Title: | Tracking household routines using scheduling hypothesis embedded in skeletons | Authors: | HANNES, Els LIU, Feng VANHULSEL, Marlies JANSSENS, Davy BELLEMANS, Tom VANHOOF, Koen WETS, Geert |
Issue Date: | 2012 | Source: | Transportmetrica, 8 (3), p. 225-241 | Abstract: | This study addresses complex daily activity-travel routines of households with young children and their proper representation in a computational process model of travel demand using family skeletons expressed as family sequence patterns. Building on qualitative interview research findings, an a priori classification of family types is defined according to the distribution of care and work responsibilities in the household on a typical weekday. Enriched census data are examined to calculate the share of each family type in the region of Flanders in Belgium. Next, individual activity-travel sequence patterns are drawn for children and adults. Finally, these individual sequences are combined to family sequence patterns, yielding a concise representation of skeletal information in activity-travel patterns of household members and their interrelationships. This process is tested and the method offers a promising approach to both household activity-travel analysis and travel demand modelling.
