Abstract: The problems and efficient in existing intelligent transportation system (ITS) models are studied and the significance of the model and architecture of ITS under internet of things (IoS) are also discussed. By the research status at home and abroad about the relationship between IoS and ITS, the necessity of IoS technology introduce to ITS is explained first. Then, based on logical structure and physical model of ITS, the ITS structure model under IoS environment is established. Furthermore, the system architecture on a prefect and comprehensive ITS information system acquisition system is formed. The design principles of system demand, overall design, function modules design, database design are described in detail. The parts of key modules in system are introduce and tested. The tests results show the acquisition system can effectively monitor real-time of vehicle speed, real-time traffic of road vehicles and obtain effective information of vehicle and road environment. It can also send the information acquired via internet or GPRS network to data processing centre, for future process and intelligent decision of ITS.
Keywords: intelligent transportation system; ITS; internet of things; IoS; information acquisition; GPRS; communication.
