Abstract

The invention provides a trunk line cooperative control method for the intersection of two phase signals, and can solve problems that the green time is wasted and vehicles at the intersection are blocked because a conventional bidirectional green-wave control effect is poor. The method comprises the following steps: (1) designating a single cooperative control region according to an overall control strategy; (2) obtaining the phase differences between the two phase intersections in the cooperative control region and a trunk line upstream intersection and a trunk line downstream intersection, the minimum green-light time of cooperative phases of the two phase intersections, and the minimum green-light time t of non-cooperative phases; (3) determining a public period T of a cooperative control scheme; (4) determining a signal timing dial scheme of a conventional intersection, and determining a green-wave bandwidth t of green wave coordination; (5) judging whether green wave bands of the two phase intersections are set in the same signal period or not; (6) determining a signal timing dial scheme for two periods of the two phase intersections; (7) determining a cooperative control scheme of a signal cooperative control region.

Description

Technical field [0001] The invention relates to the field of urban road traffic control, in particular to the technical field of intelligent traffic signal system control, in particular to a coordinated control method for a two-phase signal intersection trunk line. Background technique [0002] In urban traffic, the main traffic line bears a large amount of traffic load, and the smooth traffic flow of the main line often has a great effect on improving the urban traffic conditions. The coordination and optimization of intersection signals will enable traffic flow to encounter a green light signal at the intersection without stopping and waiting, forming a "green wave belt" for two-way traffic flow on the road, which will greatly improve traffic congestion. [0003] At present, most signal-controlled branch intersections on urban arterial roads are controlled by two-phase signals. When formulating a signal coordinated control plan, half of the common period is generally used as the ...
