| 47 | +# How is OS-CONNECT different from GTFS-Pathways? |
| 48 | + |
| 49 | +## Short Answer |
| 50 | + |
| 51 | +OS-CONNECT is Washington's connected pedestrian network dataset. GTFS-Pathways is an expansion of the General Transit Feed Specification (GTFS) for describing pathways and transfers inside a transit station or stop. |
| 52 | + |
| 53 | +Use OS-CONNECT for pedestrian-network context outside the station and use a transit agency's GTFS-Pathways data for station-internal connections when the published feed provides those records. A trip-planning analysis may need both datasets because they describe different parts of the journey. |
| 54 | + |
| 55 | +## Significance |
| 56 | + |
| 57 | +The distinction affects dataset selection, routing, and the interpretation of accessibility information. Treating one source as a replacement for the other can omit either the surrounding pedestrian network or the station's internal layout. |
| 58 | + |
| 59 | +## What This Means |
| 60 | + |
| 61 | +- OS-CONNECT represents a connected pedestrian network in Washington State, including sidewalks, crossings, curb ramps, and related pedestrian infrastructure. |
| 62 | +- GTFS-Pathways represents connections among transit-facility nodes, such as entrances, platforms, elevators, stairs, escalators, and walkways, through GTFS records such as `pathways.txt`, `levels.txt`, and related `stops.txt` records. |
| 63 | +- OS-CONNECT and GTFS-Pathways can be combined at a station entrance, but the connection between datasets must be checked rather than assumed. |
| 64 | +- Actual coverage depends on the published dataset or feed version. Inspect the records and documentation before relying on a feature or accessibility value. |
| 65 | + |
| 66 | +## What This Does Not Mean |
| 67 | + |
| 68 | +- OS-CONNECT is not automatically the authoritative source for a transit agency's station-internal pathways. |
| 69 | +- GTFS-Pathways is not a complete connected pedestrian network for Washington State or the streets around a station. |
| 70 | +- A matching map location does not prove that the two datasets share a routable connection. |
| 71 | +- An accessibility attribute in either source does not guarantee that current physical conditions are accessible or unchanged. |
| 72 | + |
| 73 | +## How To Use This |
| 74 | + |
| 75 | +- **Planners and jurisdictions:** Define the geographic boundary of the analysis first. Use GTFS-Pathways for station-internal movement and OS-CONNECT for the surrounding pedestrian approach, then document the feed and dataset versions. |
| 76 | +- **Trip-planning integrators and developers:** Inspect the agency feed for `pathways.txt`, `levels.txt`, and the related `stops.txt` hierarchy. Check station entrances and nearby pedestrian features before joining the two networks. |
| 77 | +- **Advocates and public users:** Ask which source supports a specific accessibility claim and whether the source is current. For a current physical condition, verify with the transit agency or another qualified source. |
| 78 | + |
| 79 | +## Example |
| 80 | + |
| 81 | +A regional planner evaluates an accessible route from a sidewalk to a station platform. The planner uses OS-CONNECT to examine the sidewalk and crossing leading to the station entrance, then checks the transit agency's GTFS-Pathways records for the entrance, elevator, and platform connections. If either source lacks the needed records, the planner reports the gap instead of assuming that the route is continuous. |
| 82 | + |
| 83 | +## Assistant Guidance |
| 84 | + |
| 85 | +Explain the difference in geographic scope. Verify the current OS-CONNECT release and transit feed contents before answering any specific questions about coverage or accessibility. If the user does not identify a dataset version, station, or jurisdiction when that context affects the answer, ask for it or state the limitation. Do not present either dataset as a legal compliance determination or a guarantee of current physical accessibility. |
