AN INTELLIGENT AMBULANCE CAR WHICH CONTROL TO TRAFFIC LIGHT 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. AN INTELLIGENT AMBULANCE CAR WHICH CONTROL TO TRAFFIC LIGHT -2-
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.
