The paper introduces the research to develop an active radio frequency identification (RFID) - based national traffic information collection system (TICS) in ubiquitous environments in order to renovate the integrated national traffic management systems. The study of RFID - based traffic collection system mainly focuses on: (i) 2.45 GHz active RFID readers and tags; (ii) RFID middleware and DB structure, and application S/W; and (iii) network architecture to deploy TICS nationwide. The paper investigates and analyzes possible network architecture for TICS when it is deployed nationwide, and suggests efficient network configurations. For communication between user terminals in vehicles and the central system, WiBro (mobile WiMAX) and high speed downlink packet access (HSDPA) networks are recommended and Life Cycle Costing (LCC) evaluation is performed for elaborate exploration of WiBro networks.
