An Internet of Things (IoT) based Smart Traffic Management System: A Context of Bangladesh

With the fast growth of population, traffic congestion monitoring and control has become a great challenge. Increasing vehicles creates lots of problem like time wastage, fuel wastage, air and sound pollution, even death by getting stuck emergency vehicles. This paper proposes a real-time traffic management system (TMS) using the Internet of Things (IoT) and data analytics. Ultrasonic sensors are used to measure the traffic density. After analysing the sensor data, system controller sets traffic signal time by traffic management algorithm and also sends data to a cloud server through a Wi-Fi module. The proposed system can predict probable traffic congestion in the intersection point. If an emergency vehicle is detected, it gives priority, i.e. high signal duration to pass the intersection. In case of the signal violation, the system can identify the vehicle and charge a fine that is paid through Traffic Wallet mobile app. This proposed system is cost-effective, very simple to install and easy to maintain.
