Mobility constraints and accessibility to work: Application to Stockholm

Abstract

This paper investigates workplace accessibility in Stockholm through a workplace choice model within a space–time prism concept. We develop a workplace accessibility measure that incorporates individuals’ constraints in time, space, and resources. The accessibility measure is derived from an activity-based demand model formulated as a Markov decision process in a dynamic discrete choice framework, where space–time constraints affect the possibilities of individuals to engage in activities during spare time. Indeed, the results show that spare time accessibility is significantly linked to workplace accessibility. Applications of the results show how space–time constraints, such as access to a car or having children, affect benefits in terms of consumer surplus for relocating a large workplace (a hospital in our case), car dependency, and segregation.
