“City Greenways” is a concept proposed as a part of Portland’s 2035 Comprehensive Plan, which calls for a citywide network of park-like pedestrian and bicycle friendly streets crisscrossing the city at roughly three-mile intervals. This research establishes several approaches to measure the transportation network impact of the “City Greenways” and relate bicycle network measures to economic and social equity outcomes. Expanding upon existing literature, we derived three sets of bicycle… Read More

KersTech Vehicle Systems is in the process of creating a hybrid drive system combining a flat format hydraulic motor with an electric motor for energy recapture of vehicle momentum. The initial drive system is targeted at a specific vehicle application. A main component of the drive system being developed is a controller and the associated algorithm. The controller algorithm is a new adaptation of an optimally robust algorithm for model uncertainties and resilience against control feedback gain… Read More
