Recently, extensive intelligent transport systems (ITS) studies using spread-spectrum communications are under way. Such studies have suggested a calculation/distance measurement method for securing passengers more efficiently in public transportation systems and the like. This method maintains communication between a base station and a small device like a card carried by the passenger. This makes it possible to perform calculation and measurement in real-time. The cards send an individual information in each c/dcard (ID information) in response to the base station. The base station calculates the correlation value by using spread-spectrum signals, then performs the calculations and distance measurements. As a result of a simulation, good results were obtained in the present study.Index Terms-Calculation method, distance measurement method, intelligent transport systems (ITS), spread-spectrum communications.
