まとめ
セントルイスは街の密度が最適ですが 理想的な人口密度や公共交通機関へのアクセスには欠けています 政策は存在するものの 質は低いため 都市での居住可能性の評価は困難です
科学分野:
- 都市計画
- 公衆衛生
- 環境科学
背景:
- 居住可能な都市は 安全,健康,包摂性,持続可能性,住宅,移動性,機会を優先します
- グローバル・オブザーバトリー・オブ・ヘルシー・アンド・サステイナブル・シティ (GOHSC) は,世界の都市における健康と持続可能性の評価のための1000都市チャレンジを開発しました.
研究 の 目的:
- ミズーリ州セントルイスの居住可能性を GOHSCの空間と政策指標を使って評価する.
- 都市計画と持続可能性政策に関連して,建築環境と交通の特徴の空間的分布を分析する.
主な方法:
- オープンデータから空間指標を分析し,政策文書をコード化することで,混合方法のアプローチが採用されました.
- 政策文書は,ガバナンスレベル,健康的な都市の証拠との連携,そして測定可能な目標の含有について評価されました.
- 空間的指標には,通り交差点の密度,人口密度,公共交通機関の接近度,公共のオープンスペースへのアクセスが含まれています.
主要な成果:
- 住民の91.7%が最適な交差点密度のある地区に住んでいた.
- 最適な人口密度地域には2.8%しか住んでおらず,公共交通機関に近い地域には26.3%しか住んでいない.
- 44.5%が広大な公共スペースにアクセスでき,GOHSCの都市平均を下回った.
- 政策の範囲は良好だが,質は低い (31%),その多くは測定可能な目標がない.
結論:
- 都市での住みやすさを評価するための包括的な枠組みを 空間指標と政策指標が提供しています
- セントルイスは住みやすさ指標で混雑した結果を示しており,人口密度,交通アクセス,政策の質で大きなギャップがあります.
- 将来の研究は,より深い居住可能性の分析のために,環境正義とマイクロスケールのストリートスケープデータを統合する必要があります.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
100
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

Levels of Use of a GIS
100
Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...

Design Example: Sustainability in Concrete Building
225
As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...

Selected Data About Geographic Locations
69
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Thematic Layering in GIS
77
In the past, planning projects such as schools or public facilities required extensive manual effort to gather and compile data. Information such as property boundaries, soil characteristics, road networks, zoning regulations, and flood zones had to be sourced individually from courthouses, utility providers, and registry offices. Assembling these datasets into a coherent format often took several months, delaying project timelines.The introduction of Geographic Information Systems (GIS)...
