Problems solved by technology

However, most of the traditional signal light control adopts the method of fixed signal cycle, fixed duration and fixed phase conversion sequence, which cannot control the intersection signal in real time and economically, so that the phenomenon of "green light, no car, red light blocking" occurs from time to time, sooner or later Peak hours and holidays are more obvious

Embodiment

[0057] image 3 It is a schematic diagram of a single intersection system scenario, and four phases are set to avoid traffic conflicts. It is mainly composed of traffic data acquisition device, intelligent traffic lights and traffic server.

[0058] The data acquisition device includes intersection cameras and other devices, which are used to count the traffic flow at the exit of each lane and the flow of pedestrians and non-motor vehicles on the non-motorized lane, and upload them to the traffic server.

[0059] Intelligent traffic lights: implement the timing plan fed back in the manual system, and independently set the corresponding phase sequence and traffic light duration.

[0060] Traffic server: Use the collected data to build an artificial traffic light timing system and dynamically decide on a timing scheme.

[0061] specific plan:

[0062] 1. Phase sequence decision:

[0063] Use the data acquisition device to collect the vehicle queuing length of each phase and ...

Abstract

The invention discloses an ACP-based real-time control method for parallel traffic signal lights. The method comprises the following steps: step 1: building a traffic flow data collection system and a database for a single intersection; step 2: building an artificial signal light system; step 3: importing real-time traffic flow data collected by the data collection system into a computing experiment platform, Calculate the real-time timing scheme; Step 4: Load the calculation and experiment results into the actual traffic signal system in parallel execution to realize the induced intervention on real-time traffic flow; Step 5: Build an intersection status evaluation system. The traffic light timing in this paper has the following characteristics: First, the time-varying universe theory is used to calculate the experimental process, and the membership function of the fuzzy set is adjusted in real time according to the periodic change; secondly, the timing scheme in this paper is real-time, and the timing period and each The duration of the phase is adapted to the condition of the traffic flow; thirdly, through the calculation experiment of the artificial system, the decision-making efficiency of the system is improved.

Description

technical field [0001] The invention relates to the field of intelligent traffic, in particular to an ACP-based real-time control method for parallel traffic lights. Background technique [0002] With the rapid development of social economy, urban vehicles continue to increase, and the traffic system is becoming more and more complex. The randomness and unpredictability of the behavior of pedestrians and motor vehicles make it difficult for people to establish accurate mathematical models. Good results. For intersections where vehicles and pedestrians are concentrated, the problem is particularly obvious, which is a high-occurrence area of ​​congestion in the entire urban road traffic. Various traffic flows (motor vehicles, non-motor vehicles and pedestrians) repeatedly merge, diverge and cross at level intersections, making the traffic conditions extremely complex, so urban traffic congestion is often manifested at intersections, improving its traffic efficiency is the ke...
