“
New Riders
”
The study estimated the number of new riders that would be attracted to the
station by adding park-and-ride spaces. An estimate of ordinary ridership growth
was subtracted from the total ridership growth, isolating the number of new riders
then presumed to be attracted to commuter rail by the added parking. The
Bridgeport station experienced a number of other changes during the study period,
including a rail fare reduction, free parking, and a substantial improvement and
cleanup at the station and its environs. The overall ridership increase per space was
0.74 in New Haven, 0.77 in South Norwalk, and 1.47 in Bridgeport. The
“
new
riders
per parking space added were 0.11 in New Haven, 0.60 in South Norwalk,
and 0.92 in Bridgeport.
