Transit
Find out what the street did to your headway.
Buses leave evenly spaced and arrive in pairs. The gap collapses somewhere on the corridor, and the corridor is the part nobody measures.
Headway
The gap between vehicles, measured at the stop rather than modeled.
Dwell
How long the stop itself held the vehicle.
Boardings
People waiting and people who got on. No one is identified.
Two buses arrive together and the next one is empty. You can see it happened. What you cannot see is which block it happened on, whether the stop held them or the traffic did, and whether it happens there every afternoon at five.
All four read the same record. See what we sell.
Find the block that eats the gap
Headway measured along the corridor, so bunching has a location.
Separate the stop from the street
Dwell at the curb, and delay between stops, counted apart.
Size a bus lane before you paint it
What already moves through, by class, at the hour you care about.
Count who is waiting
People at the stop, as a number. Never as anybody.
Followed, not spotted. The same bus from stop to stop, so a gap can be traced along the corridor instead of guessed at from two ends.
Fig 01
Without overlap
The path ends at the edge of the view. What comes out the far side is a new object.
With overlap
The next pylon has it before the last one loses it. One object, one number.
We count people at a stop and we never learn who they are. We do not read plates and we do not read faces, so boardings are a number and nothing else.Our privacy rules
