Research Highlights
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...

The new Social-Transportation Analytic Toolbox (STAT) for Transit Networks, developed by NITC researchers in a multi-university collaboration, is a dynamic platform that combines Twitter, general transit feed specification (GTFS), and census transportation planning products (CTPP)—in this case, job density data—to help agencies evaluate overall system performance and identify connectivity gaps. It can also act as a decision support tool for recommending service improvements. The STAT is an o...
