Efficient Ambulance Controlled Traffic Light System
Abstract and Project Vision : In this project we are using Radio Frequency Electromagnetic Radiations (RF-EMR) communication to implement the efficient system to control the traffic lights by the ambulance in case of an emergency. RF-EMR radiations are strong enough to send a signal to some device at a distance of atleast 50 to 60mtrs.
The project has been chosen to save human life which is the most valuable and costliest thing in this world. And as per the design of the project it is very much feasible in long run in real time applications.
Implementation: All the roads of a crossing having traffic lights will be distinguished as N-North, S-south, E-East, W-West in order to differentiate between different roads and each road will be having the particular symbols(N, S, E, W) at a distance of atleast 100mtrs from the crossing . Each ambulance will be having 4 buttons viz. N, S, E, W. Suppose an ambulance is coming from North(N) side can see a N-syambol at a distance of atleast 100mtrs from the crossing, so in order to make the traffic light green, it can press the button N.
Each direction will be associated with some binary number say
N - 00
S - 01
E - 10
W- 11
So on pressing the particular button the equivalent binary sequence will be sent to the crossing and the respective traffic light will become green.
In case to avoid confusion between two ambulances coming from different directions, each ambulance will set some priority (say pregnant lady will have higher priority than a patient having only fever) and will be given preference according to that.
In case of same priority FCFS (First Come First Serve) system will be followed.
Challenges and limitations: Various limitations are there like having an efficient communication between the traffic light and ambulance and particularly setting the priority of the ambulance.
Software Tools being used: National Instruments LabVIEW and toolkits
Hardware tools being used: To implement this application we are using the Arduino (UNO) microcontroller and the RF transmitter and receiver. The Arduino will be used to implement the serial communication between the LabView and the RF receiver.
Estimated Timeframes: Implementation in NI LabVIEW( 1 month) and Hardware Implementation (15 days approx).
