Types of Operation
The following excerpt was taken from the1992 edition of the Traffic
Engineering Handbook, published by the Institute of Transportation Engineers (pp.
204-205).
Most of the so-called public parking facilities represent a more centralized and
general-purpose use. Parkers usually have a choice of several destinations. Much of the
time they also have a choice of alternate places to park. A facility open to the general
public usually needs to attract parkers if investment in its construction is to be
justified. When the facility is revenue-financed, the need is obvious. Even when the
parking is free, justification is needed for the expenditure of benefit district
assessment funds, parking meter revenue, or other public funds used to acquire land and to
construct and operate the facility.
The design of a general-purpose parking facility must take into consideration the type
of proposed operation with attendants, by self parking, or with a combination of
the two. The most economical operation occurs where patrons park their own cars. In
heavily used facilities where patrons pay for parking, it is sometimes feasible to utilize
attendants to park the cars after the patron pulls into the lot. This also frequently
occurs in older parking garages. Some facilities can operate on both systems, with certain
areas reserved for self-parkers and other areas served by attendants. . . .
A basic factor in design of a parking facility is the expected use by type of parker or
type of generator being served. Parking duration can be either short-term or long term, or
a combination of both. Design dimensions are often larger in facilities for short-term
parkers because of the high turnover rate and the need to provide easy access and
circulation. . . .
