[0005] The basic content of the present invention is: aiming at the problem of real-time control of urban traffic signals with complex characteristics, a new self-organized construction method of urban traffic signal intelligent control rules based on urban road network parameters and fluid dynamics is proposed. On the basis of cellular automata, fluid dynamics are introduced to establish a balance model of traffic flow. By endowing each independent intersection with independent decision-making ability, and taking the interaction between adjacent intersections as the evolutionary driving force, a local traffic flow is formed from bottom to top. The self-organizing control rules of the intersection and the global road network, and the real-time decision-making of the traffic system signal mode can be realized by formulating the phase discrimination rules of the traffic intersection, which can effectively reduce the calculation amount of the system and solve the problem caused by the excessive calculation amount of the current control strategy. Unable to meet the real-time problem of unified control of the global road network and achieve the purpose of intelligent traffic control

Embodiment Construction
[0075] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.
[0076] figure 1 Indicates the 12 phases corresponding to the intersection, and the entire signal cycle is according to f(2) or f(8), f(1) or f(7), f(3) or f(9), f(5) or f( 11), f(4) or f(10), f(6) or f(12) for phase switching, if the right turn is allowed to pass through, then cancel the right turn phase switching order; if the phase in the latter sequence is included in the front If there are two or more lanes with the same passing phase at the same time, their parameters will be included in the phase decision equation. If a lane has two or more passing phases at the same time, Then its parameters all participate in the decision equation of each phase included.

A self-organized construction method of urban traffic signal intelligent control rules, which localizes all intersections in the traffic road network according to the interaction, and transforms the interaction between complex traffic flows into The real-time rule expression inside the system can control the traffic flow on demand or automatically to achieve the purpose of intelligent traffic control. The characteristics of the present invention include: fully considering the impact of road form on traffic flow, thereby ensuring the universality and stability of the method; intelligently allocating passing time, reducing parking waiting, and improving passing efficiency; intelligent signal switching mode, which can Different switching methods are adopted according to different traffic conditions, which more effectively improves the road traffic capacity; effectively and greatly reduces the calculation amount of the system, and solves the problem that the current control strategy cannot meet the unified control of the global road network due to the excessive calculation amount real-time issues.
Description
technical field [0001] The invention belongs to the technical field of traffic intelligent control, and relates to a self-organized construction method of urban traffic signal intelligent control rules. technical background [0002] The urban traffic system is a typical, open and complex system composed of road system, flow system and management system. Any method that relies on the traditional "top-down" large-scale system centralized control is difficult to solve this kind of strong real-time , The problem of controlling the characteristics of heterogeneous big data. At present, there are many kinds of intelligent traffic signal control systems at home and abroad, the core of which is to adopt the strategy of passive control. The method actually avoids the complexity of the system; It has a certain applicability in large cases; as the system environment becomes more and more complex and the frequency of traffic flow changes intensifies, its control performance will declin...
