Activity-travel behaviour analysis for universal mobility design

This special issue provides additional insights into activity-travel behaviour analysis for universal mobility design. Four papers are included, focusing on behavioural issues of elderly who need nursing care, children and parents, low-income persons and car-deficient households. Time use, travel mode usage, car allocation within households and activity scheduling behaviours are analysed in these papers, using large-scale samples. Promising methods about the representation of inter-personal interactions and diverse behavioural variations as well as empirical findings are provided. Methodological challenges and mobility policies in the future are also discussed.
