IoT Based Real Time Data Collection for Dynamic Road Weight Measurement

Abstract

Traffic congestion is an inevitable problem for metropolitan cities around the globe. A new and dynamic internet based decision making tool for traffic management system (TMS) was proposed and implemented in our previous work. The tool uses weather, road and vehicle related information and generates the routing decision. Thus, real-time data collection is important. There are many web portals hosting real time continuous weather data streams. However, their coverage is limited to city level congregate information and location/area based information is necessary for real time TMS decision. In addition, there is not a single web site that hosts real-time road and vehicle information. Internet of Things (IoT) can be a solution for this circumstance. So, an IoT based framework is proposed and implemented with several remote agents. Agents are securely (session management) interconnected with a cloud server and able to collect or exchange TMS data among themselves through GSM/GPRS/Bluetooth communication channels. Each agent is an embedded device with integrated sensors (including DHT11, Raindrops Sensor Module), Arduino microcontroller and GSM/GPRS/GPS Bluetooth enable modules.
