Mobility Analysis

A Claude Code skill that researches transit and mobility for any site — subway, bus, bike, pedestrian infrastructure, walk scores, and airport access using transit authority and public data sources.

What it does

Type /mobility-analysis with an address. Claude searches transit authority data and produces a structured mobility analysis covering public transit, roads, pedestrian infrastructure, and cycling. Each transit station includes distance and estimated walk time.

2. NYC DOT — Bike lane maps, pedestrian infrastructure
3. Walk Score — Walkability, transit, and bike scores

## Gaps & Caveats

- Walk Score values are algorithmically generated and may not reflect
  actual pedestrian experience (e.g., construction detours, sidewalk
  quality, perceived safety).
- Bus frequencies are scheduled peak-hour values. Actual frequency
  varies by time of day and day of week.
- Airport drive times are estimates and vary significantly with
  traffic, time of day, and route choice.
- Citi Bike dock counts are current as of data retrieval. Station
  capacity may change with seasonal rebalancing.
- The Pier 40 ferry service is seasonal — verify operating schedule
  for winter months.
