Problems solved by technology

[0005] In the existing technology, the traffic signal control lacks the support of real-time traffic data, and most of the signal timing is still designed based on historical experience, which cannot reflect the actual situation of the road in time, resulting in unreasonable intersection signal timing and serious loss of green lights in some directions. , and cannot adapt to the dynamic change process of traffic flow

Embodiment 1

[0040] Embodiment 1, with reference tofigure 1 , a balanced and coordinated control system for real-time perception of pedestrians and motor vehicles,

[0041] The system is composed of a central traffic signal control system, several crossing field devices and a transmission network. The single crossing field devices include crossing signal controllers, video vehicle detectors, traffic lights, pedestrian crossing request buttons and pedestrian crossing voice prompt columns;

[0042] The central traffic signal control system and several intersection signal control machines are connected based on the broadband bus connection based on the Internet protocol address. The central traffic signal control system synchronizes the operating parameters of the intersection signal control machines and the real-time request data of pedestrians and motor vehicles for calculation, analysis and communication. Comprehensive processing, while sending relevant control instructions to the intersect...

Embodiment 2

[0045] Embodiment 2, a road coordination control method based on pedestrian and motor vehicle information, the method uses the balanced coordination control system of real-time perception of pedestrians and motor vehicles described in Embodiment 1, and the method steps include:

[0046] (1) According to the road network structure, multiple intersections are divided into a control sub-area according to their relevance, and the traffic information in the control sub-area is investigated and analyzed;

[0047] (2) According to the surveyed traffic data, analyze it, and use the network green wave coordination control method to design a signal timing scheme;

[0048] (3) Send the signal timing plan to the signal control machines at each intersection and run it, observe and analyze the operation situation, and fine-tune and optimize the green wave bandwidth, green signal ratio, and phase difference;

[0049] (4) The real-time detected motor vehicle signal and pedestrian crossing req...

Embodiment 3

[0062] Embodiment 3, pedestrian and motor vehicle information to realize road coordination control system and control method experiment:

[0063] The section from Zhongshan Road, Pingshan Road, Lianyun District, Lianyungang City to Haibin Avenue was selected as the test section. The total length of the research section is 3140 meters, and there are 12 intersections with an average distance of 285 meters, including 6 pedestrian crossings.

[0064] Refer to attached figure 1 , the system is mainly composed of a central traffic signal control system, several intersection field devices and a transmission network. The field devices at a single intersection include intersection signal controllers, video vehicle detectors, traffic lights, pedestrian crossing request buttons, and pedestrian crossing voice prompt columns.

Abstract

The invention relates to a balanced and coordinated control system for real-time perception of pedestrians and motor vehicles, which belongs to the field of road traffic signal control of intelligenttransportation. The system comprises a center traffic signal control system, a plurality of pieces of intersection field equipment and a transmission network. The field equipment at a single intersection includes a traffic signal controller, a traffic signal lamp, a vehicle detector, a pedestrian crossing request button and a pedestrian crossing voice prompt column. The invention further providesa balanced and coordinated control method for real-time perception of pedestrians and motor vehicles. The system and the method of the invention well combine green wave coordinated control, delay coordinated control and pedestrian crossing request control, realize balanced and coordinated control of motor vehicles and pedestrians, and can obviously improve the travel experience of traffic participants.

Description

technical field [0001] The invention relates to the field of road traffic signal control of intelligent transportation, in particular to a balanced and coordinated control system for traffic signals of pedestrians and motor vehicles at multiple intersections in an urban road network, and the invention also relates to a balanced and coordinated control system for real-time perception of pedestrians and motor vehicles method. Background technique [0002] In recent years, with the continuous growth of my country's economy, the number of motor vehicles has continued to increase, and the number of urban populations has also continued to increase. The pressure on urban traffic operations has become greater and greater. Traffic congestion and accidents on the roads have occurred frequently in major cities. life has brought many inconveniences. [0003] With the continuous advancement of smart city construction, the demand for intelligent transportation construction continues to ex...
