Generalized Adaptation of an Electric-Hydraulic hybrid drive system

James Long
Steve Edgeman , Xin Wang
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 ga... Read More

Evaluating the Distributional Effects of Regional Transportation Plans and Projects

Kristine Williams

Metropolitan planning organizations (MPOs) have long been required to consider the equity implications of their regional transportation plans and processes. Funded by the National Institute for Transportation and Communities, this research aims to provide additional guidance to MPOs on how to evaluate distributional equity in regional plans and projects. The report begins with an overview of federal requirements related to equity in transportation planning. We then synthesize contemporary met... Read More
