22.3.3.2 Rail Transit
Studies of rail transit park-and-ride facilities show an average of 1.1 cars per space,
and 1.2 transit boardings per parked car. Kiss-and-ride (passenger drop-off and
pick-up) can represent 20
40 % of total peak hour transit station arrivals; median
-
driving distances of 3
2 miles for kiss and
ride are common. Occupancies frequently exceed 90 % of facility capacity.

22.3.3.3 Commuter Rail
Commuter rail lines usually rely on automobile access to stations [
13
]. As shown in
Table
22.5
, almost three quarters of all am peak period METRA (a commuter rail
service in the Chicago metropolitan area) rail boarding bound for Chicago is by
automobile
55 % drive-alone, 13 % dropped-off, and 6 % carpool. The parking
space occupancy was approximately 86 %.

22.3.4 Supply and Use
Use of park-and-ride facilities varies by location and line-haul transit access mode.
Usage is generally lowest for express and local bus lines, and highest for rail transit
and commuter rail lines. Most facilities are well used and many are
