Based On SCATS System Signal Control Scheme Design And Optimization

SCATS(Sydney Coordinated Adaptive Traffic System) is a widely used for traffic management system of the environment. According to the traffic flow in the light of the period adjustment phase, and the letter is sent, and phase to select the most suitable match.This paper to hefei the middle, for example, scats signal control system based on the design and optimize the process. Hefei city down the river is the main streets, known as "ROAD" in the first in Beijing, the chang'an boulevard, along through the provincial party committee, the government house, and large shopping malls and schools, restaurants, hotels and large number of residential, shops and travel to work, school and attracted a large quantity of. Besides, the section of junction, and the road conditions, therefore, the more prominent contradiction traffic. When to stop the driving conditions in the rear of the collision and change lanes the traffic accident. at that time, not carbon dioxide noticeable increase in the air pollution seriously.This subject in the design installation is completed, the gradual implementation of each intersection of the downgrade for the coordination of control (Flexilink) and all sections of the control pattern (Masterlink) to control the traffic lights. This thesis use an increase in the All-Red phase and Re-arrange phase, resolved the middle way to pedestrian crossing-PiHe the short questions, by crossing the road for the coordination and long period, solution of the Yangtze river runs down the road junction and-JinZhai the perimeter of the problem of heavy, Use of the two intersection adjustment phase and an increase in the early and down the river-HuiZhou avenue and the middle-SuZhou road junction heavy been thoroughly improve. Simultaneously, this thesis expound use SCATS put up VIP Route, deal with unexpected incident, and compatible with other intelligent traffic facilities such as to the traffic signal control and optimized.Road traffic signal control system to implement the control pattern (Masterlink) scheme, up the pace of (including the average speed and moving, speed) can greatly enhance the middle as the main streets in the use of the efficiency and improve the traffic capacity, reducing the time and time to reduce traffic delay, the social costs and economic costs. In addition, the rate of increase will be able to reduce vehicle emissions, to reduce air pollution and environmental quality is good.
