RT Journal Article T1 Bike sharing systems data interoperability by a unified station status concept and big data solutions A1 Márquez Saldaña, Francisco A1 Aranda Corral, Gonzalo Antonio A1 Borrego Díaz, Joaquín AB The impact of bike sharing systems (BSS) on urban mobility, and their study as part of theoverall transport system in smart cities, has attracted significant academic interest inrecent years. However, the lack of historical and standardized data in current service toolshinders the analysis and improvement of these platforms, i.e. by reusing technical databasedsolutions. Big data nature (in volume, variety and velocity) of collecting BSS historicalinformation must be also addressed, in order to take an integrated perspective.This paper describes an integrated solution to this challenge by (1) proposing a unifiedstation status concept for recording historical information, based on the identification,study and unification of common relevant fields found in almost all BSS data warehouses,and (2) implementing a big data-inspired ETL infrastructure together with a storage optimization,methodology which not only allows to access and collect previous definedconcepts but also overcomes existing big data challenge when storing BSS information.The system also consumes other external relevant information, such as weather factors,which have been aggregated, enhancing stored knowledge, with KPIs and statistics. Thedeveloped solution illustrates how it can manage over seven years of data from twentysevenBSS, serving not only machine-to-machine communication but also human-computercommunication and enabling data-driven solutions PB ScienceDirect SN 2095-7564 SN 2589-0379 (electrónico) YR 2025 FD 2025-04 LK https://hdl.handle.net/10272/25566 UL https://hdl.handle.net/10272/25566 LA eng NO Márquez-Saldaña, F., Aranda-Corral, G.
