Traffic Control System

How often do you reach your workplace late despite a punctual set out from home? Hail the poor traffic management of your city or may be due to a minute’s delay on the part of traffic police. A good traffic management system is the need of the hour. Here is a traffic control system project from young engineers featured at Multyremotes.com in which a police man can control the flow of traffic from a remote location through his computer.

The system is programmed such that the flow of traffic can be diverted to any lane by switching the traffic lights remotely at just a click of the mouse. This system is designed to control four different lanes simultaneously. The current traffic scenario can be monitored on the screen of your computer. Hence, there are two sections of the project:

1) Hardware

2) Software

The software or the source code is an inevitable part of the project which acts as a brain behind making the whole system automatic. Whether working in manual or automatic mode, all signals are interpreted and processed for the machine to understand and system to react through the software control. The program is written in VC++.

The hardware consists of traffic light control system. The main components are 2 input quad OR Gate IC 74LS32, NOT gate IC 74LS04, current driver IC ULN2003A and timer IC 555. Depending on the input binary data given at the port, traffic lights are controlled as in switching the red lights off and turning on the green ones at a particular lane. However in the automatic control mode, traffic lights are switched on/off automatically as per the pre-programmed time interval. At a time only one of the red, green or yellow led will glow. A total of 12 Leds for each lane are controlled using only 8 data lines on the controller port.
