Get a list of real-time departures for a specific stop_id.
Do not poll this more than once a minute per stop or attempt to retrieve data for every stop.



These are live, stop-centric results based on GPS and the latest information in our system. We've tried to pack as much useful data into the results so you can use this in conjunction with the other methods to piece together all the information about a given bus in real-time.

There are a few things to note about the data provided here. The is_monitored field does not imply you should show the scheduled time! The expected value is based on the last known location of the bus and could still be more accurate. If is_scheduled field is false, the trip element will be blank because this trip was no scheduled previously. It was added supplementary to the regularly scheduled service.

The trip and shape_id depict the trip that the bus will use to pass this given stop; however, this may not be the values for the bus at this moment. For instance, you may see a 5E Green that's 40 minutes out. The trip and shape_id will be for a 5E, but the bus might currently be a 5W Green that will eventually become a 5E! Please keep this in mind when you're mapping results. We hope to be able to provide the current values later.

To get results for all the stops at an intersection, drop the number and colon from the stop_id (ex. IT:1 -> IT).

The vehicle_id is unique to each vehicle and also indicates the date the vehicle was acquired (e.g. 0958 is from 2009).

With the iStop field, MTD is making an exception to our policy of not allowing co-branding of MTD's names or logos. You may use the iStop logo and identify data as such. You may not misidentify any departure as an iStop that is not identified as such through the API. You may not use this name or logo to seek to mislead or misinform your users. You can download the iStop logo as an SVG or a high resolution PNG. Visit our website to learn more about how iStops work.
