In order to make sure bicyclists' needs are considered when improving a transportation system, planners and engineers need to know how many people are biking, and where. 

Traditional bicycle counters can provide data for limited sections of the bike network; often these counters are installed at important locations like trails or bridges. While limited in location, they count everyone who bikes by. Meanwhile, GPS & mobile data cover the entire transportation network, but that data only represents those travelers who are using smartphones or GPS. Combining the traditional location-based data sources with this new, crowdsourced data could offer better accuracy than any could provide alone. 

"Knowing how many people are bicycling on a street is really important for a number of reasons. As just a few examples, bicycle volumes give you a way to understand safety data and determine crash rates. They provide insight into where and how bicycle trips are…

Researchers at Portland State University and Oregon State University have updated the Oregon Department of Transportation (ODOT) Safety Investigation Manual, materials and training resources to assist ODOT traffic investigators with highway safety project investigation, analysis, evaluation, and documentation.

David Hurwitz of OSU worked with Chris Monsere, Sirisha Kothuri and Jason Anderson of PSU to update the manual. The team revised and expanded worksheets used in the safety analysis process and prepared training materials in the form of videos, slide decks, and case study examples to help train ODOT employees and employees from transportation agencies around the state on current best practices.

A decade ago, the first edition of the Safety Investigation Manual was also developed by PSU (Chris Monsere) in collaboration with OSU (Karen Dixon). ODOT continues to look to the leading expe…

Dr. Chris Monsere, PH.D., P.E. of Portland State University has been awarded the 2022 Branford Price Millar Award for Faculty Excellence. The Faculty and Staff Excellence Awards are one example of how the university honors, recognizes, and incentivizes the ongoing excellence of PSU faculty and academic professionals for their research, scholarship, service, and dedication to our students and our academy.

Monsere, who also won the 2020 Outstanding Educator Award from the Western District of the Institute of Transportation Engineers (ITE), is the associate dean for academic affairs in the Maseeh College of Engineering and Computer Science and a professor in the Department of Civil and E…

In 2020, the COVID-19 pandemic drastically impacted travel for in-person shopping, commute trips, global supply chains, and food business operations. E-grocery pickup and delivery services saw unprecedented expansions in response. The adoption and use of these e-grocery services have implications for equity and mobility. A PSU masters thesis offers insights: "Adoption and Use of E-Grocery Shopping in the Context of the COVID-19 Pandemic: Implications for Transport Systems and Beyond" by Gabriella Abou-Zeid, a 2021 graduate of Portland State University with a masters in civil engineering.

"While the future adoption and use of e-grocery services is uncertain as the COVID-19 pandemic evolves, our analysis revealed a clear impact of the pandemic on e-grocery shopping behaviors, which has impacts for transportation network demand, safety, and equity," Abou-Zeid said.
