Real-Driving Emissions Dataset for a Mixed-Powertrain Vehicle Fleet

This dataset contains real-driving emissions data from three vehicles in the University of Alberta fleet: a 2015 Toyota Prius with a hybrid electric powertrain, a 2021 Ford Escape with a plug-in hybrid electric powertrain, and a 2019 Ford Expedition with a conventional turbocharged gasoline powertrain. The vehicles were driven a total of approximately 180 km in Edmonton, Alberta, under various driving conditions, including urban and highway routes, across a temperature range of -15°C to 23°C. Data collection was performed using the Global MRV Axion portable emission measurement system, with a sampling frequency of 1 Hz. The dataset includes cold-start phases and provides emissions data for CO₂, CO, NO, and UHC, along with additional vehicle operating parameters obtained via on-board diagnostics (OBD).
