In the context of public transportation, RDIS gathers information from heterogeneous data sources, such as buses and stations, to provide passengers with timely updates on schedules, delays, and operational changes through user interfaces on web, mobile apps, and onboard displays. Although research has extensively addressed data fusion from diverse sources; challenges such as ensuring consistent and synchronized data delivery across multiple user-facing interfaces while maintaining low latency, remain relatively underexplored in both research and practical implementations.<\/p>\n\n\n\n<p>This thesis seeks to address these challenges by analyzing the specific requirements of public transportation systems, developing tailored consistency metrics, and designing synchronization protocols for RDIS output interfaces. By combining theoretical insights with hands-on experimentation, this thesis aims to propose effective approaches for enhancing data synchronization and delivery in real-world distributed systems.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><\/li>\n<\/ul>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Real-time distributed information systems (RDIS) are designed to process, manage, and deliver data across interconnected components in distributed environments under strict timing constraints.
