Hello! I've tried to build my own public transport network to generate drive time polygons from key places, I don't have any GTFS data for the region but I'm just going to accept that it won't make the results that accurate .
However, when I run the analysis it doesn't give an area like the walking version does even though there are surrounding public transport routes in The area? I've linked pictures below to hopefully explain better? Does anyone know if I have done anything wrong?
thank you for your help!
