A module is a static website, built on the VTFS API, which provides a window into some aspect of a transit agency's operations. Generate a flexible report on historical data, vizualize the current state of the system... the possibilities are as broad as the API. Agencies can upload modules into your custom VIZ instance to have reporting at your fingertips.
If you've developed a VIZ module and want it included here to share with transit agencies and developers, please contact us. You are welcome to submit both agency-specific and general modules. Keep in mind that the latter is more likely to be useful to multiple agencies.
