Grab annual average for segment speeds, find trips that share same road segments

segment speeds

• notebook showing groups we reduce when we move to route-direction from shapes, and look to see whether we lose any trip coverage
  • do we lose n_trips covered?
  • how many rows do we reduce if we have can aggregate by space, within a day
  • check every date we have available, since when we aggregate by time, we'll lose this granularity of check
• Research Request - Segment stability in speed time-series / quarterly and yearly averages #1202

road segment speeds

• initial exploratory work related to finding partial shared roads for operators
• pick 1 Culver City route (route 6), where there are a set of segments where Big Blue Bus also runs service in Westwood
