The invention discloses a microscopic traffic semi-physical simulation tool, which comprises a signal machine communication module, an information processing module and a simulation software communication module, wherein the signal machine communication module is used for performing first communication with a traffic signal machine; the information processing module comprises a signal machine state thread which is used for sending signal state information acquired by the signal machine communication module to the simulation software communication module and a detector thread which is used forsending vehicle detector state information acquired by the simulation software communication module to the signal machine communication module, and the signal machine state thread and the detector thread operate synchronously; and the simulation software communication module is used for performing second communication with traffic flow simulation software. The beneficial effect is that the technical scheme can provide an excellent test and experiment platform for manufacturers of signal machines, traffic management departments and scientific search units.
Description
technical field [0001] The invention relates to the technical field of traffic simulation, in particular to a microscopic traffic semi-physical simulation tool. Background technique [0002] The traffic signal control system is an important part of the intelligent traffic management system. Its main function is to automatically coordinate and control the timing scheme of each intersection signal machine in the entire area, balance the traffic flow on the road network, and make the number of stops, delay time and Minimize environmental pollution and give full play to the benefits of the road system. The traffic signal control system is generally composed of three parts: the intersection information collection equipment, the upper computer of the control center, and the signal machine at the intersection: the intersection information collection equipment collects traffic data through coils, video, microwave radar and other equipment, and uploads this information to The upper ...
