Need the list of vehicles data running the trip per day

[Shubham Dhanetia]

Hello team,

Is there any way to get a list of vehicles running on a particular date along with their trip ids. 

I know there is trip updates rt gtfs feed API, but I believe we can't see all the vehicles if they are not running at that moment. And so only option would be to keep polling the API all the time of the day and store it in database and get the distincts vehicle ids running on a particular day. Please let me know if there is any better option ?
