Traffic Signal Control System using Microcontrollers

Project Domain / Category

Automation / Embedded System Programming 

Abstract / Introduction

In the present days automated systems or embedded systems have fewer manual actions. They are much more flexible, reliable and much accurate as compared to our manual systems. Due to increase in demand of such reliable and flexible systems, we prefer an automated control system.

In Pakistan, controlling traffic system is one the basic challenge. The monitoring and control of city traffic signals are becoming a major problem in many cities and with the increase in the number of vehicles on the road, the Traffic Control and Monitoring Authority has to find new automated methods of overcoming traffic related problems.

The main aim of this project is to design an intelligent traffic light controller using embedded system. Which will also aim to design a safe and efficient traffic flow and to assign the right way and minimizes the delay or waiting time at the road.

Functional Requirements:

 Control signal light delays

 Control signal pass through mechanism

 Remotely camera observation mechanism

 Emergency Diversion

 Remotely linked with other signals using wireless interface.


 Microcontrollers (Intel 8051/8052 series)

 C/C++ Programming Language

 Assembly Language

 Circuit Designing Software’s (Or CAD Pspice, Workbench)

 Keil Embedded Development Kit

 Microcontroller Burner Kit

 Circuit Components (Resistors, Capacitors, oscillators etc.)

 Wireless interface devices (ZigBee etc.)
