Using Mathematical Models To Enable Transportation Decarbonization & Combat Climate Change


Conducted in partnership with the U.S. Agency for International Development, a National Renewable Energy Laboratory (NREL) study assessing the electrification potential of transit fleets in two Mexican cities determined that at least 80% of the operational bus days for the studied routes were suitable for electrification — with a 250-kWh battery in Mexico City and a 300-kWh battery in León.

The evaluation coupled easily accessible GPS speed traces with an electric bus model to identify vehicle requirements. Such simplified evaluations can be duplicated globally to advance energy-efficient mobility options. Transit electrification is a key strategy for ensuring that technologies that reduce greenhouse gas emissions also enable greater access to mobility services.

Researchers detailed their methodology and findings in a conference paper that earned a best paper award at the 2020 IEEE Transportation Electrification Conference.

The paper, “ Transit Bus Electrification Evaluation from GPS Speed Traces ,” was based on data collected in Mexico three […]
