Abstract:

Carsharing is a sustainable, alternative transportation mode, easily implemented at local level. Its service combines characteristics from both private and public transportation, rendering it attractive to specific groups of commuters. In order to increase the demand for carsharing and optimize its operation, the characteristics of the potential users should be investigated. In this paper, the propensity of people to join a carsharing scheme is being modeled using mixed Internet and paper survey data. An ordered logit model is developed, with dependent variable the stated propensity of young Greeks to join carsharing and explanatory demographic characteristics and travel attributes. The satisfaction of the commuters about the current travel patterns is considered as latent variable in the modeling framework. The aim of combining the two datasets is to measure the difference of the variance of the error term generated from the paper and Internet respondents, who are prone to be positive in their responses in order to satisfy the interviewer. This is verified in the current research by the positive sign of the scale parameter applied at the utility function of the Internet-based data. The use of latent classes enhances the model estimation, by measuring the parameters that determine the respondents’ unobserved, underlying behaviors. The results show that people who use taxi for social activity, are of medium to low income and environmental conscious, are more willing to joint the scheme. The results are compared with a 2013 study, in order to identify the advantages of using this advanced modeling framework.
