Carole Brown explains why the 22 and 36 buses aren't on Bus Tracker yet
I found it interesting that on the same day that the CTA board heard from the riding public their thoughts on the 2009 budget, the board chair posted an explanation on her blog about why more buses weren't connected to the Bus Tracker system.
Carole Brown explains how new buses must be outfitted with the GPS eqiuipment needed for Bus Tracker to track.
Then she tells us how a small number of routes don't pass "prediction accuracy testing," including the No. 22 Clark bus. It's actually a very interesting argument about various agorithms involved, including the "prediction algorithm."
Finally, she explains the "
black back holes" in data created where more than 150 buses put in service in 1991 and 1995 are still operating.
