In-vehicle environment data from a naturalistic driving study conducted in South China

The in-vehicle environment data were collected in a naturalistic driving study conducted in South China. Ten participants drove their own vehicles for one to two weeks. The participating vehicles comprised commonly used EV models in China. The dataset consisting of 1-minute–resolution records contains: vehicle ID; timestamps; vehicle model and type; numbering of each trip; in-vehicle environmental data (seven-point air temperature and single-point CO₂ concentration); number and seating positions of occupants; window and door status; GPS coordinates and vehicle velocity; and exterior weather information (solar radiation, ambient temperature, wind speed, etc.).2026 TRB Annual Meeting: Characterizing In-Cabin Environment Using Naturalistic Driving Data in South China
