Intelligent traffic signal control method based on open-source road condition information

Abstract

The invention discloses an intelligent traffic signal control method based on open-source road condition information, and solves the problem that the intelligent degree of traffic signal control stillneeds to be improved in the prior art. The method comprises the following steps: step 1, collecting traffic data under an open-source real-time road condition; 2, evaluating a congestion index; 3, constructing an intelligent signal period model; and step 4, constructing an intersection signal lamp timing model based on the open-source real-time road condition traffic data. The technology is mainly used for coping with traffic congestion in peak hours; experimental results are consistent with expectations; the heavier the traffic is, the better the relieving effect of the method is; the congestion queuing is reduced by 16.14% under a general congestion condition, while the congestion queuing is reduced by 29.99% under a severe congestion condition, so that the traffic capacity of the roadis obviously improved; and on one hand, the urban road construction cost can be saved, and on the other hand, the vehicle travel cost can be reduced.

Description

technical field [0001] The invention relates to the field of intelligent traffic, in particular to an intelligent traffic signal control method based on open-source road condition information. Background technique [0002] With the development of social economy and the acceleration of urbanization, the population and vehicles in cities have increased dramatically, and the problem of traffic congestion has become more and more serious. In megacities, traffic congestion has seriously affected people's work and life. In Beijing, China, the urban area is 1445.54km2, the urban population is 21.542 million, and the average speed of vehicles during peak hours is only 23.35km / h. In the early days, megacities mainly solved the problem of traffic congestion by building new roads, building overpasses and building subways. However, there are two problems in this method. One is that urban land resources and space are limited, and it is impossible to build unlimited roads. A large amount...
