This thesis examined older drivers’ mobility and behaviour through comprehensive measurements of driver-vehicle-environment interaction and investigated the associations between driving behaviour and cognitive functions. Data were collected and analysed for 50 older drivers using eye tracking, GNSS tracking, and GIS. Results showed that poor selective attention, spatial ability and executive function in older drivers adversely affect lane keeping, visual search and coordination. Visual-motor coordination measure is sensitive and effective for driving assessment in older drivers.

A psycho-Geoinformatics approach for investigating older adults’ driving behaviours and underlying cognitive mechanismsSun, Q.; Xia, Jianhong (Cecilia); Foster, J.; Falkmer, Torbjorn; Lee, Hoe (2018)Introduction: Safe driving constantly challenges the driver’s ability to respond to the dynamic traffic scene under space and time constraints. It is of particular importance for older drivers to perform sufficient visual ...

Towards unpacking older drivers' visual-motor coordination: A gaze-based integrated driving assessmentSun, Qian (Chayn); Xia, Jianhong (Cecilia); He, J.; Foster, Jonathan; Falkmer, Torbjorn; Lee, Hoe (2018)Visual information for a driver is predominant during driving. Linking drivers' visual search patterns with motor behaviour helps understand how drivers perceived spatial and hazardous information to regulate their physical ...
