Network Analysis
Treats a city's roads and transit routes as a connected graph, to find bottlenecks, gaps and structurally disadvantaged nodes.
Infrastructure
When It's Useful
When the question is about structure — where a network is fragile, redundant, or disconnected — rather than about any single trip.
STRENGTHS
- Identifies chokepoints invisible from any one commuter's perspective.
- Quantifies redundancy and resilience of a transport network.
- Useful for comparing infrastructure investment across areas.
LIMITATIONS
- Abstracts away individual experience and cost.
- Sensitive to how the network is defined and cleaned.
- Can overstate the importance of formally mapped routes over informal ones.
