About this dataset
Why TIDES?
TIDES is a data specification for transit operations data including vehicle locations, passenger counts, and fare transactions.
- For transit agencies, TIDES simplifies and unifies your historical operational data, allowing you to improve data quality, integrate data sources, and create the reports and tools you need to plan and manage service, including use cases like National Transit Database reporting and on-time performance analysis.
- For consultants, researchers, and partners, TIDES simplifies access to transit operational data and allows creation of standard reports and tools across agencies and data sets.
- For national, state, and regional bodies, TIDES enables collecting granular, standardized data from transit providers throughout your jurisdiction, streamlining reporting and unlocking new analysis capabilities without burdensome overhead.
- For ITS system vendors, TIDES makes it easier to give your customers access to their data and allows them to use the data in more ways.
TIDES frees your transit data and gives you more options to turn operations data into information on ridership, passenger loads, fare revenue, vehicle speed and delay, service reliability, and more!
