Modelling mobility tool ownership using a global indicator for accessibility

Abstract

Mobility tool ownership, meaning the availability of resources that enable a person to use a particular transport system such as a car or a season ticket for public transport, is one of the most important factors influencing individual travel behavior. It is obvious that transport supply has an impact on this variable. For this reason, it should be determined integrally on a modeldriven basis in travel demand models. The paper suggests a global indicator describing accessibility to be applied in this matter. The indicator is calculated based on the results of travel demand modelling, namely a combination of trip generation, trip destination and mode choice. It is implemented in a non-spatial travel demand model at municipal level. An example illustrates the effect and importance of considering mobility tool choice in strategic transport planning.
