the Portland instruments.

Area of Analysis
Significant Relationships
(Cervero 1989)
Suburban employment centers
Walk/bike and transit shares are greater
where retail uses complement office
uses
(National comparison)
(Cambridge Systematics
1994)
¼ mile radius around work sites
in Los Angeles area
Transit share is greater with substantial
land-use mixing or convenience
services nearby.
Walk/bike share is greater where
substantial land-use mixing or
convenience services nearby.
(Cervero 1991)
Six U.S. Metropolitan areas
Transit share is greater in mixed use and
multi story buildings.
Average vehicle occupancy is higher in
mixed use buildings
(Cervero 1996)
Eleven U.S. Metropolitan areas
Use of transit and walk/bike is more likely
where commercial uses are nearby.
Work trips are shorter where
commercial uses are nearby.
For short trips, mixed uses induce
walk/bike commuting as much as highrise development
(Cervero and Kockelman
1997)
San Francisco Bay Area, CA
VMT for nonwork trips is lower where
intensity factor or amount of vertical
mixing is greater.
(Loutzenheiser 1997)
San Francisco Bay Area, CA
Walking to a transit station is more likely
where retail uses predominate around
transit stations

Abstract:
In response to suburban transportation problems, developers and planners have
suggested that mixing land uses can reduce automobile dependency by making more
goods and services available within walking, biking, and short driving distances. This
view has resulted in a neotraditional planning movement that promotes neighborhoods
designed with traditional characteristics including a mix of land uses. However, few
studies have empirically explored the transportation implications for these neighborhoods.
This issue is addressed by using a travel diary collected in three greater Seattle area
neighborhoods characterized by neotraditional neighborhood elements including mixed
land use. These data were compared with those collected in an identical diary from
individuals throughout the region. It was found that residents of the mixed land use study
neighborhoods in Seattle traveled 28% fewer kilometers (miles) than residents in
adjacent areas and up to 120% fewer kilometers than residents in suburban areas. This
trend of lower travel distances held across different socioeconomic characteristics.
However, the differences in travel distances among the areas were not seen when travel
time was considered. The daily travel time was about 90 min/person (including walking),
regardless of where that person lived and that person's socioeconomic status. One
implication of this finding is that if a neotraditional neighborhood development does make
shopping and other chores less time-consuming, there may simply be more time in the
travel budget for additional regional travel. This suggests that travel from the
neotraditional neighborhoods needs to be examined in a regional context.
