San Diego's New La Jolla MTA Line
The nine-station La Jolla line will run 11 miles from Old Town to UCSD. SANDAG estimates the new line will attract 20,000 new transit riders a day.
I find it hard to see the 20,000 "new" transit riders a day within this locale. Maybe a brunt of it would be students going downtown but unless it actually stretches further North, I think this could easily be another 78 corridor ridership-less mode of transportation.
