Image Processing Based intelligent traffic light system

MAKERS: Vibhutha Kumarage

The purpose of this project is to design an image processing based intelligent traffic light control system. The main input of the system is the video feed of the traffic by CCTV cameras.4 CCTV cameras are implanted at the center of the 4 way junction. The best viewing angel of cameras is found by the proper study on project drawings. These cameras 24/7 online and feed the video to the system. The system consist 4 major parts. 1. Image processing based computer program. 2. Controller program. 3. Electronic controlling system. The image processing based computer program collect the video feed from CCTV cameras. The computer program is programmed to remove the background of the video and extract only vehicles from the video and count them. This program is programmed using OPEN CV [Computer Vision library] and C++ next, the vehicle count which is calculated by the program feed into Controller program. It is programmed by using C++. Main task of the program is analyzing the vehicle count of each lane of the 4 way junction and give them a priority level. The priority loop of the junction is mentioned in project image.The priority level of the path is expressed in numbers. And t(x) [x=1,2,3,4] is time period between 2 priorities. Priority level of each path and t(x) are calculated using a mathematical formulas considering traffic density of each path, what is the main path, what is the time and the day etc. facts. All calculated time values [t(x)] which are calculated by the software feed into the electronic control system. Electronic system micro-controller controls the all electronic parts including CCTV cameras and traffic light LED s.
