David Hensle brings deep expertise in activity-based travel demand modeling and software development. At RSG, he designs and implements high-quality software solutions that help public agencies build durable, transparent, and maintainable modeling systems. With a background in physics and programming, David plays a key role in advancing open-source frameworks such as ActivitySim, where he leads software innovations and supports a wide range of applications.
David has contributed to projects across the United States and Canada, including modeling system enhancements for the Oregon Department of Transportation, the City of SeaTac, and TransLink in Metro Vancouver. He brings a practical, user-focused approach to model development, helping clients answer complex transportation planning questions and clearly communicate modeling concepts and implications.
Outside of work, David is based in the Pacific Northwest and enjoys playing ultimate frisbee and pick-up basketball. During the winter months, he can often be found skiing with his family and watching Gonzaga basketball games.
