UTDrive Corpus Classical


The vehicle used in data collection is a TOYOTA RAV4 customized with a variety of input channels for multi-modal data acquisition on cruise. Recorded data include audio (microphone array and close-talk microphone, six channels in total), video, pedal pressures, following distance, CAN-Bus information and GPS information. From these channels audio and video are very rich in information content and this can be reached by further analysis such as stress level measurement in speech signal and driver's eye and head movements for gaze analysis. Data can be interpreted at multi-levels and can be fused with different combinations of signals to open new areas in inter-disciplinary driver behaviour analysis research and to bring deeper understandings in driver behavior, resulting in new in-vehicle technologies. The corpus includes 37 female, 40 male drivers data at the moment.

UTDrive Corpus Portable


In addition to the classical data collection approach with expensive equipment, the use of smart portable devices in vehicles creates the possibility to record useful data and helps develop a better understanding of driving behavior. Smartphones contain a variety of useful sensors such as cameras, microphones, accelerometer, gyroscope, and GPS, which could potentially be leveraged as a cost effective approach for in-vehicle data collection, monitoring, and added safety options/feedback strategies. Moreover, these multi-channel signals would also be synchronized together, providing a comprehensive description of driving scenarios. Portable mobile platforms lower the entry barrier and allow for a wider range of naturalistic data collection opportunities for vehicles and driver's operating their own vehicles.
