“…That is, the framework of HCM that has been developed to enrich the behavioral realism of DCM by accounting for latent factors such as perceptions and attitudes and employing more flexible error structures. The framework of the HCM has been applied in various transportation contexts, such as mode choice (Johansson et al 2006;Polydoropoulou et al 2013;, vehicle purchase (Bolduc et al 2008) and route choice (Tsirimpa and Polydoropoulou 2007).…”

Incorporating social interaction into hybrid choice models

The aim of this paper is to develop a methodological framework for the incorporation of social interaction effects into choice models. The developed method provides insights for modeling the effect of social interaction on the formation of psychological factors (latent variables) and on the decision-making process. The assumption is based on the fact that the way the decision maker anticipates and processes the information regarding the behavior and the choices exhibited in her/his social environment, affects her/ his attitudes and perceptions, which in turn affect her/his choices. The proposed method integrates choice models with decision makers' psychological factors and latent social interaction. The model structure is simultaneously estimated providing an improvement over sequential methods as it provides consistent and efficient estimates of the parameters. The methodology is tested within the context of a household aiming to identify the social interaction effects between teenagers and their parents regarding walking-loving behavior and then the effect of this on mode to school choice behavior. The sample consists of 9,714 participants aged from 12 to 18 years old, representing 21 % of the adolescent population of Cyprus. The findings from the case study indicate that if the teenagers anticipate that their parents are walking lovers, then this increases the probability of teenagers to be walking-lovers too and in turn to choose walking to school. Generally, the findings from the application result in: (a) improvements in the explanatory power of choice models, Transportation (2014) 41:1263-1285 DOI 10.1007 (b) latent variables that are statistically significant, and (c) a real-world behavioral representation that includes the social interaction effect.

“…The estimation of the fourth method was resolved both by classical methods (likelihood function) (Ben-Akivaet al, 2009;Bolduc et al, 2008) and Bayesian methods . However, the simultaneous model system is quite complex to solve.…”

Several international studies have analyzed the acceptability of road pricing schemes by means of an attitude survey in combination with the results of a stated choice experiment using both a descriptive analysis and a discrete-choice model with binary choice ("accept" or "not accept" the toll). However, the use of hybrid discrete choice models constitutes an innovative alternative for integrating subjective attitudes and perceptions deriving from the survey of attitudes with the more objective variables from the stated choice experiment. This paper analyzes the results of applying these models to measure the acceptability of interurban road pricing among different groups of stakeholders (road freight and passenger operators, highway concessionaires, and associations of private car users) with qualitatively significant opinions on road pricing measures. Our results show that hybrid models are better suited to explaining the acceptability of a road pricing scheme by different groups of stakeholders than a separate analysis of the survey of attitudes and a discrete-choice model applied on a stated choice experiment. A particular finding was that the strong psycho-social latent variable of the perception of fairness explains the rejection or acceptance of a toll scheme by road stakeholders.

“…Recently, car-choice studies have started to incorporate other aspects as well-mainly behavioral and attitudinal aspects of the purchasing household; some of these attributes imply that the car has some other values than purely functional. Typically, the attitudes to new technology are included when studying the uptake of alternative fuel vehicles, including hybrids and electric vehicles (Bolduc et al 2008;Eppstein et al 2011;Ewing and Sarigöllü 2000;Hidrue et al 2011). There is thus an implication that new technology can have a value for the consumer that is separated from the pure functional value of the car.…”

Unbundling cars to daily use and infrequent use vehicles—the potential role of car sharing

Car sharing is seen as an alternative to car ownership; however, for many households, this option may be unthinkable. In this study, we explore the idea of combining car sharing and vehicle ownership in order to change car purchase behavior to improve the environmental performance of the fleet. We consider the personal vehicle as a bundle of attributes. We look at the distinction between Bdaily use^and Binfrequent useâ ttributes. BInfrequent use^features are those that are only needed occasionally, e.g., a larger trunk, all-wheel drive, seating for 7, and long vehicle range. If the vehicle attributes could be unbundled, the personal vehicle would include only those features needed on a daily basis, with car sharing providing the Binfrequent use^features. We qualitatively explore what the carsharing service would need to look like to cover the Binfrequent use^needs and analyze if the existing services can provide these needs. We base our analysis on literature and interviews with experts and representatives from car sharing and rental car companies in California and Sweden. We find that car sharing today does not cover the needs for unbundling the vehicle. There are not enough Binfrequent use^vehicles available in these services. However, new business models and the growth of peer-to-peer car sharing are already begun to widen the vehicle models available.
