Item Reaction to the paper Tempest in a Teapot: The exaggerated problem of transport-related residential self-selection as a source of error in empirical studies(Journal of Transport and Land Use, 2014) Van Wee, Bert; Boarnet, MarlonThis is a reaction to the paper available at https://hdl.handle.net/11299/171222.Item Residential location, travel, and energy use in the Hangzhou Metropolitan Area(Journal of Transport and Land Use, 2010) Naess, PetterThis paper presents the results of a study examining the influence of residential location on travel behavior in the Hangzhou Metropolitan Area, China. The location of the dwelling relative to the center hierarchy of the metropolitan area is found to exert a considerable influence on the travel behavior of the respondents. On average, living close to the center of Hangzhou contributes to less overall travel, a higher proportion of trips by bicycle and on foot, and lower consumption of energy for transport. The location of the dwelling relative to the closest second-order and third-order center also influences travel, but not to the same extent as proximity to the city center. These geographical differences in travel behavior are independent of residential preferences and of attitudes toward transport and environmental issues, and therefore cannot be explained by residential self-selection.Item Response to Van Wee and Boarnet(Journal of Transport and Land Use, 2014) Naess, PetterThis is a reaction to the paper available at https://hdl.handle.net/11299/171221.Item Spatial self-selection in land-use–travel behavior interactions: Accounting simultaneously for attitudes and socioeconomic characteristics(Journal of Transport and Land Use, 2014) Abreu e Silva, João deSpatial self-selection can be ascribed to two main factors: socioeconomic characteristics or attitudinal aspects towards travel and location choices. Several studies have investigated the influence of self-selection on the relations between travel behavior and land-use patterns. So far the results could be considered mixed. The model proposed herein uses data collected in 2009 for the Lisbon Metropolitan Area. A structural equations model was built to study the effects of spatial self-selection due to both socioeconomic and attitudinal effects. Three model specifications were considered: one treating attitudes toward travel as exogenous and two others considering them as endogenous. The preferred specification considered attitudes as exogenous. The land-use patterns are described by factors both at the residence and employment zones of each individual. The travel behavior variables included here are multidimensional and include commuting distance, car ownership, the number of trips by mode, and the total amount of time between the first and last trips. On account of the data characteristics and sample size, Bayesian estimation, as implemented in AMOSTM software, was used. The results obtained show that although the attitudinal variables significantly influence travel behavior, they do not annul the effects of land-use patterns in also contributing to shape the same behavior.Item Tempest in a teapot: The exaggerated problem of transport-related residential self-selection as a source of error in empirical studies(Journal of Transport and Land Use, 2014) Naess, PetterWhile numerous studies have investigated influences of built environment characteristics on travel behavior, many scholars are concerned about the confounding effect of residential self-selection. This paper argues that the existence of transport-attitude-based residential self-selection hardly represents any threat to the validity of the basic knowledge on how residential location within urban contexts influences travel behavior. The causal mechanisms by which residential location influences travel behavior exist regardless of whether or not transport-related residential self-selection occurs. Moreover, the cases presented in this paper suggest that residential self-selection based on attitudes to travel is unlikely to represent any great source of error for parameter estimates of the effects of residential location variables on travel behavior as long as “traditional” demographic and socioeconomic variables have already been accounted for. The doubts raised by certain scholars about the implications of attitude-based residential self-selection for the validity of the knowledge base of land use and transportation policies thus appear to be not very well-founded.
