Test verification system for active control of urban traffic

Abstract

The invention discloses a test verification system for active control of urban traffic, which belongs to the technical field of urban road traffic and the system comprises an online traffic control simulation system, an in-loop semi-physical sand table simulation system and an on-site traffic control system which are formed by signal connection of a virtual traffic signal controller and an entity traffic signal controller. In the simulation process, a control strategy can be verified without limitation, the control strategy is firstly sent to the semi-physical sand table simulation system, and when the control strategy is verified to be available and safe, the control strategy is input to the actual traffic signal controller on site, so that an online-in-loop-on-site execution inspection mode is formed. The system can effectively solve the serious problems that the effect of a traffic control strategy is obvious in theoretical research, and model mismatch, control strategy failure and the like often occur in practical application.

Description

technical field [0001] The invention relates to the technical field of urban road traffic, in particular to a test verification system for active control of urban traffic. Background technique [0002] With the continuous increase of car ownership, urban road congestion is becoming more and more serious. Traffic control is the main means to alleviate traffic congestion and solve traffic problems. However, in the current traffic control field, there are obvious effects in theoretical research, but in practical applications, there are often extremely serious problems such as model mismatch and control strategy failure. This is because there are two typical problems in the verification test of the current traffic control strategy: 1) When constructing the control model, strategy or optimization method, the assumptions are too ideal, the constraints are too broad, and the various conditions that may exist in the actual scene are not considered. Problem; 2) Simulation is a brid...

Problems solved by technology

[0003] The present invention provides a test and verification system for urban traffic active control, from the "online" simulation system to the "in-the-loop" semi-physical sand table simulation and then to the "on-site" practical application of the traffic signal control machine, to bridge the gap between simulation and reality, Realize the high-efficiency reachability from model->control strategy->control machine, which can effectively solve the problem that the theoretical simulation effect of the current control strategy is obvious and cannot be practically applied in the field
