A signal coordination control method between road intersections under variable period

Abstract

The present invention provides a signal coordination control method between road intersections under variable cycle, which can solve the cycle and scheme of traffic signal control that cannot be well controlled according to traffic flow changes in the existing arterial intersection signal coordination control method Real-time and flexible optimization and adjustment of the phase difference can effectively improve the utilization rate and traffic capacity of green lights at intersections, reduce the number of parking times, ensure the effect of coordinated control of green waves on main lines, and realize the rapid conversion of signal coordination control schemes, eliminating The traffic impact generated during the conversion of signal coordination control scheme is analyzed. It monitors the traffic flow data of each intersection in real time, calculates the best coordinated control public period value in real time, optimizes and adjusts the urban arterial traffic signal coordinated control scheme, selects the optimal phase difference, and realizes the rapid adaptation of the arterial traffic signal coordinated control scheme Changes in road traffic flow, thereby improving the effect of coordinated control of arterial traffic signals.

Description

Technical field [0001] The invention relates to the technical field of intelligent traffic signal system control, in particular to a signal coordination control method between road intersections under variable cycles. 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 make the traffic flow meet the green light signal at the intersection without stopping and waiting, forming a "green wave belt" for two-way traffic flow on the road, thereby greatly improving traffic congestion. [0003] At present, the signal coordination control schemes between intersections on urban arterial roads all adopt a fixed signal cycle. The signal control cycle and scheme of each intersection cannot be adjusted in real time according to changes in traffic flow, resulting in the gree...
