# Transit Weaver Field Notes

Transit Weaver generated 48 fictional networks across six archetypes and ranked them with local graph and diagram metrics.

## Top Specimen

- Winner: `split-bank-02`, Split Bank 02, score 0.6977.
- Shape: Split Bank.
- Stations: 35; lines: 6; transfer stations: 11.
- Average shortest path: 4.44; bridge edges: 15; crossings: 3.

## Reading The Scores

- Connectedness rewards one coherent reachable network.
- Coverage rewards stations distributed across quadrants and distance bands.
- Resilience rewards cycles and penalizes bridge edges that can split the graph.
- Transfer score favors a useful middle range of interchange stations rather than no transfers or a single overloaded core.
- Directness rewards lower average shortest paths.
- Legibility rewards straighter routes and fewer line crossings in the generated diagram.

## Run Findings

- Best average archetype: Express Spur with average score 0.6762.
- Strong specimens usually pair at least one loop with several cross-city cuts, which reduces bridge dependence without overloading the central station.
- Pure grid and split-bank variants can look readable while scoring lower on resilience when too many trips depend on a small set of bridge edges.
- Express-spur variants are strongest when the fast trunk also lands on transfer stations rather than bypassing the useful mesh.

## Limits

These are fictional diagrams. The metric is a local descriptive lens, not a real planning model. It ignores ridership demand, geography, accessibility, cost, and service frequency.
