Open Trip Planner for NYC

[Connor Riley]

has anyone deployed open trip planner for NYC? It seems like they have 2 subway gtfs static files

Regular GTFS: This file represents the "normal" subway schedule and does not include most temporary service changes, though some long term service changes may be included. It is typically updated a few times a year.

Supplemented GTFS: This file includes most, but not all, service changes for the next seven calendar days. Generally, the 'simpler' the service change, the more likely it will not be included. Beyond that period, service changes will not be included. It is updated hourly.

if I wanted to use the more accurate supplemented gtfs, and update hourly, what is the best way to accomplish that? I assume the graph build times are long -- how can I minimize the time it takes between when they release a new static gtfs file and the time my open trip planner instance is ready for requests?

How critical is it to update each hour? Is the MTA changing the static GTFS for the next hour or for a few days in advance? Can I get away with only updating each day?

Thanks in advance!
