Designing Emergency Vehicle Detection System with Wireless Bluetooth Based on Arduino

Abstract

Congestion is a problem that arises because of the many vehicles on the road. One of the bottlenecks that is often encountered is at a crossroads. From several vehicles, there are emergency vehicles that must be prioritized. Therefore, this research develops a system using Bluetooth technology that gives priority to emergency vehicles to cross the junction. This system works is the first Bluetooth module before the junction with a distance of 500 meters detecting it with autopairing and autoconnect on the Android Bluetooth that has been made. This system uses Arduino Mega as its data processor to make the traffic lights output freeze to the green light, then the traffic light will return to normal when the second Bluetooth module after the junction with a distance of 100 meters detects Android Bluetooth. The results of the study are very helpful when the lane is jammed, but for empty lines this system has a maximum limit at speeds not exceeding 81.43 km/h because the detection distance limit of the Bluetooth connection is only 50 meters
