Most cities in Indonesia have heavy traffic. Unfortunately, any traffic sign violation made things worse. It is common to find that certain traffic congestion started with careless parking, stopping at forbidden spot and many more. This makes violations of traffic signs known as the top 3 of traffic violation that often occur. Such problem has motivate Hilmi Musthafa Albasyir (Electronic Engineering Education), Ryan Julianto (Mechatronics Engineering Education) and Silvia Ramadhani  (Electronic Engineering) to design an Automatic Traffic Sign Detector (ATSD) based on Active RFID sensors to minimize violations of traffic signs and make road users aware of the importance of traffic signs.

According to Hilmi Musthafa Albasyir, ATSD serves to reduce violations of traffic signs due to tree-covered signs or flags, while it can give drivers a warning about traffic signs that are covered by trees, billboards or vandalism. "Hopefully ATSD can be a solution to reduce traffic signs violations as well as educate the public by displaying it on a vehicle speedometer," Hilmi said.

Ryan Julianto said that the materials and tools used to make ATSD are laptops or computers, solder, internet, acrylic, 3D printing, NRF, Arduino, TFT LCD, and GPS sensors. "ATSD uses active RFID sensors that are designed to work during the day and night," Ryan said. "The use of Acrylic and 3d print materials is chosen because it is resistant to heat and rain so it is not easily damaged, and is easy to form," he said

The trial results show the effective distance used is 7 meters before the sign and 7 meters after the sign. Therefore, at a distance of approximately 6 meters, signs begin to be detected and the screen on the LCD changes to display the detected signs. At a distance of 3 meters before the sign, the LCD still displays the detected sign because this distance is still the effective distance set by the ATSD transmitter. It is the same with a distance of 0 meters or exactly on the detected sign or after the vehicle mounted with an ATSD scanner passes through the sign as long as it is still within the effective range set. When the vehicle mounted on the ATSD scanner passes 11 meters from the sign, the ATSD scanner does not detect any signs and will stop displaying signs. This work won funding from the Directorate of Higher Education in the Student Creativity Program in 2019. (Dedy; Tj.Lak)
