Identification and Characterization of PM2.5 and VOC Hot Spots on Arterial Corridor by Integrating Probe Vehicle, Traffic, and Land Use Data: The purpose of this study is to explore the use of integrated probe vehicle, traffic and land use data to identify and characterize fine particulate matter (PM2.5) and volatile organic compound (VOC) hot spot locations on urban arterial corridors. An emission hot spot is defined as a fixed location along a corridor in which the mean pollutant concentrations are consistently above the 85th percentile of pollutant concentrations when considering all other locations along the corridor during the same time period. In order to collect data for this study, an electric vehicle was equipped with instruments designed to measure PM2.5 and VOC concentrations. Second-by-second measurements were performed for each pollutant from both the right and left sides of the vehicle. Detailed meteorological, traffic and land use data is also...

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...

As cities move to increase levels of bicycling for transportation, many practitioners and advocates have promoted the use of protected bike lanes (also known as “cycle tracks” or “protected bikeways”) as an important component in providing high-quality urban infrastructure for cyclists. These on-street lanes provide more space and physical separation between the bike lane and motor vehicle lane compared with traditional striped bike lanes. However, few U.S. cities have direct experiences with their design and operations, in part because of the limited design guidance provided in the past. There is limited research from North America on protected bike lanes, but preliminary evidence suggests that they can both improve the level of comfort of cyclists and potentially increase the number of people cycling. This research evaluates protected bike lanes in five distinct contexts varying in population, driving and cycling rates and cultures, and weather: Austin, Texas; Chicago, Illinois; Portland, Oregon; San Francisco, California; and, Washington, District of Columbia. 

These five cities participated in the inaugural “Green Lane Project” (GLP) sponsored by...
