It's been 18 months in the making...

...but I have finally submitted my second bus research paper to Physical Review E for their consideration. For those who are curious, you can find a copy here: http://arxiv.org/abs/0709.0078

I've been studying bus route models since before I graduated from the University of Chicago, and published my first solo paper on buses in 2003. The research in this paper comes mostly from last spring when we first moved to Dallas: I gave a talk on my research in April 2006 at SMU, changed directions completely due to some comments made at that talk, and then talked about my new direction at MIT in May. I've added little bits since then, but most of the delay has been my trying to find time/energy/motivation to work on the paper in between teaching gigs.

I've already gotten good reviews from civil engineers at MIT and the University of Arizona; let's hope the physicists agree. :)
