>>1054433Pic related is from a study in my city's public transit. It was done by a consulting agency from Karlsruhe, one of the cities with the most extensive public transit systems in the world. They assume that people access a tram/light rail stop from a 400 to 500 meter radius as the crow flies, as you can see in pic related. Thus if you put two tram lines next to each other, they should be 800m to 1000m apart for complete coverage.
