Biking Safely Through the Intersection: Guidance for Protected Bike Lanes
Protected bike lanes are becoming increasingly common around the U.S., yet there is little guidance for extending them through one of their most dangerous links: the intersection. Research suggests that providing comfortable designs is vital to expanding the bicycling population. Studies on cyclists' sense of safety and comfort have generally focused on road segments, rather than intersections. Led by Chris Monsere of PSU in collaboration with Toole Design Group, our latest research report offers guidance for designing intersections that are comfortable for a wide range of cyclists. Watch a video featuring this research, released today from PSU Research & Graduate Studies.
Mobility by E-Bike: Launching a New Study funded by the National Science Foundation and Bosch E-Bike Systems
Do you ride an e-bike with a Bosch onboard computer, and use an iPhone? We're seeking participants from all over the U.S. for a new research project led by John MacArthur of PSU and Chris Cherry of the University of Tennessee, Knoxville. The study will examine the sustainability effects of e-bikes and travel behavior of e-bike users, including origin, destination, route, time, and speed. To gain information about how e-bikes are used for utilitarian transportation, we are looking for e-bike users to passively share their trips with us - just plug in a dongle, download our app, and ride like you normally do.
Analyzing the Functionality of Unprotected Bicycle Lanes
A new article by Kelly Clifton, civil & environmental engineering professor and interim Associate VP of Research at PSU, uses an observational method and coding framework to examine how well unprotected bicycle lanes function as dedicated travel lanes for bicyclists. Specifically, the paper focuses on how people behave and interact on street segments with these facilities in place. This research seeks to provide design and policy recommendations to improve the safety of unprotected bicycle lanes using empirical evidence of road users’ travel behavior, conflicts with other road users, and compliance with traffic regulations.
PSU Transportation Research at TRB 2020
The 99th annual meeting of the Transportation Research Board (TRB) will be held in Washington, D.C. January 12–16, and TREC will be there in force, as is our tradition. Fourteen PSU faculty and twelve PSU students are heading to TRB to present their expertise on this national stage. They be sharing much of the work you've seen released in our monthly newsletter in lecterns, posters, and committees. Download the full PSU schedule at TRB (and other Portland, Oregon partners) and see some of our session highlights below. If you'll be in D.C., don't forget to join us on Monday, January 13 for our NITC reception at Fado Irish Pub!
