Inteligent Traffic Ligth System

For the Semester 4 of the Computer Engineering Department of  University of Moratuwa, we learn a subject call Micro-Controllers and Applications. The aspect of this to learn the way of handling Micro-Controllers in their limited environment. For the project of this subject some of we have been asked to build a intelligent traffic light system.To describe it's functionality read this,

  
 
  • Control of the road traffic on junctions :
    Up to maximum of 4 roads are intersecting with 4 pedestrians crossings in each road, near the junction. This will be the extreme, but system will be able to control all the other subset of junctions.
  • Dynamic priority level for roads :
    This system will be able to sense all the vehicle movements through the junction.After sensing these movements, the system will adjust its timing parameters automatically to give the higher priority to roads which have much traffic level.
  • Ability to configure system easily after installation:
    After installing the traffic light system in the roads, the configurations can be changed by plugging a simple interface to the system.
  • Manual Override:
    When a Police Officer does traffic controlling, he will be able to control all the traffic lights using a remote control device.
  • Fail Safe :
    If something goes wrong, the system should be able to move into state which will stop all the movements of vehicles and people, which will cause further damage.
  • Energy Saving:
    Should be able to control the intensity of the lights in the night and day time.
  • Automatic roll back to auto mood:
    If system has been changed to manual mood and if there are no commands issued to the system for a particular time period it switches back to auto mood.
  • Can be configuring according to the place of installation:
    The abstract system is constructed to install in a junction which has 4 roads. But after doing few steps of configuration it can be used in any kind of place.
Our design was done based on the above functionality. I like to describe the steps we go through, First of all the below diagram shows our basic block diagram of the design.
