We want to meet you!

“Filling potholes doesn’t ‘fix’ our transportation system, but simply paves over a system of highways designed for a 20th century California,” said Jeanie Ward-Waller, policy director of the California Bicycle Coalition, in a September 1 op ed piece in The Sacramento Bee. As transportation systems all across America transition from the concrete paved, car-oriented culture of the past, you are part of this exciting transformation! Join fellow Landscape Architecture and Transportation Professional Practice Network (LAT PPN) members in discussions of current issues at the ASLA Annual Meeting and EXPO in Chicago this November.

Show us who you are! We invite you to participate: 

  1. Send us a proposal for a short talk about an issue concerning you for the Landscape Architecture and Transportation PPN meeting. Presentations can be about anything related to transportation, from complete streets and multi-modal transportation planning to green streets, erosion control, and ecological restoration. Submit a title, short summary paragraph, and brief outline for your slides (one to two words per slide) to Ellen Barth Alster at Proposals are due by October 1, 2015.
  2. Send us 1-3 images about yourself and the work you do. Everyone attending the Annual Meeting has a voice that should be heard and we want to know more about you, our fellow PPN members. The images can be about anything: your favorite place, your daily commute, or your most frustrating transportation design challenge. Please send images (as JPEG files) by October 30, 2015 to the LAT PPN leadership team.

The Landscape Architecture and Transportation PPN meeting will take place on Saturday, November 7 at 9:15 AM. We look forward to seeing you in Chicago!

We welcome all questions and comments. Please contact Ellen Barth Alster (, LAT PPN Co-Chair, or Davie Biagi (, LAT PPN Officer.

Transit Deserts: Failing to Provide Access

The story of Detroit resident James Robertson, who, due to patchy bus service, walked 21 miles as part of his daily commute to get to a factory job 23 miles away in the suburbs where he earned $10.55 an hour, captured the public imagination in February 2015 when his story was publicized. It generated a crowdsourcing response of over $350,000, and a local Ford dealer’s donation of an automobile. While the outpouring of generosity solved one man’s transportation issues, it failed to provide for the rest of the fragmented Detroit metropolitan region, or other regions facing similar issues, crippled by suburbs that intentionally choose to opt out of regional bus service. While Baltimore is comparably better served by public transit than other metropolitan regions, its African American residents have provided their own highly effective, yet illegal, answer to transit deficiencies: hacking. Diane Jones Allen, ASLA, discusses these issues and offers a response in her dissertation for Morgan State University in 2014. She is currently furthering this topic in a book about transit deserts, race, and suburban form. Portions of her dissertation and future book are summarized and excerpted below.
–Ellen Barth Alster, ASLA, Landscape Architecture and Transportation PPN Chair

Within the past five decades, public transit-dependent and urban-oriented populations have been relocated or shifted to outer-urban, auto-oriented neighborhoods at the same rates that African-Americans moved to northern cities from southern rural communities during the preceding five decades of the Great Migration. These outer-urban areas have not offered adequate public transit to support economically viable employment, nor have they provided access to social and cultural networks, resulting from the suburban and low density built forms which favor the automobile. These areas are called “Transit Deserts,” a term first used in 2007 by Professor David Hulchanski from the University of Toronto. This topic is closely related to the “Food Desert” discourse, tying geographic form, neighborhood income, and public and private policies into a triangular model that drives an ever increasing number of American citizens into poverty through a narrowing of access to quality food or transportation.

Stormwater Infrastructure & Streetscapes

The article below, written by Professional Engineer Nathan Polanski of SvR Design Company, is based on a presentation Nathan gave to the Landscape and Environmental Design Committee of the Transportation Research Board at that organization’s Annual Meeting in Washington, DC this January.

Integrating Green Stormwater Infrastructure into the Streetscape

Across the country, local governments are integrating green stormwater infrastructure (GSI) into the streetscape to manage urban stormwater runoff. More frequently implemented to reduce combined sewer overflows (CSOs), streetside GSI also treats polluted runoff that includes oil, heavy metals, and carcinogens to help protect the quality of local water bodies. Often overlooked, however, is the vital role that GSI can play in creating a thriving, pedestrian-friendly streetscape by providing physical buffers, reducing imperviousness, increasing opportunities for tree canopy, mitigating heat island effect, and promoting traffic calming.

Bike Maps

Luckily I have had the pleasure of living in a few cities that find bicycle commuting important and recognize the best way to get people out of their cars and onto a bicycle is to make that step a bit less frightening.  Chicago, Pittsburgh, and Washington DC are just a few cities that have taken steps to add bike lanes to their streets and provide maps of these bicycle-friendly streets to residents and visitors.

Usually these map legends point out bike trails, on-street bike lanes, and streets that are recommended for bicycling without marked lanes.  Though helpful for the seasoned bicycle commuter, a first timer may not be ready to venture out just yet.

The city of Austin is taking this to the next step and has developed a mapping system that “prioritizes rider comfort in its symbology.”  The color-coded bike network is “keyed to the real-world experience a person can expect when cycling on any given street.”

Bicycling in Spain: Is there a relation to Land Use?

This article could easily be written by a member of the International or Transportation PPNs, but the bicycle is becoming increasingly important in Land Use, so it is offered here to spark a discussion about the importance of alternate transportation in community design.

Living in Aspen, Colorado, cycling has become a part of our lifestyle.  Whether it is mountain or road biking, trails and facilities exist to encourage even the most timid into this healthy recreation.  In town, year-round cyclists, some with studded snow tires, regularly use cycling to get to work and run errands.  So, it seemed natural in planning a trip to Spain (in a country where the famed Vuelta de España race ranks among the top three cycling events worldwide), to see what is happening with respect to cycling.  Our trip therefore included a week of cycling through Andalucia as well as visits to Madrid and Seville, two cities that have gone far to develop car-free pedestrian zones.  But how well do they accommodate cycling as an alternative mode of transportation and means of recreation?  It turns out that these cities could not be more different in this respect, something that no doubt reflects the divergence among U.S. cities as well.  In the countryside, some significant efforts are made for cycling safety on rural roads, and rails-to-trails is part of the program.

Bicycle Connectivity: A New Perspective

Moving Beyond the Network

You could say that the author has some familiarity with the subject of bicycle connectivity; over the course of finishing his MLA degree at the University of Oregon, he pedaled over 6,500 miles in and around the city of Eugene.  The city is already well known for its bicycle friendly environment, but this did not stop the Colorado native from questioning how it can be made even better. His hope is to make cities and communities more hospitable places by creating innovative approaches to bicycle connectivity.  The author’s graduate research explores current thought on the subject then details a new, holistic approach to that goal.

Identity, Streetscapes and Regional Rail in Taipei, Taiwan

In less than 30 years, Taipei, Taiwan has undergone significant transformation in its cultural identity, its urban design, and its regional transportation systems. Taipei, the largest city of Taiwan, lies on the Danshui River 25 kilometers across the Taiwan Strait from China. Taipei City has approximately 2.6 million residents, and the metropolitan region has just shy of 7 million people. While Taipei is not the largest city in the world by any stretch of the imagination, the city is one of the most densely packed, due to the natural hilly topography and limited areas upon which to build city structures.
