is obtained by actual experiments.Then, the distribution characteristics of the handoff points is analysed.Furthermore, in order to evaluate the effectiveness and applicability of the method, PARAMICS, a kind of microscopic simulation software, is introduced to establish a simulation environment, based on which the simulation experiments are car- ried out. The simulation results show that the proposed traffic information method based on wireless location technology can obtain relatively precise traffic information.
