Embodiment Construction
[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0037] Embodiments of the invention:
[0038] Such as Figure 1-Figure 3 As shown, a comprehensive multi-variable active traffic control method includes the following steps:
[0039] Step S1, division of lane control area and speed control area
[0040] The connecting section between intersections is divided into a speed control area and a lane control area, where the speed control area represents the area where vehicles can change lanes freely on the connecting road section, which can be used to implement speed control to reduce the discrete characteristics of the traffic flow and achieve the uniformity of the traffic flow; The lane control area refers to the area where vehicles need to pass according to the type of lane at the entrance of the intersection. It can be used t...

The invention relates to a comprehensive multivariable active traffic control method, which comprises the following steps: S1, dividing a connecting road section between intersections into a speed control area and a lane control area, S2, establishing an intersection active traffic control model, and S2, combining the active traffic control method, speed control and dynamic phase sequence control to obtain an intersection active traffic control model, and combining lane control and dynamic phase sequence control, wherein the logic that the lowermost layer is dynamic phase control, the middle layer is speed control and the uppermost layer is lane control is adopted, the speed control is adopted to suppress and rectify traffic flow firstly, then scheduling is conducted through lane control, and the method is more effective and reasonable. According to the invention, the dimension of the traffic control variable is extended, the full-distance control of the traffic flow is realized, and the traffic control capability is improved.
Description
technical field [0001] The invention relates to the technical field of traffic control, in particular to a comprehensive and multivariable active traffic control method. Background technique [0002] The urban road network is composed of intersections and road sections. The traffic flow in the road network generally originates from upstream intersections, forms in connecting road sections, and converges to downstream intersections. The traditional traffic control theory focuses on intersection control, and seldom considers the control of traffic flow on connecting roads. It is essentially a passive control method aimed at adapting to traffic flow. There are two main problems: 1) When the characteristics of the road network are not considered, the single intersection cannot realize the influence on the traffic flow through the way of upstream and downstream coordinated control, and it shows a passive adaptation method when adapting to the traffic flow, and it is difficult to ...
