Problems solved by technology

However, on the one hand, these methods are likely to cause a decline in the overall traffic operation efficiency of the intersection, resulting in the loss of other social vehicle operation efficiency, which cannot effectively solve the congestion problem at the intersection; serious losses, during peak travel periods, aggravating intersection congestion

Abstract

The invention discloses a self-adaptive signal control method and system in an intelligent network connection environment. The method comprises the following steps: acquiring trajectory data of a vehicle; acquiring traffic signal lamp information; according to the track data and the traffic signal lamp information, on the basis of a traffic wave model, obtaining real-time queuing information updated after the vehicle is queued when arriving at the intersection; constructing a dynamic planning model; according to the obtained dynamic planning model, obtaining a corresponding optimal phase green light duration; and controlling a traffic signal lamp to carry out traffic signal indication according to the obtained optimal phase green light duration of the corresponding state stage. According to the self-adaptive signal control method in the intelligent network connection environment, the self-adaptive signal control method supporting real-time response to traffic demand changes is provided, meanwhile, the normalized traffic control requirement is met, on the basis of a signal timing mechanism, the green light phase duration is optimally distributed in a staged mode, space-time resources are fully utilized, and the traffic control efficiency is improved. And the overall operation efficiency of the intersection is maximized.

Description

technical field [0001] The invention relates to the technical field of traffic intelligent control, in particular to an adaptive signal control method and system in an intelligent network environment. Background technique [0002] Under the urban road environment, traffic travel demand fluctuates greatly due to the influence of time depth. Because the existing urban traffic control system does not have the ability to respond to travel demand in real time, it is easy to cause traffic congestion at intersections during peak travel periods, resulting in waste of time and space resources. Efficiency is severely reduced. With the acceleration of the construction of intelligent network infrastructure in the urban open road environment, the development of intelligent traffic signal control systems based on intelligent network to meet the time-varying traffic travel needs has become an important means to solve the problems of traffic congestion and waste of time and space. [0003]...
