Embodiment Construction

[0016] Using RFID electronic tags as the information intermediary, build a two-way communication between the vehicle and the intersection control layer. By using the RFID reader installed at the intersection, read the number of vehicles equipped with electronic license plates in the section of the road section, and use the vehicle density in the section of the road section as the control index Conduct induction control on the induction phase, so that the induction coordination control induction phase can overcome the failure of the induction control when the traffic flow is oversaturated; the coordination phase of the induction arterial road coordination control operates in the mode of a fixed timing scheme, participates in intersection coordination, and non-coordination phase Operate in accordance with the induction control mode to adapt to the randomness of the arrival of traffic control traffic, to achieve the purpose of green wave control on the main road and effective use o...

Abstract

The invention relates to an inductive arterial road coordination control method based on an electronic tag. An induction phase reads the number of vehicles with electronic license plates in a road section through an RFID reader which is arranged at an intersection. The density of the vehicles in the road section is used as a control index to carry out induction control on the induction phase, so that the inductive coordination control induction phase overcomes failed induction control when traffic flow is supersaturated. The inductive arterial road coordination control coordination phase operates in a fixed timing scheme mode, participates in intersection coordination. A non-coordinated phase operates in an induction control mode to adapt to the randomness of traffic flow reaching under traffic control. Main road green wave control is realized. The green light time of secondary road traffic flow is effectively used. The average delay and the average number of stops of vehicles at the intersection can be effectively reduced.

Description

technical field [0001] The invention relates to a traffic signal control technology, in particular to an inductive arterial coordinated control method based on an electronic tag. Background technique [0002] At present, most of the intersections in our country still adopt fixed coordinated control, mainly by allocating more green light time to the main road to realize the green wave control of the main road, so as to realize the continuous traffic flow of the main road through multiple intersections without stopping. However, the arrival of the traffic flow is random, and the fixed coordination control will increase the delay at the intersection. [0003] Inductive control coordinated control can adjust the green signal ratio according to real-time traffic flow data. It is more adaptable to the random arrival of vehicles, which can make vehicles stop as little as possible before the stop line, improve the utilization rate of green lights, and achieve smooth traffic.
