Traffic simulations are effective methods of using modem computer technology to reproduct the characteristics of actual transportation system and analyze possible responses of transportation system under a variety of conditions to find the optimal solution of the transportation problems. Traffic simulations are also effective methods of evaluating the effectiveness of various types of traffic control strategy.The traditional traffic simulations merely rely on virtual traffic data and virtual traffic control strategy . The online traffic control simulation technology proposed in this paper links up simulation system and real traffic equipment with specialized interface technology and equipments. It can reproduct real traffic areas and forecast real-time traffic conditions through collecting and managing real traffic information of vehicles and traffic signal controllers. This method overcomes the disadvantages of low accuracy, low efficiency, high cost, and uncomprehensive assessment in testing and evaluating of the existing traffic control system and provides a new test approach based on the simulation technology.This paper completes the Modules design of the online traffic control simulation system .The system includes simulation software VISSIM , traffic signal control system SCOOT and simulation control software. The simulation control software based on VISSIM can reproduct traffic areas and extract and list the information of traffic signal controllers as well as detectors. The effect of the simulation can be clear at a glance. In this paper ,a crossing named gucheng was simulated with the simulation control software which Preliminary realized the Online simulation.This paper has positive significance in evaluating traffic control strategy and the level of road service. The system of traffic induction and diverting can also be connected with the assessment of the online simulation to realize the issuance of the comprehensive traffic data
