Problems solved by technology

The above research has good practical value at intersections where right-turning traffic flow conflicts with straight-going pedestrians and non-motor vehicles, but it is not effective at intersections where straight-going and right-turning traffic flow converge and conflicts are serious, because there has been a lack of information on straight-going and right-turning traffic.

Abstract

The invention discloses a right-turn signal induction control method for eliminating a straight-right-turn convergence conflict. According to the invention, on the basis of statistics of conflict data of straight road traffic flows and right-turn traffic flows at lots of intersections, a conflict rule of a straight road vehicle and a right-turn vehicle is obtained based on analyses; a theoretical computation model of the traffic capacity of the through-right-turn convergence lane is established; a starting threshold value for right-turn signal controlling is determined by setting the maximum convergence lane traffic capacity as a goal; and a scheme of right-turn signal control at an intersection is formulated according to a relation between a through traffic flow detected in real-time and the threshold value. Therefore, the mutual influence on the through flow and the right-turn flow is minimized; and the lane resource utilization rate is highest.

Description

technical field [0001] The invention relates to the field of traffic signal control, in particular to a right-turn signal induction control method for the conflict of straight-right confluence at an intersection. Background technique [0002] Setting the right-turn signal control method refers to the signal control method adopted for the problem of reducing the traffic efficiency of the merging lane in the case of the convergence conflict between the straight vehicle and the right-turn vehicle, and the purpose is to separate the direct-right convergence conflict. The phenomenon of straight-right convergence conflict at a road intersection is defined as the obvious deceleration behavior of the straight-going car due to the competition for the right to use the road between the right-turning car and the straight-going car. The capacity of the straight-right inbound lane refers to the maximum number of vehicles passing through the collision point location in one hour under the c...
