The Design And Realization Of Intelligent Traffic Signal Control System

Intelligence Traffic Signal Control System offers a potentially effective settlement for city traffic management.In the past decade,it has been a popular issue in Intelligence Traffic Signal Control System with increasing concern for its large-scale application and potential business benefits.Current there are a variety of commercial Intelligence Traffic Signal Control Systems, there is an urgent need to address the issues of standardization and intelligence in the development of ITC.In the thesis,we focus on two core issues of standardization and intelligence, research on some aspects of open architecture based ITC,our work contributes to the following aspects:1. Open Architecture based ITC research. In reference to some foreign open system standards about ITC, puts forward the open architecture based ITC standards suited to China's national conditions. It supports the NTCIP standard. Multiple-phases mode is the control mode commonly used in China. Ring-Barrier mode is used in NTCIP. The difference and the conversion between Multiple-phases mode and Ring-Barrier Mode are discussed.2. Design an open architecture based ITC. The system is designed with the idea of Open architecture, supporting the NTCIP standard and providing detection and control API of traffic signal light, the system can be easily expanded and integrated. Car flow detectors are integrated with Intelligent Traffic Signal Controller to form a closed loop control system, running the self-adaptive control algorithm, increasing intelligence to the system, achieving good control results.3. Design the background on ITC. Create corresponding data-base, use ITS platform, the information can be achieved by ITC and then be saved in database and illegal system by interface. It can increase the application of systems, and integrate all the modules.
