Implementing Oregon’s Energy Plan: Opportunities for Operations and ITS
Jon Makler
Oregon’s 10-Year Energy Plan identifies intelligent transportation systems (ITS) as a key strategy for reducing energy consumption in the transportation sector. Other strategies, including fleet turnover, will take a look time to realize benefits for the state while ITS can be implemented and produce results sooner. This project’s goal was to identify operations/ITS opportunities whose near-term implementation or acceleration can aid the accomplishment of the energy plan’s goals. The research...

Bi-objective Optimization for Battery Electric Bus Deployment Considering Cost and Environmental Equity
Xiaoyue Cathy Liu
Aaron Golub , Ran Wei
Led by Xiaoyue Cathy Liu of the University of Utah, researchers have created a web-based modeling tool that enables U.S. transit providers to explore the impacts of changing over their systems to battery electric buses, or BEBs. The researchers ran the model for TriMet in Portland, OR, as well, with TriMet results and analysis presented in the final report.
“The interactive visualization platform lets users explore various electric bus deployment budget scenarios, so that transit agencies...
