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

Improving pedestrian safety continues to be critically important to ODOT’s mission to provide a safe and reliable multimodal transportation system. Approximately 920 pedestrians were injured, and 78 pedestrians were killed in Oregon each year between 2016 and 2020. Some of these pedestrian-vehicle… Read More

Shared micromobility (including shared electric scooters and bikes provided by private companies) is one of the newest transportation options that has come to cities in the last several decades. A new report explores the different ways cities charge shared micromobility companies to operate, and… Read More

The primary goal of this initiative is to provide the agency with a comprehensive understanding of medium-duty truck operation, identification of potential areas of risk, forecast of future operational growth and monetization of the costs associated with these changes. To meet this goal, the… Read More

Crash prediction analysis focuses on identifying attributes that result in traffic crashes and proposes effective countermeasures to improve the roadway design and operational attributes. These crash frequency models are typically employed for examining crash counts either at the micro-… Read More

Portland State University has conducted a North American survey of e-bike owners. The primary objective of this study is to gain a better understanding of the factors that influence purchase and use of e-bikes from existing users. Understanding who uses e-bikes, how they are used and the potential… Read More

The city of Portland has developed a national reputation as a bike-friendly city as a result of numerous citywide bike infrastructure plans, yet as is true across the country, ridership data indicates that people of color make up a small portion of regular cyclists. The current study draws from 25… Read More

BACKGROUND One of the most common locations for fatal motor vehicle-bicyclist crashes is at intersections, which inherently have a large number of turning conflicts. Reducing these conflicts is a key objective in improving intersection safety across all modes. Of particular concern for… Read More
