| Research Abstract |
In this fiscal year, the following two types of studies were conducted.
(1)Comparative analysis of group discrete choice models in case of household vehicle type choice : Five operational models related to group discrete choice are dealt with : Multi-linear Model, Autocracy Model, Max-Min Model, Max-Max Model, and Minimum Endorsement Model. Based on a revealed preference data collected with respect to household car ownership and use in Hiroshima metropolitan area in 2004, it was confirmed that the model accuracies are all sufficiently high, but the differences are not significantly large. This suggests that there might exist several decision-making rules in this case study. It is also made clear that the sensitivity of vehicle body price in the multi-linear model is the lowest than that in other models, and the price sensitivity differs across vehicles. Therefore, in the application to policy analysis, one needs to carefully select the appropriate models.
(2)Analysis of household residential choice based on a web-based stated preference survey : This study conducts a web-based stated preference survey to investigate households' preferences for moving to the assumed residential areas along the Astramline, a transit system in Hiroshima City in 2005. The respondents were asked to first report their actual group decision-making methods with respect to some major choice situations within their households. They were further asked to first separately, and then jointly choose the most preferred residential area and the commuting travel mode from a choice set, which also includes "not-move" as an alternative. It is found that joint decisions lead to the changes of members' preferences in about 40% of the household. It is also concluded that high-rising housing close to the Astramline could attract more people to live in and consequently contribute to the effective use of the transit system.
