I put my last post on free and open source software for transit systems out as a lifeboat, thinking it would bob on the waves of the Internet until someone -- far from now -- might read the post and wonder. I didn't think I'd get a reply so quickly.
So I've looked further for options.
- I asked the American Public Transportation Association's point person if she knew anything. Not FOSS, but here's their list of bus management software. Which, I suppose, might help a willing amateur like myself ask the right questions in future.
- I did find this Linux Insider article from March 2008 about FOSS traffic management solutions, which cited a project at the University of California, Davis. Not transit, but I'd think there's some room for overlap
- That UC Davis program and this project especially. Again, to inspire
- Then there's the legal imperative in a number of European and Latin American governments to use fee and open source software where available. So perhaps something is out there, but not in English.
I'll keep looking.
