All Aboard: Real-Time Transit Data Visualization with Oracle APEX
December 2, 2025 | 11:00 AM CT
Public transit data is rapidly growing as many transit agencies publish information and encourage developers to create innovative applications. In this session, I will demonstrate how I built an Oracle APEX application to consume GTFS real-time data and present it effectively using APEX map regions and Oracle Spatial/Graph features. I will also explain how I leveraged Oracle Autonomous Database 23ai MLE functionalities to parse the protocol buffer format of GTFS real-time data. The session will include a live demonstration of the application using real-time transit data from a U.S. transit agency.
Presented by Oscar Javier Gordillo Roncancio, Oracle APEX Developer, Consultant at Fire Department of the City of New York.
This event is co-hosted by the New York Oracle Users Group (www.nyoug.org) and Oracle Professional Services firm, Viscosity North America (www.viscosityna.com)
