Dynamic OD Expansion Method Based on Mobile Phone Location

Because of the shortcomings such as intensive labors, low accuracy data, and no-timely information of the manual survey methods for collecting dynamic origin-destinations, a method for expanding dynamic origin-destination data based on mobile phone locations from samples to collectivities is designed according to the status with a large number of users and advanced location technology on mobile phone, and then the method is verified with simulation data. The results show that the method put forward can produce origin-destination data with high quality, which will provide reliable decision information for traffic management.
