GTFS for summer 2023 (2023 Q3) is out.
As such, the MBTA frequency map I can update it again.
Weekday changes aren't shown on this map as weekday service is higher than Sunday service, and plotting rush hour routes gets complicated due to differing service schedules and midday gap.
Due to BNRD being on hold, this is an additional update. I will only be updating this map until BNRD phase 1 begins.
Map changes (based on adjustments to bare minimum Sunday service):
Frequency increase:
* Orange Line up from 80 to 106 trips (Every 15 - 20 minutes -> Every 10 - 12 minutes) (>=101 trips, >= 81 trips)
Frequency decrease:
* Blue Line down from 124 to 102 trips (10 minutes or better -> Every 10 - 12 minutes) (< 121 trips)
* SL1 down from 124 to 107 trips (10 minutes or better -> Every 10 - 12 minutes) (< 121 trips)
* 111 down from 106 to 92 trips (Every 10 - 12 minutes -> Every 12 - 15 minutes) (< 101 trips)
Routing change:
* 134 early morning and late evening extension from Medford Square to West Medford @ Winthrop St & Playstead Rd.
* Winthrop routing for route 713 shifted 1 block westwards
Due to frequency changes, there is no longer any route with more than 121 trips on Sunday, and therefore, no route with sub-10 minute frequencies or better. Only the Green Line trunk with multiple interlined branches qualifies as such. The maximum trips on a single route is 118 trips (GL E) on Sunday.

Comparison now (Q3 2023) vs. Amsterdam. It would look worse if the Orange Line was kept where it was (80 trips Q2 2023).
