Research Highlights

Agent-Based Model Simulating Pedestrian Behavioral Response to Environmental Structural Changes

Amy Lobben Christopher Bone
Our research focused on understanding the travel behavior of individuals in complex urban environments. Specifically, we investigated how land use patterns and infrastructure influence how individuals across a broad range of travel abilities navigate through urban landscapes. Our overall project goal was to develop a transportation planning tool that allows users to simulate pedestrian travel behavior. The tool was built on a computation model that was developed through rigorous measures and… Read More

Establishing Risk-based Bridge Management Models and Tools for Municipal Transportation Assets

David Yang
The Portland Bureau of Transportation (PBOT) manages a bridge inventory including National Bridge Inventory (NBI) bridges, non-NBI pedestrian bridges, and culverts. Historically, condition data has been stored in disparate and/or non-digital formats, hindering efficient management and decision-making for rehabilitation efforts. PBOT is addressing this by migrating to AASHTOWare BrM, a bridge management system, to digitize and standardize infrastructure data. However, this process faces… Read More
