This document describes a project to design an intelligent ambulance car that can control traffic lights. An infrared transmitter would be installed in ambulances to send a signal to receivers at intersections. The microcontroller at intersections would detect the ambulance's signal and switch all lights to green in the ambulance's direction and red in other directions, clearing a path for the emergency vehicle. The goal is to reduce waiting times at lights for ambulances responding to emergencies to save time. Block diagrams and interfaces like sensors, displays and buttons are discussed. Software like compilers and debug tools would be used to program the microcontrollers.

PROJECT DEFINITION / SPECIFICATION
PROJECT TYPE
Micro controller (AT89C51) hardware design with software
development (Device Driver) .
PROJECT DESCRIPTION
•
To Design a circuit of a microcontroller based intelligent ambulance.
•
Develop new ideas to implement this circuit purposely.
•
To study the circuitry and different types of components & timer, IRLED photodiode, 89c51 microcontroller and programming in assembly
in the circuit.
Traffic density on roads in big cities like Delhi, Bombay, Calcutta, and
Madras has become so high that it requires a lot of planning for smooth flow
of the traffic on the roads. Therefore the traffic lights have been installed at
almost all major traffic crossings in these cities.
The given project is a basic traffic light control system using
emergency case as an ambulance, fire brigade etc. That drives to reset all
traffic lights, switched on green light at ambulance side and other three side
red light. All emergency vehicles have a transmitter which transmits the IR
signal (RF). Transmitter section is used into ambulance car which controlled
to traffic light.
This module emits modulated infrared light. IR-LED is
connected in series for more range and wider directivity. The module can
transmit IR rays up to few meters without use of any external lens.
Traffic light has a receiver.
The receiver uses infrared module
(photodiode). The output of the photodiode is connected to microcontroller.
Microcontroller is wired here in time delay and switching mode.

3. AN INTELLIGENT AMBULANCE CAR WHICH CONTROL TO TRAFFIC LIGHT
Traffic in a city is very much affected by traffic light controllers. When
waiting for a traffic light, the driver looses time and the car uses fuel. Hence,
reducing waiting times before traffic lights can save our European society
billions of Euros annually. To make traffic light controllers more intelligent,
we exploit the emergence of novel technologies such as communication
networks and sensor networks, as well as the use of more sophisticated
algorithms for setting traffic lights. Intelligent traffic light control does not
only mean that traffic lights are set in order to minimize waiting times of
road users, but also that road users receive information about how to drive
through a city in order to minimize their waiting times. This means that we
are coping with a complex multi-agent system, where communication and
coordination play essential roles. Our research has led to a novel system in
which traffic light controllers and the behavior of car drivers are optimized
using machine-learning methods.
