Read the case studyTransitOPS is a non-partisan, not-for-profit team of technologists, urbanists, and transit advocates. We help public transit agencies harness modern, open-source technology to deliver better service. With a focus on equity and affordability, we work to ensure every rider gets the information they deserve.
Understand where riders need better information. Use research with riders and staff to focus on the changes that will help them most.
Understand how your systems and data fit together. Identify duplicated work, gaps in information, and practical ways to improve what your agency already has.
Put open-source systems into service with a team that understands transit. Keep control of your data, your tools, and the decisions about what comes next.
Public transit agencies continually generate data as they provide service to riders. Frequently this data exists in separate silos, making it difficult to combine to support better service.
The TransitOPS Data Platform provides the infrastructure and software to ingest this data, process it into consistent formats like GTFS and GTFS-RealTime, and publish it to riders and staff.
We work toward transit that is accessible, dependable, and affordable. Open standards and shared tools give agencies more control over how they get there.
