The "PercepTrans Data" database comprises raw sensor data collected from smartphones and inertial measurement units (IMUs) during 113 transportation trips in Johannesburg and Durban, South Africa. This dataset aims to characterize the movement of vehicles across various transportation modes (car, minibus taxis, bus, ride hailing services). Passengers carrying the sensors had restricted movement, effectively linking the sensor data to the vehicle's motion. The data is intended for analysis of vehicle movement, including assessing driving quality and identifying mismatches between perceived and actual driving performance.
