This is my first time working with a network analysis (ArcMap 10) and there are some problems which haven't been solved until now.
I have bus stops and Streets (with length, slope, time from-to for a pedestrian (2.5 km/h)).
I want to figure out from which point a person in a village can reach the bus stop within 5, 10 and 15 min. ( I did an ESRI tutorial about this topic, and actually it shouldn't be so difficult, but the tutorial data was well prepared) At first I don't want to add slope restrictions. I just want to generate polygons around the bus stops with 5,10 and 15 min.
The result is quite weird. It seems that some streets have been analysed but others haven't been. (see screen)
All roads are connected and they have no further restrictions so i wonder why they are not displayed in analysis.
