Knowing how many people use walking and bicycling infrastructure is crucial for transportation planning. Active transportation projects can help cities and states achieve multiple climate- and public-health-related targets, and a new project launching in 2024 can help further those goals:… Read More

While our researchers are experts in various aspects of transportation research, not all researchers have the tools to address equity topics in their research or conduct their work following good equity practices, ranging from data collection and analysis to supporting underrepresented students as… Read More

There is a significant gendered travel behavior research gap in the transportation literature. A plethora of transportation literature identifying and contrasting cisgender disparities exists, but more inclusive approaches to genderdiverse identities remain scarce. The burgeoning field of… Read More

The Affordable Mobility Platform (AMP) is a nationwide community carsharing program providing electric vehicles to affordable housing locations. Forth Mobility (https://forthmobility.org/) is working with local partners including utilities and community-based organizations in eight states… Read More

The number of people experiencing homelessness in the United States has increased in recent years; state transportation rights-of-way (ROWs) are often some of the most accessible areas to set up temporary encampments. This growing trend of encampments on state ROWs has presented unprecedented… Read More

Despite the practical and sustainable mobility benefits of e-bikes, personal ownership and maintenance are considered barriers to adoption (Fitch et al., 2022). Lending e-bikes may address some of the challenges of shared micromobility programs, such as ease of access and payment, but comprehensive… Read More

This study presents a novel approach to bicycle volume estimation using data fusion techniques that integrate crowdsourced data (e.g., Strava) with traditional count data. We aim to improve the accuracy and robustness of bicycle volume estimates in different regions by using deep learning… Read More

Many long-span culverts are subject to loads from heavy trucks, and thus need to be evaluated for their load carrying capacities to estimate safety margins. However, the current manual on bridge evaluation provides limited guidance for bridge-sized culverts due to their distinct structural… Read More

PROBLEM SUMMARY Fatal and severe injury crashes are on the rise in Oregon with one of the prominent factors being excessive speeding. As many cities and communities expand walking and cycling infrastructure there has been an increase in pedestrian fatalities and speeding is a key factor that… Read More

In Spring 2023, the Portland Bureau of Transportation (PBOT) was awarded a Stage-1 grant under the Strengthening Mobility and Revolutionizing Transportation (SMART) Grants Program by the US DOT, titled “Decarbonizing Goods Movement: A Technology-Enabled Zero Emission Delivery Zone.” The City of… Read More

The evaluation of the current ODOT methodology will focus on higher speed roadways such as arterials and roadways with a record of high severity injuries. This will require investigating ways agencies have found to balance between local safety needs and mobility of vehicles on urban arterials and… Read More

Counts provide the foundation for measuring nonmotorized travel along a link or a network and are also useful for monitoring trends, planning new infrastructure, and for conducting safety, health, and economic analyses. For safety analysis, they are critical in assessing the exposure to risk. Over… Read More
