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.

The video begins at 2:13.

Abstract: City of Davis Bicycle and Pedestrian Coordinator Tara Goddard recently visited Sangju, South Korea as part of a "sister city" delegation. Sangju is the "Bike City" of Korea, with a bicycle mode share approximately that of Davis and Portland combined. Tara will share photos and lessons learned from that trip, compare the bicycle facilities of Sangju with that of Davis and Portland, and discuss opportunities for future bicycle research in East Asia.

Webinar: Addressing Bicycle-Vehicle Conflicts with Alternate  Signal Control Strategies on Oct 16, 2018

OVERVIEW

There is nationwide interest in supporting sustainable and active transportation modes such as bicycling and walking due to the many benefits associated with them, including reduced congestion, lower emissions and improved health. Although the number of bicyclists is increasing, safety remains a top concern. In urban areas, a common crash type involving bicycles at intersections is the “right hook” where a right-turning vehicle collides with a through bicyclist. While geometric treatments and pavement markings have been studied, there is a lack of research on signal timing treatments to address right-hook bicycle-vehicle conflicts.

Addressing Bicycle-Vehicle Conflicts with Alternate Signal Control Strategies, published in April 2018, is the first study to explore bicycle signal control strategies for addressing bicycle-vehicle conflicts. This study analyzed the operational impacts of traditional concurrent...

Summary: Urban bicyclists’ uptake of traffic-related air pollution is still not well quantified, due to a lack of direct measurements of uptake and a lack of analysis of the variation in uptake. This paper describes and establishes the feasibility of a novel method for measuring bicyclists’ uptake of volatile organic compounds (VOC) by sampling breath concentrations. Early results from the data set demonstrate the ability of the proposed method to generate findings for transportation analysis, with statistically significant exposure and uptake differences from bicycling on arterial versus bikeway facilities for several traffic-related VOC. These results provide the first empirical evidence that the usage of bikeways (or greenways) by bicyclists within an urban environment can significantly reduce uptake of dangerous traffic-related gas pollutants. Dynamic concentration and respiration data reveal unfavorable correlations from a health impacts perspective, where bicyclists’ respiration and travel time are greater at higher-concentration locations on already high-concentration roadways (arterials).

Bio: Alex Bigazzi is a Ph.D. candidate in Transportation Engineering at PSU, where he is also teaching a class on transportation emissions modeling. His dissertation investigates how urban bicyclists...
