Description of Research Project
The primary goal of the project is to provide vehicle emission and fuel consumption data that can be used to calibrate and validate multi-scale energy and emission models that can assess the environmental impact of different transportation alternatives. The outcome of this project will be better tools for evaluating the energy and environmental impacts of alternative traffic and transportation management strategies.
Implementation of Research Outcomes
- Generated and documented more vehicle-emission and fuel consumption data for different vehicle types under different speed and acceleration operation model using the GT-Suite, an advanced engine modeling software tool.
- Validated emission and fuel consumption models for hybrid vehicles using the GT-Suite software.
- Developed optimized rule-based energy management system for hybrid electric vehicles.
- Used vehicle-emission and fuel consumption data for different vehicle types under different speed and acceleration operation, generated using the GT-Suite advanced engine modeling software, to calibrate fuel consumption and emission models in two microscopic simulation models: VISSIM and Integration and one macroscopic model Transyt 7-F.
Impacts and Benefits of the Project
Education:
- One Ph.D. student in Mechanical Engineering graduated
- One undergraduate electrical engineering student continued working as undergraduate research intern
Research
