In the past decade bike and pedestrian count programs have sprung up all over the United States, gathering data to evaluate biking and walking infrastructure. However, these modes have not been studied with the quantitative rigor applied to motor vehicle travel. A research project funded by the National Institute for Transportation and Communities (NITC), led by Nathan McNeil of Portland State University (PSU), offers a method for monitoring the quality of this bike-ped count data.

When buses and bikes share space, it's complicated. Not only are there safety risks for cyclists, but also potential delays in bus service and stressful navigation for bus operators. The quest to increase bus speeds—and plausibly...

If Bikes Could Talk: Would Connected Vehicle Tech Get More People Riding?

Sep 26, 2019
John MacArthur, Portland State University

What if your bicycle could warn you that a car is coming from a side street you can't see? Or let you know that your front tire is getting a little low, or that you're approaching a pothole that wasn't there yesterday? A NITC research project led by John MacArthur of Portland State University explores how connected vehicle (CV) technologies could encourage an increase in bicycling. As CV technology moves forward in the rest of the transportation system—with buses and connected streetcars requesting early green lights from the traffic signals, and cars chatting with each other about their locations and trajectories—there may be...

BIKE/PED COUNT SURVEY: CALL FOR INPUT

Researchers at Portland State University, University of Texas at Arlington, University of North Carolina at Chapel Hill and Toole Design Group are conducting a scan to identify locations where bicycle counts are taking place around North America, and hope to enlist your help! If you collect bike count data (or oversee counts) in your jurisdiction, please consider taking our quick survey to tell us a little bit about your count locations and data.

The survey can be accessed here: tinyurl.com/BikeCounterScan

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...

2018 RFP for Two Pooled Fund Projects: Exploring Data Fusion Techniques for Bicycle Volumes & Equity in “Cashless” Transit Fares

Aug 23, 2018

The National Institute for Transportation and Communities (NITC) is soliciting proposals for our two 2018 Pooled Fund projects:

RFP now open; proposals due Oct 1, 2018

This project will address the need of cities and municipalities to combine bicycle data from different sources (such as manual counts, automatic counts, and crowd-sourced data from apps such as Strava) to assess an accurate accounting of bicycle traffic on a network. Current work on data fusion techniques is limited and additional research is needed to fully understand the choice of weighting techniques, inclusion of spatial vs. temporal variation in the weighting scheme and exploring other...

Bicycle Accessibility Measures: Advancing Equitable Economic Benefits through Urban Greenways

Aug 23, 2018
Principal Investigator: Jenny Liu, Portland State University
Learn more about this research by viewing the Executive Summary and the full Final Report, or watching the January 2018 seminar on the Project Overview page.

Portland, Oregon's 2035 Comprehensive Plan calls for “City Greenways” - a citywide network of park-like streets focused on moving pedestrians and bicycles safely. Such a connected network of safe, welcoming active transportation options could have significant benefits for residents—but which residents?

Benefits of bike and pedestrian infrastructure include environmentally sustainable transportation, livability, and improvements in economic development and public health. While these outcomes are well documented, it is also known that both transportation and environmental amenities are typically unevenly distributed in the urban context....
