SF MUNI Transit Delays, Visualized
×

San Francisco's MUNI system has a stated on-time performance of 59.3% , which counts vehicles that run within 4 minutes of schedule. However, OTP is only one factor in perceived transit quality.

This visualization expresses many transit performance metrics, including:

  • Frequency of scheduled service
  • Maximum headway between vehicles
  • Catastrophic failures and delays.

Delays: Vehicles become behind schedule due to street traffic or other factors.

Bunching: Late vehicles get later as they need to pick up more passengers.

Infrequent Service: Large headways due to less vehicles in service than scheduled.
