High-load transaction systems such as the IC (Integrated Circuit) Card Ticket System require high performance, high reliability, and service continuity. However, the wireless communications have a problem that higher performance at the gates results in lower reliability in the data. The solution is the Autonomous Decentralized Architecture, in which "IC cards," "terminals," and a "center server" are designed as the autonomous nodes. Based on the architecture, two technologies have been introduced: "Autonomous Decentralized Fare Calculation Algorithm" for high performance and "Autonomous Decentralized Data Consistency Technology" for high reliability. This paper looks into the Multi-layered Data Consistency Technology which assures service continuity, using heterogeneous data fields with various time ranges. Appropriate values are considered through theorization, modeling, and simulation.These conditions are used in the practical "Suica" system at East Japan Railway Company and the system is running satisfactory, without any fatal errors.

The public transport IC (Integrated Circuit) card widespread used provides a new data source for collecting passenger flow information. The effective information of bus traveling can be obtained from IC card data by using the data mining technology . The attraction weight coefficient OD calculation method is used for obtaining the basis public transport passengers flow data. Based on these, this paper analysed the data mined and discusses its application according to the characteristics of urban public transportation. The effective information of passenger flow distribution was used for arranging the Public Transport operation mode. This paper makes up the shortfall that IC card data is only used in calculating the distance but not in mining meaningful information about the arrangement of route operation mode. Finally, by real case study of two lines of Beijing Public Transport Group, the feasibility and practicability of the method proposed were verified.
