Long ago, when all transit data was collected manually by students with clipboards, I did a few studies that watched what happened on a bus or streetcar/tram in normal operation and counted the seconds of delay associated with each of the following factors:
- Being stopped at signals.
- Being stopped or slowed by traffic.
- Being stopped or slowed by accidents.
- Normal-pace boarding and alighting.
- Wheelchair boarding and alighting.
- Conversations with the driver that interrupt boarding/alighting.
These studies are usually done deep inside of transit agencies and often not published (not out of secrecy or shame, but just because they're very technical.) Have any readers seen or done any studies like this? I'd like to pull some typical data for a couple of them.
