Thunderforest, OpenStreetMap contributors: Transportation Layer

Description:

The transportation layer on PolicyMap comes from Thunderforest, a project founded by Andy Allen and operated by Gravitystorm Limited.

The layer shows bus and rail lines, stations, and stops throughout the United States at various geographies. Additionally, the layer includes freight and passenger rail. Passenger rail lines include local transit authorities, regional lines, and Amtrak. Stations for local and regional lines appear when the user zooms into the map. Amtrak stations appear when the user zooms out of the map. Additionally, novelty rail lines appear on the map that does not connect passengers to destinations. In current rail projects, some display future stations even if they are not currently operational, while others do not appear on the layer.

Freight lines like CSX, Norfolk Southern, etc., appear on the map, but do not include station stops. Also, freight lines connected to companies or rail yards appear. Some local passenger rail lines include bus service connections for the last mile at terminating stations. Users need to confirm whether a rail line continues or a shuttle service begins as the layer elements do not differ.

Bus routes and stops include local transit authorities, local shuttles, long-range buses, and regional bus services. The layer does not differentiate between services or authorities; it only consists of the route number for each line. Some bus routes are private services and do not reflect public transportation. Only the start and end stations are available for long-range buses; intermediate stops do not appear on the layer.
