Which robot corridors are busiest with transit?
Transit-stop density varies more than fiftyfold across the tracked corridors. LA West Side is the densest at 2,737 measured OpenStreetMap transit stops, so a delivery robot there shares the sidewalk constantly with waiting and moving transit riders. Atlanta reads lowest at 27 stops, but that is almost certainly OSM under-tagging rather than a true absence: MARTA runs a large network the open map has not fully captured. The honest read is that transit density is a real sidewalk-crowding signal where the open data is complete, and a data-coverage caveat where it is not.
Every figure is measured from OpenStreetMap transit-stop tags. How we verify.
Transit stops, ranked densest first
| Corridor | Transit stops | Detail | Basis |
|---|---|---|---|
| LA West Side | 2,737 | 2,737 OSM transit stops. Highest transit density. | Measured |
| Chicago | 949 | 949 OSM transit stops. CTA+Metra. | Measured |
| SF Core | 727 | 727 OSM transit stops. Muni+BART. | Measured |
| Dallas-Fort Worth | 511 | 511 OSM transit stops. DART. | Measured |
| Miami | 448 | 448 OSM transit stops. Metrobus+Metrorail. | Measured |
| Austin | 288 | 288 OSM transit stops. CapMetro. | Measured |
| Alexandria, VA | 185 | 185 OSM transit stops. DASH+Metrobus+WMATA. | Measured |
| Phoenix | 90 | 90 OSM transit stops. Valley Metro. Low density = car-dependent. | Measured |
| Atlanta | 27 | 27 OSM transit stops. LOWEST. MARTA under-tagged in OSM. | Measured |
Source: OpenStreetMap via Overpass API (transit-stop tags). Counts reflect OSM coverage, which is complete in some metros and under-tagged in others.
Why a low count is a coverage caveat, not a finding
OpenStreetMap is community-tagged, so a corridor with a large real transit network can still show few stops if local mappers have not tagged them. Atlanta at 27 is the clear example: its rail and bus network is large, so the low count is an open-data gap, not a quiet street. Where OSM coverage is complete, the density figure is a real signal of how much a robot shares the sidewalk with transit riders.

Every transit-stop count is measured from OpenStreetMap transit tags via the Overpass API and carries the Measured basis. OSM is community-tagged, so a low count can reflect under-tagging rather than a true low, which is stated on every affected row. These are measured-from-open-data facts, not reviewed DEPLOY registry records, so none carries the registry verified chip. How we verify
