Abstract

過疎地域などの公共交通サービス水準が低い地域では,住民はその環境に適応して活動のニーズを低めに形成する可能性がある.故に公共交通計画を策定する際,住民の活動機会に着目すべきである. 著者らは活動機会の大きさを測定する一連のアクセシビリティ指標を提案している.しかし,公共交通利用者の活動機会に影響を与えると考えられるバスダイヤ,バス停までの歩行による疲労,活動を行う施設の営業時間帯などといった要素を統合的に評価するような指標は存在しない.そこで,本研究では既往研究を踏まえ,公共交通利用者の活動機会の大きさを測定する指標を構築する.さらに,指標を計画情報として用いる場合の測定法を提案する.

In planning public transport, the major interest is to satisfy the needs of residents. However in the area with poor public transport service, the need may be formed too small because of adaptive recognition. That is to say it is necessary to focus on "activity opportunities" instead of "needs", in planning public transport. The richness of activity opportunity possessed by residents can be evaluated at how many of places they can visit to act, how flexible they can act in time, and how short they can reach these places. We supposed a series of accessibility index to measure the level of activity opportunity. But there is no accessibility index dealing with components, which may influence activity opportunity, such as the diagram, physical fatigue from walking, and business hours of facilities, comprehensively. Then, this study aims to propose an accessibility index developed by integrating these previous studies. Through a case study, the order of estimated values of accessibility index of places to the city center and the order of subjective level of accessibility of the places shows good fitness.
