| Abstract: | Urban traffic situation information is the basis of effective traffic guidance and traffic control. It is usually expressed by average speed and average travel time of the vehicles on the road. On the basis of the error analysis of the algorithms based on average speed and average travel time, this article promoted the urban traffic situation calculation methods based on probe vehicle data. And experiments were made based on probe vehicle data provided by the taxi management system of Guangzhou, China, combined with the data by the method of vehicle license timing and vehicle following. The results proved that the method is quite effective and practical. |
