guidelines for the design of
pedestrian and transit streets
Develop as part of an overall central area plan
Obtain positive support from business and civic interests
Coordinate with ongoing development and transportation
actions
Connect major

such as department stores and office
buildings
Provide an adequate supply of conveniently located and
readily accessible off-street parking (shopper parking should be
located in the same or adjacent block to the mall; ideally within
400 feet, except in larger cities). Parking supply and price
should complement, rather than compete, with transit; they will
depend on the intensity of the city center and its reliance on
public transportation
Provide convenient transit service. Buses and rail vehicles
may operate directly on the mall where routing patterns and
physical conditions permit
Develop suitable routes for vehicles currently using the street
to be pedestrianized. Parallel one-way streets with suitable
transition at each end of a pedestrian street provide one such
solution
Enable pedestrians to walk from one side of the street to
another with little or no interference from vehicles
Provide goods and service vehicle access from parallel streets,
alleys, or cross streets. Where this is not practical, trucks can
use mall before noon
Design mall to accommodate police,
re, and other emergency
vehicles and to allow ef
cient maintenance of public utilities

Suitable parallel access streets are needed to accommodate the displaced traf
c.
Their capacities should be adequate to avoid congestion. Sometimes one-way
couplets are provided on adjacent streets
Public transport service should be provided along parallel streets
Suitable transition of displaced traf
c to parallel streets is essential to avoid
congestion
Landscaping, chairs, benches, tables, fountains, and other amenities should be
provided along traf
c-free pedestrian streets
20.3 Road Space Rationing
Road space rationing is a travel demand strategy that attempts to reduce the traf
c
congestion and the negative externalities generated by travel demands that con-
stantly exceed the available capacity. It is achieved by restricting access into the
