Hi, sorry for not being clear enough. So, I have routes of different bus numbers and I would like to find out how many different green spaces can one access from each bus stop with a cut-off value of 25min. This cut-off value is actually the whole travel time, not just traveling along the route. When I calculated The closest facility, some routes from incidents to facilities combine changing bus 3 or 4 times (which in reality means that commuting time extends to more than 25min). Is there perhaps a possibility of taking this into account? So that when a route from incident to facility demands changing bus, some more minutes would be added to the whole travel time? My only idea of how to do that would be to add interchange stops as barriers but then I don't know how that could be taken into account in order to achieve the 25min traveling time in whole. hope this makes some sense. vita

Thanks for fast answers! The closest facility works well. Since some of my green spaces are really big, I converted green space polygons into points with a combination of creating centroids, making intersections (thanks for that clue!) and adjusting Tolerance distance to facility locations. I was wondering: would it be possible to restrain the routes to one interchange only (regardless if the max cut-off value is not met)? Would I need to set this up in the attributes of the route network or perhaps with The Closest Facility Barriers? Vita

Hi there, I would like to calculate how many different green space types (e.g. parks, playgrounds) are accessible by bus; cut-off value is 25min. I have 11 shape files with different types of green spaces (polygons). I created bus routes for each bus number. So my question is how can I calculate how many green spaces are in the accessibility range after commuting from each bus stop for 25min along every bus route? Is Network Analyst Layer the right tool for this? Vita

Hi, I have the same "Warning" problem, I read through various forums and threads and still havent found the solution. I am trzing to create bus routes using Network Analyst Layer. I created shape file of the whole bus network and its stops, and also separate shapefiles for each bus line. When I load the stops of each bus line and choose New Route, I get this warning. I have no idea what am I doing wrong, the lines are connected, etc. If anyone has some ideas, I would appreciate. Thanks, vita
