7 principles developed to foster smarter transportation networks.

Transportation infrastructure is a significant component of the public
realm, but we can do better than build yet another car-centric
landscape, according to a new guide
on transportation
launched today by the American Society of
Landscape Architects (ASLA).

The ASLA guide provides in-depth solutions and case studies to help
communities create transportation systems that foster safe, equitable
and resilient ways of getting around.

Its sections on regional, urban, neighborhood and street systems reflect
seven key principles:

Low-emission: Sustainable transportation systems don't contribute
to climate change; instead, they encourage low-emission modes of
transportation such as mass transit, biking, or walking. Sustainable
land use practices such as transit oriented development facilitate
multi-modal systems where residents
can easily walk or bike to meet basic daily needs
. Landscape
architects plan regions, cities, and neighborhoods and design streets
that support widespread adoption of low-emission transportation options.

Active: A lifestyle organized around human-powered transportation
choices such as walking and biking is healthy. A
2016 report
found that walkable, transit-oriented communities
increased physical fitness and mental health. Residents of such
communities were also more likely to meet or exceed daily physical
activity recommendations. Landscape architects encourage active
transportation by designing safe, pleasant routes for walking and biking.

Safe: The World Resources Institute estimates that more
than 1 million lives could be saved annually from wider adoption of
traffic calming measures
such as lower speed limits, reduced lane
widths, and protected medians. Landscape architects design for safety
and help cities eliminate serious injuries and fatalities on roadways.

Equitable: Access to such healthy, sustainable transportation
options should be viewed as a right. All residents—regardless of their
income, race, age, disability, religion or national origin—should have
access to affordable, safe, accessible, multi-modal transportation
options that allow them to fully participate in the community. Landscape
architects facilitate community-driven planning, policy making, and
design that includes all members of the community, especially those most
affected by poverty, communities of color, and historically-marginalized
communities.

Resilient: Extreme weather events can easily shut down
transportation networks. Multi-modal transportation systems are
resilient to the uncertainties posed by climate change, such as rising
temperatures, more frequent and intense storms, and sea level rise.
Landscape architects design systems with multiple, interconnected
transportation options that create redundancy and flexibility, qualities
that help
communities evacuate and rebuild quickly in the face of natural disasters
.

Ecological: A sustainable transportation network is ecological,
working with natural systems to capture and filter stormwater, reduce
flooding, support pollinator species, strengthen biodiversity, and
protect wildlife populations. With green infrastructure, wildlife
crossings, pollinator highways, and environmentally-sensitive roadway
alignment, design, and construction, landscape architects integrate
nature into our transportation networks, reaping the benefits
of ecosystem services
while minimizing conflict between humans and
wildlife.

Beautiful: As a major component of our landscape and public
realm, transportation infrastructure should be beautiful, inviting, and
memorable. Thoughtful design creates durable, lasting spaces that forge
community identity, equity, and ownership. Landscape architects ensure
that transportation infrastructure contributes to the aesthetic value of
the built environment.

The sustainable transportation guide was shaped by an expert advisory
panel, including Diane Jones Allen, D. Eng, ASLA, PLA, associate
professor and program director of landscape architecture, University of
Texas, Arlington, and principal, DesignJones LLC; Jean Senechal Biggs,
ASLA, senior project manager, DKS Associates; and Robert Loftis, PLA,
ASLA, associate landscape architect, MRWM Landscape Architects.

This guide is a living resource, so we invite you to submit research,
studies, articles and projects you'd like to see included. Please email

About the American Society of Landscape Architects

Founded in 1899, the American Society of Landscape Architects (ASLA) is
the professional association for landscape architects in the United
States, representing more than 15,000 members. The Society's mission is
to advance landscape architecture through advocacy, communication,
education and fellowship. Sustainability has been part of ASLA's mission
since its founding and is an overarching value that informs all of the
Society's programs and operations. ASLA has been a leader in
demonstrating the benefits of green infrastructure and resilient
development practices through the creation of its own green roof,
co-development of the SITES® Rating System, and the creation of publicly
accessible sustainable design resources.
