Outline of Final Research Achievements

Aiming to realize an environmentally sustainable urban structure and transportation system, the location guidance and transport policy in a regional urban area can be evaluated in consideration of social interaction.
As a result, [1] the relationship between health awareness and intention to refrain from using cars was verified. [2] The effect of promoting EV choice can be estimated in consideration of individual heterogeneity. [3] In the housing location, the influence of the affection to the area was clarified as well as the neighboring land value and the traffic convenience. [4] The influence of the availability of public transport on the frequency of going out was clarified. [5] The simulator has been constructed by combining the residence choice model with the travel behavior simulator including the vehicle choice model and the transport mode choice model. [6] The scenario consisting of location guidance and transport policy can be evaluated.

Academic Significance and Societal Importance of the Research Achievements

都市活動者の意思決定過程として，立地誘導政策に対応した居住地選択モデルと都市交通政策に対応した保有車種更新モデルおよび交通行動モデルを構築することで，居住地，保有車種および自動車利用の相互関係を考慮して，段階的な都市政策シナリオの評価が可能となっている．これにより，多様な主体の複雑な相互作用を考慮して，立地誘導および交通政策からなる都市政策シナリオについて，温室効果ガス排出量の削減に加えて，生活利便性，災害リスク，健康寿命など持続可能性に関する観点から総合的な評価を可能としている．
