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 an adaptive signal control method and system in an intelligent networked environment. The method comprises the following steps: acquiring trajectory data of a vehicle; acquiring traffic signal light information; When the vehicle arrives at the intersection, add the updated real-time queuing information after queuing; build a dynamic programming model; obtain the corresponding optimal phase green light duration according to the obtained dynamic programming model; control the traffic lights according to the obtained optimal phase green light duration of the corresponding state stage. Traffic signal indication. The self-adaptive signal control method in the intelligent networked environment provided by the present invention provides the self-adaptive signal control method that supports real-time response to changes in traffic demand, and at the same time meets the requirements of normalized traffic control. Optimize the allocation of the green light phase duration, make full use of time and space resources, and maximize the overall operational efficiency of the intersection.

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 networked environment. Background technique [0002] In the urban road environment, the travel demand is greatly affected by the depth of time and fluctuates greatly. 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 the intersection during the travel peak period, resulting in waste of time and space resources and traffic. Efficiency drops severely. With the accelerated construction and implementation of intelligent networked infrastructure in the urban open road environment, the development of intelligent networked-based intelligent traffic signal control systems to meet time-varying traffic travel needs has become an important means to solve the problems of traffic congestion and waste of...
