The California Integrated Travel Project (Cal-ITP) will share about their work to collect, aggregate and improve transit data from the 200+ transit agencies across California.
The California Integrated Travel Project (Cal-ITP) is a State of California initiative to improve the public transit rider experience. Cal-ITP focuses on improving the quality and interoperability of data produced across the State's 200+ transit agencies.
In this talk, we'll share three case studies covering how geospatial data is used at Cal-ITP, starting with demonstrations of public data products visible on the Data and Digital Services group's website at https://analysis.dds.dot.ca.gov. These case studies will cover:
- The standards-conformed public TIDES dataset
- Public transit speed maps
- Cashless payments live dashboard
Along the way, we'll discuss challenges we faced, how we provided assistance and support to transit agencies and vendors, and how our data pipeline operates as a result of those learnings. We'll also discuss technical details including automated data assessment, open data product generation, and cost engineering.
We’ll share the merits of surfacing public datasets, building on top of open data standards, and how each contributes to building a virtuous cycle of continuous improvement across the transit data ecosystem. Our team and work processes can serve as a model for other State DOTs or regions that have a lot of entities within them that produce similar data.
