7.0 PROPOSED PARK AND RIDE FACILITIES
7.1 PARK & RIDE SITE AND DESIGN CRITERIA
Experience with Park & Ride (P&R) sites nationwide has led to the development of criteria
for their siting and design. A leading industry source for these criteria is the Guide for Park
and Ride Facilities (November, 2004), published by the American Association of State
Highway and Transportation Officials (AASHTO). The most relevant criteria for sites within
the SR-160 corridor study area are those for location and configuration as listed below.
7.1.1 Location
The following criteria help determine the proper siting of Park & Ride facilities.
Wherever possible, site Park & Ride lots on the inbound side of the arterial on which
they are located. This preference results from most users perceiving inbound access
efficiency to be more critical than outbound and they generally time their arrival at a
Park & Ride close to the scheduled arrival time of their transit connection.
Select Park & Ride lot locations that minimize automobile access time and serve the
greatest possible population base that would use the site.
Select Site Park & Ride lots that minimize the need to backtrack, i.e., drive away
from the final destination, to get to the lots.
Basic Park & Ride lots require the following footprints (including driveways and bus
bays):
– a lot with 550 parking spaces requires approximately 6 acres
– a lot with 1100 parking spaces requires approximately 11 acres
– a lot with 1900 parking spaces requires approximately 21 acres
Locate Park & Ride lots along primary transit corridors, minimizing the amount of
time a transit vehicle is not traveling in its primary direction.
Arrange Park & Ride lots to minimize the impact on existing traffic patterns.
Locate Park & Ride lots upstream of congestion and choke-points.
Take advantage of freeways or main radial roadways as much as possible.
Where feasible, take advantage of “opportunistic” or “joint-use” lots where parking
facilities are shared with other activities, such as churches, theaters, and shopping
areas.
Ground slopes of up to 5 percent are acceptable for Park & Ride sites.
7.1.2 Configuration
The following criteria help guide Park & Ride facility design.
