Control System for Smart Traffic Signal using LTE, GPS, RFID for Ambulance

Abstract

Nowadays, Ambulance services are the most affected by the Traffic Jams. This can threaten the health state of the person within the ambulance. It can be resolved by using the Control System for Smart Traffic Signal using LTE, GPS, RFID for Ambulance. This system creates a connection between the ambulance and the traffic signal. So, as to assist the ambulance for a stop free travel to the destination. This system uses Radio Frequency Identification (RFID), Global Positioning System (GPS), Long Term Evolution (LTE) as its key components to implement the control system. The GPS helps in live tracking the ambulance movement in order to change the traffic signal only when the ambulance is nearby the traffic signal. Once the GPS confirms the ambulance is nearing a traffic signal, the cloud instructs the change in traffic signal’s mode and the ambulance’s lane is granted green signal. Once, the ambulance crosses the signal, it reverts back to its original flow. The RFID tag assists in confirming the passage of ambulance from the traffic signal. Also, this method warns the upcoming signal and changes their signal time based on factors such as ambulance speed, distance and expected arrival time which helps in clearing out the traffic in advance. This is continued until the ambulance reaches its destination hospital. All these processes happen without any human intervention.
