The struggle of electric buses
Public transit is a perfect pilot for traffic electrifications while it has its own struggles. Check out the result of this study to investigate existing questions and possible solutions.
Research Cases
Emission modeling
Local emissions are hard to model, because the lack of 1) local drive cycles and 2) local emission measurements. In this study, we explored the emission characteristics of a GDI SUV in the City of Toronto, and built up local emission database through the combination of Toronto specific drive cycles.
How to identify an eco-driver?
How drivers behave is significantly influenced by the surrounding traffic. Even the mildest driver may take aggressive lane-changing behavior in congestion. Therefore, the criteria of eco-driving should be adjustable according to different periods of a day, different road types, and traffic conditions. Click to see how we solve the problem.
Travelers minds are changing, but they inherently follow their rules
Although people value sustainability, their behavioral choice and attitudinal preference may vary in response to different scenarios. Click to check a serie of studies on how people make decisions when facing charging, driving, and traveling suggestions.
Cost-benefit practices for the operation of electric vehicles
In this case, you can dive into details on how the EV energy can be modeled, how to reduce their operation costs, and how to assess their environmental impacts.
Non-exhaust emissions
Non-exhaust emissions can be defined as on-road & off-road wear emissions from vehicles & trains. In this case, both types of NEE are introduced.
Reducing emissions by multi-modal transport
Multi-modal passenger transport offers a convenient & efficient method for inter-city trips. This case illustrates how much GHG, NOx, and PM can be reduced by simply shifting the functionality of remote airports.
