Origin/destination matrices for Los Angeles?

[daniel....@gmail.com]

Does anybody know what data Metro uses to evaluate how well its lines are meeting demand?

I've seen http://www.metro.net/about/library/library-research/research-tools/transportation-statistics/
and http://www.metro.net/news/ridership-statistics/
and I've seen the promising-looking data at
http://www.fhwa.dot.gov/planning/census_issues/ctpp/
but I haven't heard about LA County Metro using
origin/destination matrices.

(Nashville's MTA has used them, see http://www.nashvillemta.org/PDF/Part4_Appendix_A_C.pdf )

Thanks,
Dan

p.s. Ahh, Usenet, it's been a long time!
