Automatic Traffic Control in Hilly Areas

This paper aims to reduce the number of road accidents occurring at hairpin bends in hilly regions and their serious impacts such as death and injuries by designing a Programmable Logic Controller system using sensors and a PLC. This system includes a programmable logic controller for communicating, monitoring, and controlling complex automated processes based on sensor inputs. The E18-D80 Proximity sensor detects when an object is nearby, initiating actions such as detecting the presence of a passing vehicle, and transmitting the signal to the controller. Controller is programmed using Ladder logic.
