Abstract: The bike movement in the United States tends to support infrastructural changes to streets. Reshaping the built environment is expected to stimulate behavior changes in road users. At the same time, this approach may overlook the transportation cultures of existing urban communities and raise concerns about displacement and gentrification. Based on ethnographic research and advocacy experiments in Los Angeles, Lugo proposes the concept of "human infrastructure" to describe the ways that social relationships impact how people experience the built environment. By taking both physical and human infrastructure into account, transportation planners and advocates can make social justice a key part of sustainability.

This seminar will present results from the BikeGPS study that collected data from Portland area bicyclists using GPS technology. The study collected data from over 150 cyclists for seven days each during 2007, resulting in detailed information for over 1,500 bicycle trips throughout the urban area. The GPS data provides detailed information on the amount, location, and speed of bicycle travel and allows us to answer questions about route choice. For example, how much to people ride on roads with bike lanes, on bike boulevards, or paths? Do these patterns vary by gender, age, or other factors?

Ronald Tamse is a traffic engineer for the city of Utrecht, The Netherlands. Ronald has been involved in traffic design in Amsterdam and Utrecht. He is most interested in bicycle and rail transportation. He has worked on the design of the Amsterdam subway, a light rail system in Utrecht, and is currently working on urban transportation solutions as Utrecht Centraal is redeveloped. Utrecht Centraal is the largest train station in The Netherlands.

Ronald will highlight key examples from Utrecht that show some new ideas, similarities between the Dutch and American approaches, as well as a few lessons imported from Portland. These examples will share highlights from major projects that include building a new commuter railway network, including the rebuilding of Utrecht Centraal railway station, and the development of a light rail line in Utrecht that uses MAX as a development model. In addition, Ronald will demonstrate the importance of connecting bike infrastructure through network planning, infrastructure, and connections to transit.

Topic: Trick or Treatment? Impact of Route-Level Features on Decisions to Walk or Bike
Summary: Some travel routes attract people walking and cycling, while others may scare them away. What features of street environments are most important, and how do available routes affect decisions to bike or walk on a specific trip? 

Research to date has focused on either large-scale areal measures like "miles of bike lane nearby" or else has considered only shortest path routes. Neither method is suited to capturing the impact of targeted route-level policies like neighborhood greenways. This session will present a new technique for measuring bike and walk accessibility along the most likely route for a given trip. The method is applied to travel data, and results provide new insight into the relationship between route quality and travel mode choice.

Abstract: Using the Seattle Bicycle Master Plan as a model, this presentation will provide a roadmap for developing and implementing bicycle master plans.

Toole Design Group (TDG) served as the prime consultant for the City of Seattle Bicycle Master Plan. In partnership with the City, TDG took a diverse approach to public involvement, including working with a Citizen’s Advisory Committee and local advocacy groups, conducting an online survey, and conduction highly successful public input meetings that were attended by hundreds of people. The project involved extensive GIS and field analysis, and the development of specific recommendations for street reconfigurations and wayfinding signs for a 450-mile network of on and off-street facilities. The project included design innovations such as shared-lane markings, up-hill bike lanes, buffered bike lanes, and new warning and wayfinding signs. It also included new thinking on right-of-way assignment and the design of trail street crossings. In addition, TDG developed bicycle facility design guidelines recommendations for education and enforcement programs to support and encourage bicycling, and policies for integrating bicycle considerations into all City projects and programs. The Plan focused heavily on implementation and included...

During the March 2011 earthquake/ tsunami/nuclear disaster, the internet filled with stories of how something quite ordinary in Japanese life became an important lifeline—the bicycle. For example an 83-year-old woman escaped the tsunami by bicycle, and due to public-transport disruptions, bicycle stores sold out of bicycles as quickly as supermarkets sold out of food. However not just in disasters, but in daily life, the most reliable, sustainable form of transportation, next to walking, is via Japan’s estimated 80,000,000 bicycles, affectionately called mamachari.

This illustrated presentation, based on four-years of cultural-landscape research culminating the publication of世界が称賛した日本の町の秘密 (Secrets of Japanese Cities the World Admires. Tokyo: Yousensha, 2011), begins by discussing why mamachari are perfect for local transportation and the many practical ways Japanese use them. It then explores why many of Japan’s densely populated, fine-grained neighborhoods with auto-resistant narrow streets and nearby shopping, make ideal bicycle neighborhoods. Issues explored will include the mamachari’s impact on: neighborhood livability; sustainability; public health through active transportation; fostering direct human contact not possible with motor-car travel; and maintaining the compact human scale of communities by limiting transport of daily...

Summary: The most recent edition of the Highway Capacity Manual (HCM) contains analysis procedures for measuring the level-of-service (LOS), also referred to as quality of service, provided by an urban roadway to bicyclists. The method uses different design and operating features of the roadway segment (e.g. width, motor vehicle volumes and speeds) to assess an LOS grade of A (best) to F (worst). These procedures are used by planners and engineers to recommend how existing streets could be retrofitted or new streets designed to better serve people on bicycles (and other modes). However, the current HCM does not include methods that address protected bike lanes (aka “cycle tracks” or “separated bike lanes”), only conventional striped bike lanes, shoulders, and shared streets. There are other methods for predicting comfort from a bicyclist’s perspective that do consider protected bike lanes, but they are either based only on expert opinion or on surveys in Denmark.

This presentation will describe how to evaluate the level-of-service of a protected bike lane using results from surveys conducted in the United States. The model developed by this project could be used to supplement the current HCM to objectively consider a wider range...

Abstract: Findings will be presented on an evaluation of two innovative bicycle facilities installed in late summer and early fall 2009 in downtown Portland aimed at providing a more separated and comfortable experience for cyclists. The SW Broadway cycle track (near PSU) and the couplet of buffered bike lanes on SW Stark and SW Oak were evaluated to understand how they are functioning on multiple levels. Each facility involved removing a motor vehicle lane by restriping to provide additional roadway space to bicyclists. The facilities were evaluated after they had been in place for approximately one year. Data collected to support this evaluation consisted of surveys of multiple user groups for each facility type, and video data collected by the City of Portland Bureau of Transportation at intersections along each of the routes to understand the facilities' impact on traffic flow, operations and user interactions.
