Embodiment Construction

[0063] The present invention is described below as a preferred solution of the above-mentioned solution in conjunction with specific examples, but the present invention is not limited to these specific implementations. Those skilled in the art will realize that the present invention covers all alternatives, modifications and equivalents as may be included within the scope of the claims.

[0064] see figure 2 , the present embodiment provides a city-level signal recommendation system based on spatio-temporal similarity, the recommendation system is composed of five main parts: database module, real-time traffic analysis module, information control recommendation module, signal control system module and evaluation module . The system operation process is as follows: First, the real-time traffic analysis module recognizes the deterioration of traffic conditions at a certain intersection in real time, and triggers the signal control recommendation module. Then, the signal contr...

Abstract

A city-level signal recommendation system based on spatio-temporal similarity, including a real-time traffic analysis module, which is used to detect the traffic operation status of each intersection in the urban road network in real time, and judge whether it exceeds the carrying range of the intersection, so as to determine the intersection that needs to be intervened in time and Trigger signal control recommendation module; signal control recommendation module, used to recommend real-time signal control schemes based on time-space similarity and send them to the signal control system module; database module, used to save system data; signal control system module, used to execute the delivery The real-time signal control scheme; the evaluation module is used to evaluate the effectiveness of the signal control scheme.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and relates to a city-level signal recommendation system based on time-space similarity. Background technique [0002] Urban traffic signal control is one of the most effective ways to solve urban traffic problems. Signal control strategies can be divided into timing strategies and adaptive strategies. Timing strategy includes single-point adaptive strategy and adaptive coordination strategy. The single-point adaptive coordination strategy is suitable for a single intersection, while the adaptive coordination strategy considers an urban area or even the entire urban road network. Timing policies are based on historical rather than real-time demand. Therefore, the timing strategy obviously cannot adapt to the changing traffic conditions. For example, accidents or other unpredictable events can disrupt traffic conditions. In the past few decades, some adaptive signal control systems h...
