Embodiment

[0062] It is known that there are four intersections A, B, C, and D from south to north on a north-south main road. The distance between adjacent intersections is 485 meters, 650 meters, and 150 meters. 10 m / s. Assuming that the east and west entrances of each intersection adopt separate entrance clearance mode, the signal phase setting method of the north and south entrances is not restricted, and the green light interval is simplified to 0 seconds. The relevant signal timing design requirements are shown in Table 1.

Abstract

The invention discloses a universal phase position type artery two-way green wave coordination control method. The method includes the steps of determining allowed signal phase position setting modes of the artery directions of various intersections, formulating a split allocation scheme of all the intersections in the different allowed signal phase position setting modes, determining value ranges of commons signal periods of arteries, calculating values of the different common signal periods and ideal intersection intervals in the different signal phase position setting modes, determining the best signal phase position setting mode of all the intersections of the arteries and the best common signal period of the arteries, calculating phase differences of all the intersections of the arteries and obtaining widths of two-way passing zones. The method cannot be limited by the signal phase position setting modes of the intersections of the arteries, can be applied to the optimization design of an artery two-way green wave coordination control scheme in various phase position setting modes and has good universality and a wide application range.

Description

technical field [0001] The invention relates to the field of coordinated control of traffic signals, in particular to a two-way green wave coordinated control method for a common phase arterial road. Background technique [0002] The green wave coordinated control of arterial road is to connect multiple intersections on the arterial road in a certain way as the research object, and at the same time carry out a coordinated timing scheme design for each intersection, so that as many arterial road vehicles as possible can obtain non-stop right of way. The green wave belt design method of the arterial road will determine the signal timing parameters of the arterial coordinated control system by seeking to maximize the ratio of the green wave transit time to the public signal cycle, and use the green wave bandwidth as an evaluation index to study the coordination of the arterial timing scheme. Control effect. [0003] At present, the commonly used two-way green wave coordinated...
