Embodiment

[0055] The method of the present invention based on the traffic signal control machine dynamically matching the optimal signal timing scheme, the method is to formulate the signal light timing scheme through the traffic signal scheme experts, and set the corresponding rule judgment value in each signal light timing scheme, and the formulated The signal light timing scheme is stored in the traffic flow-signal scheme database; the real-time traffic flow of each lane is collected through road cameras or vehicle-mounted GPS, the traffic flow data is analyzed and judged by rules, and the dynamic programming algorithm is used to match in the traffic flow-signal scheme database To the optimal signal light timing scheme; the specific steps are as follows:

[0056] S1. Planning and construction of the vehicle flow-signal scheme database; wherein, the vehicle flow-signal scheme database includes a flow table (car_flow), a timing scheme table (signal_list), and a signal scheme issuing rec...

Abstract

The invention discloses a method for dynamically matching an optimal signal timing scheme based on a traffic signal controller, which belongs to the field of signal light control. The technical problem to be solved by the invention is how to collect traffic flow information on roads in real time and optimize the scheme timing. Predict the congestion index, propose a corresponding signal timing scheme for intersection traffic, and adjust the traffic flow. The technical scheme adopted is as follows: the specific steps of the method are as follows: S1. Planning and construction of the traffic flow-signal scheme database; S2. Predicting the congestion coefficient; S3. The traffic signal scheme experts formulate the signal light timing scheme and store it in the traffic flow-signal scheme database; S4, make regular judgments on the real-time traffic flow in any time interval, and match the optimal signal light timing scheme for the next time interval; S5. Pack the obtained signal light timing scheme into a scheme that can be recognized by the signal machine platform and send it to the signal machine platform, so as to realize the real-time dynamic adjustment of the traffic signal light at the traffic intersection.

Description

technical field [0001] The invention relates to the field of signal lamp control, in particular to a method for dynamically matching an optimal signal timing scheme based on a traffic signal controller. Background technique [0002] Domestic intersections mostly use traffic signal control machines to control and manage traffic signals. According to statistics, as of 2018, there are about 130,000 traffic signal control intersections in my country. Traffic signal controllers are all set timing control schemes, including single-stage timing control and multi-stage timing control. The timing scheme used in the timing control method is formulated according to the historical data of the traffic survey, and will remain unchanged until the next traffic survey. [0003] The traffic police are the direct managers of road traffic control. The traffic police need to set different timing schemes in the signal control machine in advance according to the traffic flow and pedestrian densit...
