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...

If American cities are to serve the mainstream population of traffic-intolerant bicyclists, we need a broad range of low-stress facility types that can be applied depending on traffic and space constraints. This seminar will focus on two kinds of bicycle accommodations. A “Bicycle Priority Lane” is a shared lane treatment, like the shared lane arrow or “sharrow” that is becoming popular, intended for streets lacking the space to provide a dedicated bike lane. It enhances the sharrow by providing longitudinal markings that define a “lane within a lane,” drawing from “advisory lanes” (UK) and “suggestion lanes” (NL). We show how defining the bicyclist’s space objectively with road marking frees bicyclists from the stress of negotiating for operating space with motorists.

Separated paths or cycle tracks are bike paths along a road that are physically separated from moving traffic by a curb, median, or parking lane. For decades, they have been the mainstay of bicycle networks in the Netherlands and in Montreal, but have been shunned by US planners due to misplaced safety concerns. We will expose the flaws of the studies used to discredit separated paths, and discuss their safety record in the Netherlands and in Montreal. Practical issues in cycle track design will be discussed based on Montreal’s experience of the last two decades.

The video begins at 1:00.

OVERVIEW

The "Fast Track" project at the University of Oregon focuses on a mode of transportation that is sometimes left out of vehicle-to-infrastructure, or V2I, conversations: Bicycling. NITC researchers developed an app based on a new technology being integrated into modern cars: GLOSA, or Green Light Optimized Speed Advisory. GLOSA allows motorists to set their speed along corridors to maximize their chances of catching a "green wave" so they won't have to stop at red lights.

This project demonstrates how GLOSA can be used by bicyclists in the same way it is used by motorists, with a test site on a busy car and bike corridor feeding the University of Oregon campus: 13th Avenue in Eugene, Oregon. Researchers developed a smartphone app that tells a cyclist whether they should adjust their speed to stay in tune with the signals and catch the next green. The project demonstrates how university researchers, city traffic engineers, and signal-controller manufacturers can come together to help bicyclists be active participants in a smart transportation...
