Research On Optimization Control Strategy Of Conjoint Crossings' Traffic

With the rapid development of China's economy, the development of road transportation is also on the rise. At the same time, the traditional off-line traffic control can not meet the actual demands nowadays. In recent decade,traffic abduction in the whole and partly automatic control are practiced to optimize traffic flow. At the same time , computer sciences and intelligence control begin to play a more important role in ITS. Just under this background, the optimization of local traffic control has got a further development.this thesis constructs a simple but usful on-line timing plan of conjoint crossings control, supplies process of period an phase optimizing base on green wave principle, uses two-levels fuzzy control and mathematics mould to decide green light delay.At the same time, I do simulication work on the above two strategies. Finally ,i anlaysed design course of traffic simulication software and GA. My experiment has proved that my strategies can produce good control result ,which is dependable.The inovations are as follow: new construct of whole control strategy,the application of fuzzy control , new mould, the forecast of Vehicle arrival Rate and the design of simulication SW.
