Development of the Flexible Traffic Control System Using the LabView and ThingSpeak

A system for controlling a traffic flow within loT environment is described. The system has a modular layout and is divided into the low level (driver) and high level (the server part). This separation enables to provide the flexibility property for the system with the ability to adapt to different roadways. Moreover, installation costs are reduced by using the inexpensive equipment, as well as all computing load is transferred to the cloud. The hardware such as Raspberry Pi, BeagleBone, Arduino board and webcams are implemented for lower level, the HW model is determined by the needs of road marking. The LabView is used for developing the low level because it provides many operation functions and the ability to transfer directly a code from a PC to a microcomputer. The ThingSpeak is selected as the high level (SW server, cloud) because it has an open source for storing and receiving data using HTTP and MQTT protocols within IoT environment. Moreover, the ThingSpeak has an integrated MATLAB support, and such property enables to improve Control System productivity by combining LabView and MATLAB.
