Summary:
The standard of 700MHz band intelligent transport systems (ITS) including Vehicle to Vehicle (V2V) communication and Infrastructure to Vehicle (I2V) communication has been published in Japan [1]. In response to this situation, Pedestrian to Vehicle (P2V) communication which can coexist with I2V and V2V communication on the same frequency is required for pedestrian's safety. This paper proposes three access methods which are suitable for this system. They are evaluated by static simulation in which a roadside Unit (RSU), many on board units (OBEs) and many pedestrian portable terminals (PPTs) are distributed throughout a large intersection. Moreover these methods are tested using radio equipment in real field. Simulation and field test results show PPT can coexist with present system if using our proposal.
