How does transit in places such as Europe do so well despite the longer distances between stops?It's difficult to measure distance between stops for most European transit because their GTFS schedules do not include the optional shape files. I have tried to derive a universal tool for measuring distance to nearest subway/bus/tram stops. I've used the Open Street Map data that supplies building, bus, tram, and subway entrance locations. I've used Open Street Map's road network map to trace the nearest bus stop walking distance from all the buildings within an area. This depends on Open Street Map's accuracy. This can be problematic because it depends on volunteers for its accuracy. I've also used igraph and osmnx tools to measure the actual walking distance, rather than cartesion distance. The generally accepted criterion for walking distance to subway entrances and bus/tram stops is 800m and 400m, respectively. This is approximately 1/2 and 1/4 mile. It would appear that Washington transit stops are already further away than most major world and US cities. However, this might be due to deficiencies in Open Street Map's bus/tram stop location data. The percentage of buildings that lie within these criteria for Washington DC are: 23% and 56%, respectively. The percentages for buildings in London's 33 boroughs are: 24% (subways); 75% (bus/tram). The percentages for buildings in Paris' 20 arrondissements are: 97% (subways); 95% (bus/tram). If Greater Paris is considered, the percentages are: 27% (metro/rer); 81% (bus/tram). Berlin: 16% (subway); 60% (bus/tram). NYC: 21% (subways); 73% (buses). Philadelphia: 11% (subways); 86% (bus/tram). I used the GTFS bus/tram stop locations for SEPTA because the Open Street Map missed a lot of bus/tram stops. The same may be true for some other abovementioned cities. |
