| Abstract: | This paper introduces a new Electronic Toll Collection(ETC) design,which adopts infrared wireless communication technology instead of RF wave communication.Compared with RF wave communication,infrared provides several advantages such as wideband,more secure communication and eliminating multipath fading.This system has two key parts:RSU(RoadSide Unit) and OBU(OnBoard Unit).This paper presents the design of hardware and firmware program.The experiment result indicates that the means of implementation can meet the requirement of design.The system also has the flexible and general characteristics. |
