<br />Implementing Shared Parking
<br />A number of factors must Ix: cunside:red in ostler
<br />to insure efficient design, operation, and ntnnagr-
<br />ment of'shared parking facilities.'1'l,e rescare•h also
<br />cx;uuincd these factors in detail and identified
<br />guidelines for implementing shared parking as fol-
<br />lows:
<br />• Each parking space should be usable I»• all
<br />parkers, i.e., no resu•ir.ticnts.
<br />• The facility t~'ill have significant inbotutcl anti uttt-
<br />I>ennul u~aftic flow at Otte or more pct•ic><Is of the
<br />clay, 'Therefore, the design of the are•ess and cir-
<br />culation system must acconunodate hi-directional

<br />circulation concept should he easy to usr anti un-
<br />derstand in order to minimise couFusion ;tad inef-
<br />ficient driving maneuvers.
<br />• -l~he facility would tend to operate `?-1 hours, seven
<br />clays per tc•eek. 'T'hus, safe d;ty anti night operation
<br />wcntld be a significant characteristie•.
<br />• Because of the multiple land uses that ~eould he
<br />served, involving a Variety oP types of parkers (e.g.,
<br />business, daily yet;5us infrequent, shoppers, visi-
<br />tors, recreational. etc.), the facility t~ ill he more
<br />sensitive w effective signing, markings, and other
<br />communication systems.
<br />• "Thought needs to he given to enforrentent of
<br />parking for on-site Visits, since the fae•ility will be
<br />more sensitive to encroachment (i.e., less t~ pic•ally
<br />Vacant space).
<br />• A strategy for the use of the facilin• needs to he de-
<br />veloped in order to guide parkers to the most op-
<br />timum space. •f~he strategy ~~'ould consider:
<br />a. Achieving nutxinntm separation of those
<br />parkers who tend to compete for space, i.e..
<br />being present at the same time (e.g.. shoppers
<br />and cinema patrons attending matinees).
<br />b. Achieving minimum walking distance to those
<br />land uses having captive market relationships.
<br />c. Achieving minimum separation of those parkers
<br />trot competintT for space.
<br />• The data collected in the survey was suE'ficiently
<br />consistent to indicate that a quantitative basis for
<br />estimating shared parking= demand does exist.
<br />Since the shared parking methodology estimates
<br />potential parking requirements for specific mixed-
<br />use or multiuse developments, it can be used as
<br />evidence for a zoning procedure and as a develop-
<br />ment design tool Use in zoning procedures is sig-
<br />nificant because of the parking standards currently
<br />used in most tn~ban areas. fn many cases, the
<br />shared parking anal~•sis will indicate lower parking
<br />requirements. ^
