Transcript of Project
Do you have ever crammed at Red light in a junction even without a vehicle in joined roads?
Do you have seen traffic lights give much priority to roads with less number of vehicles?
So are we…
Then we determined the importance of having an intelligent traffic light system.
Older systems uses weight as a trigger mechanism.
When a vehicle comes on to lever it completes the circuit and switch on the system.
This is also little odd to use with modern light weight vehicles.
Weight triggering mechanism
What are we looking for...
Our aim is to develop a proper system to reduce the time wasting at traffic lights due to unfair division of time for different traffic flows.
Identifying different stages of the problem we found.
Finding solutions for mentioned problem.
Applying solutions to single system with microcontroller programming.
Developing the device.
Evaluating the activity of the system in various situations.
Finalizing the project with the documentation.
We identified IR waves as the best media to trace the presence of vehicles and the length of traffic flows.
People who are benefitted
Whole economy of the country
Process of the Application
IR LED -> Vehicle -> IR Reciever -> IC -> Traffic Light
IR waves reflected from vehicle surfaces
Traffic lights is the interface to the user and can be known as the output of the process.
Vehicle identification modules
Traffic light system
Major stop switch
Major Components will be needed
•Schematic of a IR transmitting circuit
•Schematic of a IR detecting circuit
•Powering up a Lamp
Softwares and tool suits will be used
MP Lab IDE with PIC Basic Pro Tool suit and Mikro C toolsuit
Proteus Pro as the simulation software
PIC kit 2 as the EEPROM writing software
•Manual priority setting switch can be implemented.
•Possible to develop for a 4 way junction too.
•More IR sensors can be used to indicate the presence
Detemining the number of vehicles
Distance between two sensors represents 2-3 conventional size vehicles.
Intelligent Traffic Light System
•What Aussies have done…?
Identify presence of vehicles in roads with modern cameras and set traffic lights work according to the behavior of traffic flows.
But the inconsistency of that system to Sri Lanka is it’s high cost.
Current solutions for the problem
Overview of the Presentation
Our Aim & Objectives
•Time allocation for various number of vehicles
