Performance detector used for diverted traffic signal controller and detection method thereof

Abstract

The invention relates to a performance detector used for a diverted traffic signal controller and a detection method thereof. The performance detector comprises an industrial personal computer capable of operating traffic microcosmic simulation software and a controller evaluation system, an interface assembly and a traffic signal controller set, wherein the microcosmic simulation software can simulate the traffic of the diverted traffic, send simulation data to a traffic signal controller to be tested by the interface assembly; a control strategy is returned back to the interface assembly by the traffic signal controller so as to reset the phase of a signal lamp of the simulated diverted traffic, the interface assembly stores data of the simulation process in the controller evaluation system so as to evaluate the performance. The detection method is based on the performance detector. The traffic signal controller to be tested is connected with the interface assembly so as to form real-time hardware on a loop simulation platform with the microcosmic simulation software of the traffic, so that the simulation test and the performance evaluation can be carried out. The detection method provided by the invention can ensure the accuracy of the simulation results so as to make the performance detection results more comprehensive and objective. Moreover the detection method has the advantages of simplicity and rapidness, easiness in operation, and high repeatability.

Description

technical field [0001] The invention relates to a performance detection device and a detection method of a traffic signal controller at an intersection, which are used for traffic signal controller manufacturers to evaluate the control effect of the signal controller. Background technique [0002] The intersection traffic signal control system can allocate the right of way in time and space, so as to effectively guide the traffic flow at the intersection, and plays an important role in the traffic capacity and operation efficiency of urban road network traffic. Therefore, the quality of the control effect of the intersection signal control system is largely related to the state of urban traffic. Whether it can quickly and effectively evaluate the performance of the traffic signal control system has become an urgent problem to be solved. [0003] At present, there is no uniform standard for the performance detection of traffic controllers at intersections, and the methods fo...
