JM: Instead of cost in $ for the right-of-way, one can figure the "cost" in
terms of general road capacity foregone by the ROW taking. In the case of
the Orange County (CA) Centerline elevated light rail system, for example,
it was computed that at average utilization for these streets, the one
lane x 24.7 miles length taken from surface arterial streets for the
stanchions, would have carried 31,000 person-trips per day. In the build
alternative, the light rail system was projected to serve 17,400
person-trips per day, for a net loss of capacity of 13,000 person-trips per
day.
These findings were confirmed in another way by the traffic analysis which
found that the light rail system would actually make traffic congestion
worse at the 100 or so intersections and links for which congestion effects
were calculated.
