Stop Frequency and Collinearity Screen#
Evaluating Collinearity#
Transit agencies have wide flexibility in designing their networks. Where we determine multiple routes are providing a combined service, we combine their frequencies on the shared segment. See our README for a longer explaination.
We use combined or single-route frequencies as appropriate for our spatial pathway for locating bus intersection Major Transit Stops.
The branching pathway uses exclusively single-route frequencies, so we always calculate both.
Current Analysis Date#
November 05 2025 (Wednesday)
If we are missing data on that date for a particular operator, we will patch in data from the previous three months. Currently patching in:
{'2025-08-20': ['eTrans Schedule', 'Roseville Transit GMV Schedule'],
'2025-09-24': ['San Juan Capistrano Trolley Schedule',
'Culver City Schedule'],
'2025-10-15': ['Yolobus Schedule',
'Go West Schedule',
'Bay Area 511 Angel Island-Tiburon Ferry Schedule',
'El Monte Schedule',
'Nevada County Schedule']}
