Despite widespread use of walking as a transportation mode, walking has received far less attention than the motor vehicle in terms of national guidance and methods to support planning, designing, and operating safe, functional, and comfortable facilities. To address this gap, the TRB National Cooperative Highway Research Program funded NCHRP Project 17-87: Enhancing Pedestrian Volume Estimation and Developing HCM Pedestrian Methodologies for Safe and Sustainable Communities. Led by Principal Investigator Paul Ryus, Kittelson & Associates partnered with Portland State University and the Highway Safety Research Center at the University of North Carolina to lead research to update pedestrian analysis methodologies in the Highway Capacity Manual (HCM). 

The research team created the following new products, published in 2022 and free to download from the National Academies Press:

  • NCHRP Research Report 992: Guide to Pedestrian Analysis: Documents the state-of-the-practice for pedestrian volume counting, pedestrian safety analysis, and pedestrian operations analysis. A major portion of the research evaluated the effects of safety countermeasures at street crossings on pedestrian quality of service (QOS...

A new NITC report examines factors that predict whether a driver will comply with Oregon laws aimed at keeping pedestrians safe.

Miguel Figliozzi of Portland State University, director of the Transportation, Technology & People (TTP) research lab, has done extensive work in Portland, Oregon modeling and analyzing the complex interactions between cars, transit, traffic signal technologies and human roadway users.

The research seeks to provide a better understanding of the tradeoffs between traffic mobility, transit performance and pedestrian access.

The first phase of Figliozzi’s research focused on how two advanced traffic control technologies work together. In this second phase, he zeroes in on pedestrian safety.

The report examines traffic and trajectory factors that explain whether a driver complies with Oregon law, which has strong pedestrian protections. In Oregon, drivers must stop for pedestrians as soon as they move onto the roadway in a crosswalk with the intent to proceed.

Oregon state law determines that there is a crosswalk at every intersection with or without a marked crosswalk. The state also requires that a driver, before crossing a crosswalk, stop and remain stopped for pedestrians until the pedestrians...

Flashing-yellow-arrow traffic signals offer convenience for drivers by permitting them to turn left after yielding to oncoming traffic. This convenience, OTREC research has found, can come at the expense of safety, especially where the traffic mix includes pedestrians.

OTREC researchers David Hurwitz of Oregon State University and Christopher Monsere of Portland State University examined how driver behaviors affect pedestrian safety at flashing yellow arrows. Their findings show that drivers at these intersections often don’t even look for pedestrians.

This research will be the focus of OTREC’s first live interview-style Webinar May 7. Host Steph Routh of Oregon Walks will interview the researcher-practitioner team, explore real-world applications and take audience questions. The Webinar is free. Details are at this link:

Flashing-yellow-arrow Webinar

Flashing yellow arrows have been replacing other left-turn signals, such as solid green or flashing yellow or red circles, to indicate that drivers may turn after yielding to oncoming traffic. These turns are considered “permissive.” Turns where no conflicting traffic is present, such as those indicated with a green arrow, are “protected” turns. The flashing yellow arrow’s inclusion in the 2009 Manual on Uniform Traffic Control Devices sped up the signal’s adoption to...

THE TOPIC

Past research and planning has highlighted the existence of pedestrian injury disparities throughout the US and some local agencies have performed cursory analysis in Oregon. However, no statewide analysis of pedestrian injuries in Oregon has been completed to see how these injury outcomes differ by race and income.

This presentation aims to help better understand the factors...
