A second comparison is for the outer portion of the corridors. In the rail corridor the zero
and one auto ownership rate was 49.0 percent in 1980 and 47.9 percent in 1990, a 1.1
percentage point decrease in share, as compared to a rate of 45.4 percent in 1980 and 44.5
percent in 1990, a 0.9-percentage point decrease in share for the parallel bus corridor.
However, there is an interesting difference when comparing two-vehicle households.
Two-vehicle households grew by 1.4 percent in the rail corridor, while two-vehicle
households grew by 4.8 percent in the bus corridor. This difference might represent the
beginning of a self-selection or residential-sorting process wherein households choosing to
live in the outer rail corridor are less in need of two vehicles than if they were to locate
elsewhere.
of zero- and one-vehicle households. Both shifts are detrimental to transit ridership, and
LRT is not reversing this powerful trend of increased auto availability.
