SURVEILLANCE SYSTEM FOR IDGHwAY MONITORING

Surveillance System for Highway Monitoring is an intelligent system which can detect
congestion in the highways and automatically alert the highway users. This project aims to
design and build a system which is able to monitor traffic congestion on highways and
automatically alert the users. This will help the road users in planning their journey by giving
them the current situation of the highways. The system consists of mainly the Programmable
Logic Controller (PLCs ), sensors and alert devices. This system functions to give awareness to
highway users and also help reduce highway congestion by monitoring the highways. The
infrared sensors will detect the vehicles and the PLC will be programmed to count the
frequency of vehicles that passes the sensor. If the frequency exceeds a certain limit, it will
firstly warn the highway users at the entrance of the highway and along the highway so that
they may use other road alternatives. If the frequency exceeds the second limit, then the
system will warn the highway users that the high is jam and recommends another route to be
taken.
