Title: Wireless ambulance based traffic light control

WIRELESS AMBULANCE BASED TRAFFIC LIGHT CONTROL.Literature Overview: This project is designed to control traffic light with wireless technology. In this project cell phone which is operated by a person in ambulance car is interfaced with microcontroller through Bluetooth Technology to control the traffic light so that ambulance crosses the traffic junction.Objective: The objective of this project is to control the traffic light so that ambulance crosses the traffic junction and patient will reach hospital without time delay for better treatment. DescriptionWorking: This project is designed on the basis of wireless technology. In this project traffic light is controlled by cell phone which is operated by a person in ambulance car with the help of Bluetooth. In this project cell phone is interfaced with the traffic light microcontroller, and traffic light controlled when a signal is send to microcontroller through cell phone. Then microcontroller changes the traffic signal according to ambulance.Block diagram:
