To reduce costs and eliminate air pollution, many cities are exploring the benefits of electric buses. Before electrified fleets take the road, however, officials will require a test run. The National Research Council of Canada (NRC) used a modeling approach.
Instead of large-scale testing on physical buses, the NRC worked with analytical software company Maplesoft to develop system-level models of bus dynamics.
The models allowed the research council to determine optimal locations for charging stations, calculate energy efficiency, and recommend a range of other community-specific factors.
In a presentation this month titled A Modern Electric Bus Fleet: Improving Public Transit with System-Level Modeling, a Tech Briefs reader had the following question for an NRC member:
“This study is for the particular route considered. Will the modeling be extended to different routes? Will each route have a customized bus with results obtained? Or will there be a mean for all routes considered?”
David Holt, Lead Simulation Technician, National Research Council of Canada: This is one route. We run an individual simulation for each route. Generally, we develop a single bus model. We simulated three buses for each of the six provided routes.
In the future, I think the plan is ultimately to have characterized buses. So, a specific 40-foot electric bus, with a certain battery capacity, from a certain manufacturer. We would characterize that specific bus, and apply it to routes as desired by the operators, or our musings as a research facility.
