The hardware structure of the project is a model of 4 East/West streets intersecting with a North /South street. The purpose of the project is to control all traffic signal lights installed on all traffic signal boxes. The code is written in Codevision C and simulated with proteus software.
1-Supply voltage 5 V DC @ 1 A
2-An AVR ATmega8 micro controller is used as the main controller
3- Main PCB has all push-buttons, feed seven segment display PCB with data etc.
4-System has one (two digits) LED numerical display to show speed of a car passing between two IR sensors.
5-It has one (six digits) LED numerical display to show the current Time and Date.
6- The system makes use of IR sensors to calculate speed of a passing car
7- 34 LED traffic light signal indicators
8- Turning on off cycle of all traffic signal lights is such if speed of a passing car is 30 km/ hours, the driver receives green light at each intersection located on the main street.
9-Every day, From 24 PM to 7 AM , system functions on its Emergency mode automatically, (E/W streets blinking red signal lights, main street intersections, yellow blinking signal lights).
10-By depressing the Emergency button, the system is forced to function on its Emergency mode.
11-3 push buttons installed on main PCB for emergency mode and setting current Time and Date.
