SALoT Map is the impression map of environment that integrates the collective information of snapshots (S), attributes (A) of the person who took snapshots, their locations (Lo) and the descriptive texts (T). The procedure is following. The first is the classification of snapshots, attributes and locations. The second is the scoring of texts and snapshots by text-mining and VisualRank. Seventy students of Faculty of Agriculture of The University of Tokyo took part in the survey to find something interest in their student lives. Impression of eight locations such as in-door and outdoor of Yayoi campus, Tanashi farm, home and so on was visualized. The difference of impression between their major fields was also recognized, that is, students in Applied Biology took interested in animals and foods, whereas students in Landscape Ecology took interested in a row of trees. SALoT Map method could be applicable to search attractions in some town.

多摩ニュータウン開発は逼迫する東京圏の住宅需要に応え無秩序なスプロールの回避策として1966年12月に着工された。NTの性格は、当初東京都心に依存したベットタウン的性格もやむを得ずとしていたが、同時に30万人を抱える都市規模で都心直結の鉄道建設も併せ行なう新都市開発であることから逆輸送を促す施策の導入と周辺地域の雇用の場との連携による広域相互依存圏の樹立を目標としてきた。
本稿は、上記の視点に着目し開発理念の構築と再構築の過程を辿り、職住近接を促す (1) センター地区や特定業務施設地区等の寄与と (2) NT新線ルールの創設や都市インフラの高水準化等による支持人口の増加と施設立地等の「計画・事業手段 (Planning & Prolect Tool)」の生成過程とその背景を明らかにした。また、NT市民の日常的活動の変容過程から都心集中型ではなく相互依存型に移行しNTの自立化を促す芽が育まれつつある状況を把握し、計画・事業手段の生成並びにNT市民のライフスタイルや立地企業のビジネススタイルの変化との関係を明らかにした。

A contemporary life style is based on the ability to participate in social activities, such as working in a work place, making purchases in retail stores, taking lessons at a school, and receiving medical treatment at hospitals because modern cities are characterized by high spatial differentiation of various activity opportunities. Persons with physical impairments are, however, restricted by different barriers to access activity opportunities inherent in the urban built environment. The following features of the built environment are barriers in the way of the activities of persons with lower limb impairments: 1) buildings with an entrance that has a level difference, stairs or a heavy door; 2) street paths with a slope, stairs or irregularities; 3) public transportation with stairs at the entrance or a gap between platforms. In an urban space full of such barriers, persons with lower limb impairments have difficulties accessing activity opportunities so that they are prevented from participating in social activities and are thus marginalized from the mainstream of modern society.
This article has two purposes: 1) to examine the characteristics of the urban built environment in terms of barriers that restrict the activities of persons with lower limb impairments; 2) to elucidate the extent of inaccessibility in urban spaces that contain barriers through analysis of spatial accessibility by persons with lower limb impairments to local activity opportunities, taking into account barriers related to entering/exiting buildings and travelling on streets. The author selected the early developed area of Tama New Town, Tokyo, as a study area for the above purposes.
The results of the analysis are summarized as follows. Accessibility measurement values were considerably lower when considering barriers than when not considering barriers. When considering barriers, accessibility decreased dramatically around the main regional center and sub regional center as well as along the main roads, and the distribution of points having relatively high accessibility tended to be localized. On the other hand, the decrease in accessibility when considering barriers was moderate around neighborhood centers, but, in absolute terms, the extent of accessibility was not high. Such (in)accessibility patterns are related to the fact that there are many barriers to travel on streets because of the large undulations in the northern part of the study area, the fact that there are many buildings with barriers at their entrances along the main roads, and the fact that there are many buildings with a flat entrance, with the exception of clinics, in neighborhood centers located in relatively flat areas on pressure ridges.
If one considers that outside stairs, street inclinations and a level difference or stairs at the entrance of buildings represent formidable barriers that cannot be negotiated by persons with lower limb impairments, the results of analysis show that access to activity opportunities by persons with lower limb impairments is restricted to a very considerable degree. Such inaccessibility for persons with physical impairments seems to suggest that Tama New Town is an urban space created for able-bodied persons. However, due to the aging of the local population, discrepancies currently exist between those able-bodied persons who are implicitly assumed to be residents in the development plan and those who actually live in the study area. The results of this article, therefore, suggest that middle-aged or elderly persons are likely to experience severe restriction with regard to social activity participation after becoming physically impaired, since various features of the built environment turn into disabling barriers. This inaccessibility issue is expected to become broadly manifest in residential areas developed on hilly terrain at an early date and where the local population has been aging, such as the area covered by this study.
