Controlling method and system for intelligent signal lights based on big data

Abstract

The invention discloses a controlling method and a system for intelligent signal lights based on big data. The signal lights is precisely controlled in real time according to current traffic flow at an intersection based on image recognition technology of YOLO algorithm and adaptive fuzzy control algorithm, so that traffic flow information collection and intelligent traffic lights control is realized; the big data sharing is performed in real time, and the current traffic lights and future traffic flow changes can be judged in time based on information sharing of the big data; and the trafficlights can be coordinated and controlled in real time by adjusting corresponding control strategy so as to effectively solve the traffic congestion problem caused by the traffic lights. Meanwhile based on real-time sharing of the big data realized by the controlling system for intelligent signal lights and through big data analysis, public transportation speed is configured to improve the abilityof public transportation, which is conducive to reducing fuel consumption and vehicle exhaust gas emissions, and achieving energy saving and emission reduction.

Description

technical field [0001] The present invention relates to the field of traffic control, in particular, to a method and system for controlling an intelligent signal light based on big data. Background technique [0002] In recent years, with the vigorous growth of my country's economy and the acceleration of the urbanization process, people's living standards have improved significantly, the number of motor vehicles has risen sharply, and the number of urban vehicles has continued to increase. The excess fuel consumption caused by traffic congestion has caused great energy waste and also caused great pollution to the environment. [0003] At present, there are two main control methods for urban traffic lights in my country: one is to use fixed-time timing control; the other is to use time-based control. [0004] Compared with the most traditional fixed-duration control, the time-based method is more advanced, and can alleviate the urban congestion problem to a certain extent. ...

Problems solved by technology

However, there are the following problems in its time-based control: 1. Inaccurate control; 2. It cannot cope with large fluctuations in traffic flow within a certain period of time.

However, due to the large body of the bus itself, its large mass and high inertia, frequent starting and stopping has not always given passengers a very good feeling, and compared with ordinary vehicles, its starting, braking and other operations waste more fuel and generate more energy.
