Find bounding box and convex hull of agency coverage (as WKT) for a OneBusAway TDS.
from mustaine.client import HessianProxy
from shapely.geometry import box
from shapely.ops import cascaded_union
service = HessianProxy("")
agencies = service.getAgenciesWithCoverage()
boxes = []

This Gist contains a script and supporting files for building a OneBusAway GTFS bundle with data for all agencies in the Baltimore/Washington area that have publicly released their data.

Configuration parameters come from two sheets in a Google Docs document:

The dependency on Google Docs could easily be removed by removing that part of and using a locally-maintained CSV file instead.

Recently (as in, over the past few months) the WMATA BusPosition feed has been behaving anomalously.
There are three observed problems:
1. The feed doesn't include the entire fleet - during the weekday rush hour we'd expect to see close to 900 buses, but this morning the feed returned fewer than 250 vehicles.
2. Bus positions return the wrong trip, or are lagging badly. Look at this example:

GTFS-realtime test harness for frequency-based trips

GTFS-realtime test harness for frequency-based trips


This is a Python-based test harness which can be used to simulate a GTFS-realtime feed with trips on a frequency-based route. Specifically, it simulates arrivals on the AirBART route (obtain BART GTFS here), at the AirBART_OAK stop. For convenience, the script simulates two vehicles, which are perpetually three and seven minutes away, respectively.
