Changes in Travel Behavior of Commuters between 1970 and 2000

Abstract

The paper describes research on estimating sequential discrete choice models for mode choice, destination choice, and interzonal trip generation of commuters from 1970 to 2000 in Switzerland. The research was based on detailed data sets that tracked the development of private and public transportation systems and the socioeconomic variables at the local municipality level. Major changes in mode choice were identified by use of the estimated parameters of travel cost, quantity-adjusted car ownership cost, and car ownership per licensed driver. The results of the interzonal trip generation showed that demand reacted with positive elasticity to accessibility and that the accessibility of a zone became less important for the generation of interzonal work trips over time.
