Abstract
The limitations of satellite navigation systems such as global positioning system (GPS) in indoor settings (tunnels, urban areas, etc.) are due to the deflection and distortion of satellite signals by neighboring buildings which degrades the performance of GPS. Alternative methods for vehicle tracking need to be developed for such settings. The main objective of this paper is to propose a design system that utilizes Bluetooth for traffic tracking. In our system, low-energy-enabled Bluetooth (BLE) modules serve as beacons, when such modules are placed alongside the road. BLE modules constantly advertise the information about their position to the passing BLE-enabled vehicle. When this BLE-enabled vehicle receives the position data, it transfers the data directly to the microcontroller. Moreover, the microcontroller displays the position on the LCD module. Additionally, it also saves the position data directly on the SD card for comparison with data gathered through GPS receiver.
