Abstract:In view of the urban road traffic system’s temporal and spatial distribution is severe unevenly

and we cannot predict the situation of the roads

it is easily to lead to traffic jam.In order to solve the problem

we could build the system of vehicle trips in urban road traffic

which combined with pattern recognize technique nique and data mining method

and based on the massive video data collected by the urban traffic monitoring sysem.The system can offer effective data support to optimizing traffic signal timing furtherly

regulating traffic flow

improving traffic management efficiency and road traffic resource utilization

eventually improve traffic congestion.
