The method comprises the following steps: building a plurality of data acquisition devices in a pilot area; collecting urban traffic data; establishing a model of an urban road network by using traffic simulation software; the signal timing scheme is input into simulation software; a final simulation result is obtained and applied to a traffic signal control system; feedback information after application is collected and sent to simulation software for improvement. According to the signal timing scheme optimization method based on traffic simulation, a large number of signal timing schemes are automatically generated according to the parameters, the workload of manual scheme configuration is greatly reduced, the final simulation result is closer to a real scene, the credibility of the simulation result is effectively improved, traffic flow data are acquired through the data acquisition equipment, and the traffic simulation efficiency is improved. Actual traffic flow data within a certain time can be efficiently counted, so that the data finally input into the model of the urban road network is more accurate and effective.
