Abstract

Congestion is a normal situation in our daily lives. People need to face this problem especially when driving during peak hours in big cities with lots of traffic lights. They still can plan their route earlier to avoid traffic jams, differently with emergency vehicle with unpredictable time travel. The purpose of this project is to develop and design a new technology that will overcome this problem. The current study used sensor to detect the number of cars on each side of the junction and gives long time for green lamp of traffic light to reduce the congestion. However, there is still no priority given to the emergency vehicle by the system. Thus, this project will introduce a bypass system with the development of GPS and XBee wireless communication to make sure that emergency vehicle keeps moving at a traffic light junction although they have longer queue due to saturation of traffic flow. GPS installed in the emergency vehicles will capture their current coordinate and XBee will transmit it to the nearest traffic light controller that also use XBee receiver. The traffic light controller will be triggered to the keep green light ON and at the same time turning ON the red light for the other phase of the junction until the emergency vehicle passes through traffic light. The system in this project is portable and can be easily used or transferred into different types of emergency vehicle. In order to support the green technology, this device is equipped with a battery and a solar panel to auto re-charges its battery when in used.
