Android and Cloud Based Traffic Control System

Traffic congestion has become a major problem in the urban cities, and it is mainly caused due to an increase in population which causes traffic congestion. It therefore becomes a problem for the emergency vehicles for example, an ambulance, to arrive as early as possible to its destination without appropriate traffic control system. So it was essential to design a traffic control system which will be controlled by an android mobile device via the cloud environment. In this paper we explored other intelligent traffic light systems and other transportation systems. This system has to allow the Android mobile device (emergency vehicle) to override the normal operation of a traffic signal. An efficient and cost effective system which can solve this problem is an Android and Cloud based traffic control system using the GSM module. The system comprises of five stages which are Android mobile device, GSM module, MQTT (IoT) for Arduino IDE, Arduino Uno microcontroller and traffic signals. The developed system has allowed the Android mobile device (emergency vehicle) to override the normal operation of a traffic signal.
