Ensuring the equity and inclusiveness of transport systems,thereby enabling individuals to equally access convenient and reliable transport services,is the key to the construction of inclusive cities.From the perspective of transport and behavioral geography,the travel behavior characteristics of disadvantaged groups and the influencing factors have become a research hotspot.However,the internal causal relationship and complex interaction mechanism between transport disadvantage caused by geospatial imbalance,temporal constraints,and socio-economic characteristics and residents'travel behavior have not been fully explained.Based on the survey data of urban residents'built environment perception and travel behavior in Xi'an in 2022,this study analyzes the characteristics of transport disadvantage under the space-time constraints,and constructs a structural equation model to explore the mechanism and spatial heterogenicity of the impact on urban residents'travel behavior.The result reveals that:(1)The perceived transport disadvantage under the space-time constraints exhibits obvious socio-economic and spatial heterogenicity.Perceived spatial disadvantage is higher for elderly,less educated,non-car owners,and lower annual household incomes.Females and young middle-aged groups are more vulnerable to temporal constraints.Higher perceived transport disadvantage groups cluster in the suburbs.(2)Perceived spatial disadvantage caused by geospatial obstacles and uneven distribution of facilities is a key factor that affects the travel decision-making of transport disadvantaged groups.Bus accessibility,distance to metro stations,and amenity accessibility affect travel frequency by influencing perceived spatial disadvantage.(3)There is spatial heterogenicity in the impact of perceived transport disadvantage on travel frequency,with more significant direct and mediating effects in the suburbs.Perceived spatial disadvantage mediates the relationship between the built environment and individual socio-economic attributes on the travel frequency of transport-disadvantaged groups in suburban areas,while perceived temporal disadvantage significantly mediates the impact of income on resilient travel frequency.This study deepens the understanding of the influencing factors and mechanisms affecting the travel behavior of transport-disadvantaged groups.It provides valuable support and recommendations for optimizing and regulating the spatial environment and social governance strategies from the perspectives of inclusiveness and equity.
