This paper presents a research work on an embedded system called Traffic Control Device (TCD) which is implemented as a prototype on a four way road with loops for controlling vehicle and traffic system. In the practical state, this device able to count various types of vehicle such as car, bus, cargo etc by using ultrasonic ranging detector (sonar) covered by wireless sensor networks (WSNs) and check the permitted vehicles based on Vehicle Detection Algorithm (VDA). The system is also capable to demonstrate the number of the vehicles along with their types on a display at the entry point of the road. By notifying this information it can be easily understand whether the road is busy or free. In this paper, the presented solution is given for 3 different types of vehicle; the model of the hardware configuration is flexible enough to get a better performance.
