Numeric Network Analysis for Pedestrians
Lecture and NNA Workshop for Social Algorithm 7.0
1st Lecture
Contents
1. Urban Design Quality and Walkability
: Street type & Walking culture / Built environment factors and active accessibility (3Ds — Density, Diversity & Design)
2. Spatial Network Analysis in Transportation Geography
: How important is the location in the city? Is the place easy to access? or What is your walking route?
: Euclidean Distance vs. Network Distance / Distance Decay / Weights / Centrality Analysis (Betweenness, Closeness, Straightness, Degree) with NNA examples / Accessibility Analysis (Reach, Gravity, Huff model) with NNA examples
: Project in Cambridge, “How do pedestrians choose routes during evening peak hours?”
3. Examples of Numeric Network Analysis using the NNA Toolbox
: About NNA Toolbox
: Ex1. Centrality Test (understand the hierarchical context) / Ex2. Centrality Test (connection efficiency, Cafe vs. Cultural) / Ex 3. Who visits the SQs the most? How far are you willing to walk to Squares? (Accessibility) / Ex 4. what is my chance to visit Union Square from the cafe? (Huff) / Ex 5. Building circulation & evacuation plan (Centrality & Accessibility)
4. On-site Survey and Post COVID-19 Urbanism
