Embodiment

[0049] It is known that there are 5 intersections A, B, C, D, and E from south to north on a north-south main road, and the distance between adjacent intersections is 500 meters, 380 meters, 420 meters, and 140 meters. The belt speed is 10 m / s, and the calculation results of the signal timing design of each single intersection are shown in Table 1.

[0050] Table 1 Calculation results of signal timing design at each single intersection

[0051]

[0052] The two-way green wave coordinated control design of the arterial road under the independent release mode of the import is as follows:

[0053] The first step is to determine the allowable variation range of the common signal period

[0054] According to the change range of the signal cycle of each single intersection, the allowable change range of the public signal cycle is [90, 110] seconds.

[0055] The second step is to calculate the ideal intersection spacing under different public signal cycle values ​​and different ...

Abstract

The invention discloses an arterial road two-way green wave coordination control method in an entrance single release manner. The method comprises the following steps: determining an allowable variation range of a common signal period, computing an ideal intersection spacing with different common signal period values and in different signal phase sequence arrangement ways, determining an ideal phase sequence combination and an ideal common signal period of the arterial road intersection, and determining phase difference according to the direction of the intersections relative to the position of the ideal intersection, wherein, the step of computing an ideal intersection spacing with different common signal period values and in different signal phase sequence arrangement ways comprises respectively computing the ideal intersection spacing a by a time-distance graph based on the different phase sequence combinations of various intersections and the reference intersection; all of the distances d between the positions of various intersections and the position of the ideal intersection are 1/2v.C. The method can help enlarge a selection range for the value of the ideal intersection spacing, and is more applicable to the green wave coordination control of a plurality of arterial road intersections with different intersection spacings.

Description

technical field [0001] The invention relates to vehicle flow information control, in particular to a method for coordinated control of two-way green waves on arterial roads under the mode of independent clearance at entrances. 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 design method of the green wave belt on 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, that is, the green wave bandwidth obtained by the vehicle (vehicles at each coordinated intersection The length of the minimum green light time for continuous passag...
