Re: B44 Progress Report Released

Posted by Stephen Bauman on Fri Jul 8 22:52:48 2016, in response to Re: B44 Progress Report Released, posted by BrooklynBus on Fri Jul 8 20:57:27 2016.

they added service for fewer passengers. Hardly makes any sense.

Average boarding and exiting times increase by half a second per passenger, when there are standees on the bus. If you are trying to show that dwell times decreased, it's best to use buses with low load levels.

The service levels varied throughout the period. Here's a csv suitable for pasting into a spreadsheet for various weekdays from the conversion to SBS.

You can see they increased SBS service levels starting in Oct. 2014. They did not reduce the level until April 2016. I wonder when they took the average dwell time measurements for the report :=)

The decrease in service levels during the summer months is pretty standard. School is out.
