Traffic control method for road junction and traffic signal controller

Abstract

The present invention provides a traffic control method for road intersection. In the method, the road mark is used for identifying vehicle running directions; the left-hand turning mark is arranged on the left side of the road; the right-hand turning mark is arranged on the right side of the road; a direct traveling line is arranged in the middle; auxiliary traffic signals are used for controlling the beforehand turning of the vehicle. The present invention also provides a traffic signal controller which generates traffic signals and auxiliary traffic signals. The traffic control method and the traffic signal controller have the advantages of making full use of the idle resources of the road when the direct running is prohibited, turning in advance to prevent the intercross of turning and direct running, eliminating the signal period of time which singly allows turning, allowing simultaneous direct running and turning, and thus greatly improving the traffic efficiency of vehicles at the road intersection.

Description

technical field [0001] The invention relates to traffic control and operation, in particular to a traffic control method and a traffic signal controller at an urban road intersection. Background technique [0002] At present, with the growth of urban population and the increase of vehicles, while road resources are limited, urban traffic congestion is becoming more and more serious, and urban traffic problems have become a bottleneck restricting urban development. [0003] In order to solve urban traffic problems, governments, organizations and some individuals have come up with many ways and achieved great results. Such as: increasing road resources, constructing rail transit, urban elevated roads, full interchanges, etc.; increasing vehicle operating costs, limiting the total number of vehicles; vigorously developing public transportation and intelligent transportation; improving traffic management, etc., all have obvious effects. However, each city has its own situation....

AI Technical Summary

Problems solved by technology

However, each city has its own situation. Increasing road resources is the fundamental solution, but it requires huge investment. At the same time, whether the construction speed can catch up with the speed of demand is also a problem; increasing vehicle operating costs and limiting the total number of vehicles require It is the premise that it does not affect people's travel and the development of the city; it is the consensus of every city to vigorously develop public transportation, intelligent transportation, and improve traffic management, but its effect also depends on the history of urban road resources, bus operations and traffic management and level
