A new concept of accessibility to personal activities: development of theory and application to an empirical study of mobility resource holdings

How Personal Accessibility and Frequency of Travel Affect Ownership Decisions on Mobility Resources

“…This study continues the development and application of a mobility-resource ownership model structure originally proposed by Le Vine [1]. Unlike in the original model, here the travel utility component is decomposed into two terms.…”

“…Commins and Nolan [8] also support the claim that transport supply characteristics (costs, travel times) affect vehicle ownership. Le Vine [1] advanced the latter approach and explored the link between using and owning mobility resources given a certain degree of supply provision. This led to the development of the concept: Perceived Activity Set (PAS).…”

“…Hypothetically, this may even reinforce the bicycle as the mode of transport for other travel activities. Le Vine et al [1] has estimated the importance of different travel activity purpose types (e.g., to work, leisure, shopping). Astegiano et al [9] also used the PAS concept, but the importance of a particular travel type was set a priori, being proportional to their frequency.…”

“…The term RCS refers to the fact that the modal choice for daily trip making is restricted by the subset of modes enabled by the chosen RCS. The model structure introduced by Le Vine et al [1] quantifies the utility of a certain RCS alternative perceived by people as the sum of two components. The first component encapsulates non-travel utility associated with owning mobility resources belonging to the given RCS.…”

“…It also makes her likely to buy a new car when facing a decision to update her mobility resources. Le Vine [1] has formalized such a functional relationship using the maximum random utility of the discrete choice model. His model assumes rational decision-makers develop their mobility-resources ownership decisions by balancing the utilities projected over the short-and long-term.…”
