D6.4-Requirements and definitions on Data Bases for Regional Lines (Alpha Release)

This report encapsulates the experiences with data collection for Task 6.3 in Work Package 6 (WP6) of Flagship Project 6 FP6-FutuRe and is referred to as Deliverable 6.4. Task 6.3 involves the mapping of databases needed for various use cases within the broader context of WP6. WP6 involves specification of customer services in the context of regional rail, e.g. a multimodal travel solution including occupancy forecasts. The subsequent task corresponding to T6.3 is T11.3. The data mapping is targeted in T6.3 and the mapped data will be made available for the use case implementations in T11.3. The data on demand and supply related to railway infrastructure is required for proper conduct of operations. For example, one should know the demand and supply statistics before operating new trains or constructing new lines between two locations. The main sources of data for the supply side of railways can be identified as transport operators, infrastructure managers, and ticket vendors. Meanwhile, the demand data can be acquired from the ticket sales and passenger counts. These sources are not limited, as data on demand and supply can be generated by simulation methods, as done by researchers. Additionally, this report discusses the differences between static and dynamic data streams, focusing on their updating frequency, as well as the format and availability of these data streams. The need for data simulations and data validation is also discussed.
