TRAFFIC LIGHTCONTROL SYSTEM BASED ON DENSITY AND USING RASPBERRY PI

Abstract

Nowadays, there is an increase in vehicle traffic everywhere, particularly in cities. In the future, smart traffic management will become a critical problem as the number of road users continues to rise. Traffic congestion is starting to become a major problem. Due to the lengthy wait times at traffic signals, more time is spent by humans, which causes several issues for those who commute to work and for those who work for businesses. The current system does not regulate traffic in accordance with density and does not lessen the impact of traffic in urban areas. Traffic lights are created in advance and fixed for a certain amount of time before being changed to a different signal. The other side roads are delayed significantly as a result. There were instances when traffic signals malfunctioned. The suggested system measures the number of vehicles and reduces traffic correspondingly by using image processing and a Raspberry Pi. With the use of an RF transmitter and receiver, emergency vehicles such as ambulances and fire engines may be readily admitted into traffic. Vehicles that resemble ambulances transmit a signal to a receiver, which causes the green light on the road to shine. This improves the safety of the patients within the ambulance, and it also applies to fire trucks. When the red light is on, road crossings are avoided thanks to infrared sensors. A density-based traffic control system helps to monitor traffic updates. The Raspberry Pi and modules including a camera, infrared sensor, radio transmitter, receiver, and actuator are the hardware components utilised in the project. These modules are interfaced with the Raspberry Pi in order to regulate traffic and ensure correct output. The background removal approach in image processing is used to create software. Python is the programming language utilised to carry out the implementation. The VNC viewer programme is used to carry out the implementation using these hardware and software components. The module will operate in accordance with the programme, which has already been thrown into the application.
