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...

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...

Webinar: Integrating explicit and implicit methods in travel behavior research

Car crashes are still a leading cause of death in the United States, with vulnerable road users like bicyclists and pedestrians being injured or killed at rates that outpace their mode share.

Planners, engineers, and advocates are increasingly adopting Vision Zero and Tactical Urbanism approaches and trying to better understand the underlying causes...

Abstract: Walking and bicycling are being promoted as transportation options that can increase the livability and sustainability of communities, but the automobile remains the dominant mode of transportation in all United States metropolitan regions. In order to change travel behavior, researchers and practitioners need a greater understanding of the mode choice decision process, especially for walking and bicycling.

This presentation will summarize dissertation research on factors associated with walking and bicycling for routine travel purposes, such as shopping. More than 1,000 retail pharmacy store customers were surveyed in 20 San Francisco Bay Area shopping districts in fall 2009, and 26 follow-up interviews were conducted in spring and summer 2010. Mixed logit models showed that walking was associated with shorter travel distances, higher population densities, more street tree canopy coverage, and greater enjoyment of walking. Bicycling was associated with shorter travel distances, more bicycle facilities, more bicycle parking, and greater enjoyment of bicycling. Respondents were more likely to drive when they perceived a high risk of crime, but automobile use was discouraged by higher employment densities, smaller parking lots,...

PRESENTATION ARCHIVE

Active travel such as walking and bicycling can lead to health benefits through an increase in physical activity. At the same time, more active travelers breath more and so can experience high pollution inhalation rates during travel. This webinar will review the state of knowledge about how roadway and traffic characteristics impact air pollution risks for bicyclists, including the latest PSU research quantifying bicyclists' uptake of traffic-related air pollution using on-road measurements in Portland. The PSU research team including Alex Bigazzi, Jim Pankow, and Miguel Figliozzi quantified bicyclist exposure concentrations on different types of roadways, respiration responses to exertion level, and changes in blood concentrations of pollutants. Implications for planners, engineers, and policy-makers will be discussed, including guidance for more pollution-conscious bicycle network planning and design. Additionally, ways for individual travelers to reduce their air pollution risks will be discussed.

This 60-minute webinar is eligible for one hour of training which equals 1 CM or 1 PDH. NITC applies to the AICP for Certification Maintenance credit for each webinar. We will provide an attendance certificate...

Putting the Fun Before the Wonk: Using Bike Fun to Diversify Bike Ridership

The Community Cycling Center has been at the business of broadening access to bicycling for 22 years. Far before anyone was talking about "equity" in the world of bike commuting and advocacy, the Community Cycling Center was working directly with youth of color to make...

Summary: In this seminar, Tara Weidner will discuss changes in the works to the State Analysis Procedures Manual (APM) to include three graduated levels of bike planning methods for use in Oregon communities, based on community size, data needs, and planning stage.  These include the Bike Level of Traffic Stress (BLTS), a sketch tool used to assess bike network connectivity, the data-heavy Highway Capacity Manual Multi-modal Level of Service (MMLOS) procedures, and a simplified MMLOS developed by the same researchers. 

Bio: Tara Weidner is an Integrated Transportation Analysis Engineer in ODOT’s Transportation Planning Analysis Unit (TPAU).  She has over 20 years of experience in modeling and analysis of multi-modal transportation systems. Her work focuses on arming Oregon’s communities with tools to plan for the future, including being the lead on ODOT’s GreenSTEP Greenhouse Gas model and coordinating other multi-modal transportation and land use tools and analysis. She joined TPAU about a year ago after working as a Senior Planner for Parsons Brinkerhoff (PB), where she was the consultant lead for the ODOT StateWide Integrated Model (SWIM) and worked with the FHWA on Mega-Regions modeling tools and managed a webinar series on "Climate Change Planning for MPOs.
