IntroductionThe growing trend of children being driven to school has become a cause of concern in developed countries, with parents' perception of trust in neighbourhoods emerging as a key determinant. Previous research has mainly investigated the influence of either the mother's or the father's perception on children's school travel. While the contribution of each parent's perception to the final decision, and the factors affecting this contribution, remains unclear. MethodsThis study leverages data from the Longitudinal Study of Australian Children (LSAC) to examine the distinct roles of mothers' and fathers' perceptions of trust in the neighbourhood on their children's school travel mode. It proposes a hybrid choice model (HCM) to measure the contribution of each parent's perception as a function of their socio-economic status (SES) in the school travel mode decision. ResultsThe results indicate that a higher parental perception of trust in the neighbourhood significantly reduces the likelihood of using private car to take children to school. The study also identifies several factors that influence parental perception of trust, highlighting differing impacts on mothers and fathers. Neighbourhood SES has a more pronounced positive impact on mothers’ perceptions of trust, whereas homeownership and urban residency exhibit stronger effects on fathers' perceptions. The analysis further delineates the contribution of individual parents to the overall parental perception of trust, demonstrating that higher levels of income decrease this contribution. ConclusionThis study highlights the significant role of parental perception of neighbourhood trust in children's school travel mode, with both mothers' and fathers' perceptions playing crucial roles. Neighbourhood SES, homeownership, urban residence, and ethnic diversity shape parents' perceptions, with differing effects on mothers and fathers. Future policy initiatives should focus on fostering trust and social inclusion through community events, multicultural programs, and social activities to enhance neighbourhood cohesion and support sustainable school travel choices.
