Problems solved by technology

[0004] The invention provides a two-way linkage control method for adjacent intersections considering the dynamic queuing length. On the basis of considering the dynamic queuing length of the linkage control vehicle flow, the two-way linkage of adjacent intersections is realized by optimizing the timing parameters of the linkage control intersection signals. Signal control, to overcome the shortcomings of the previous urban traffic signal linkage control algorithm complex, unoptimized public cycle and poor practical application effect

Embodiment 1

[0022] Embodiment 1: as Figure 1-2 Shown, a kind of adjacent intersection two-way linkage control method that considers dynamic queuing length, the specific steps of described method are as follows:

[0023] A. First determine the linkage control of adjacent intersections and the linkage control of traffic flow;

[0024] Linkage control intersections are directly connected in physical structure, and there are no entrances and exits that affect the normal operation of motor vehicle flow. In order to prevent linkage control traffic flow from being too discrete, the distance between linkage control intersections should not exceed 1,000 meters, and linkage control intersections should be in an unsaturated state. ;

[0025] Select the traffic flow with large flow and high correlation between linkage control intersections as the linkage control traffic flow. Considering that two-way linkage control is required, the linkage control traffic flow at the same intersection is in the sa...

[0036] The specific steps of the two-way linkage control method at adjacent intersections considering the dynamic queuing length are as follows:

[0037] A. figure 2 Intersection 1 and Intersection 2 serve as linkage control adjacent intersections, and the distance between intersection 1 and intersection 2 is 400 meters, among which traffic flows 11, 14, 21, and 24 are linkage control traffic flows, and linkage control traffic flow is between intersection 1 and intersection 2. The travel speed between intersection 2 is 10 m / s, traffic flow 13, 16, 23, and 26 are non-linkage control traffic flow, and right-turn traffic flow has no signal control;

[0038] B. The signal control parameters of the investigatio...

Description

technical field [0001] The invention relates to a two-way linkage control method for adjacent intersections considering the dynamic queuing length, and belongs to the technical field of traffic control. Background technique [0002] With the rapid development of my country's economy, the number of motor vehicles has increased rapidly, especially the number of private cars has increased day by day, which has led to the rapid growth of urban road network traffic demand. In order to alleviate the problem of traffic congestion, the country invests a huge amount of money in road network construction every year, but compared with the rapidly increasing traffic demand, the traffic supply capacity that the newly built road network can provide is far from enough. Moreover, relying on road network construction to meet traffic demand has unavoidable disadvantages, such as the long period of time required for road construction, the huge amount of money required, and the impact on the no...
