More parking systems are developing toward automatic identification (ID) and control, where infrared (IR) technology is a low-cost and the most used approach for data transmission and ID. However, interference is caused by sunlight or two neighboring vehicles in a conventional IR-sensor-based parking system; therefore, a new methodology using a split transmitter/receiver (TX/RX) installation on a roadside unit (RSU) is proposed in this paper. The TX and RX modules are placed upward and downward on an on-board unit (OBU) device, respectively. Therefore, the proposed parking system can reduce the impact of sunlight on the RX module of the OBU device and reduce the signal interference caused by two neighboring vehicles in the sensing zone. Furthermore, the ID stability of the conventional RSU system can be increased.
