The Portal Transportation Data Archive is a ~2TB PostgreSQL database that has been in existence since 2004. Kristin will demonstrate the current state of Portal. She will discuss the various technologies used to collect the data and the complexities of getting the data from the sensors to the database. She will also discuss her experiences working directly with local transportation agencies (ODOT, Metro, Trimet, Cities of Portland and Vancouver) to produce a web site that is useful in their day-to-day operations.
