Hi Dan, I set up a new network dataset and was able to apply a speed limit of 60p.h, however, when I run find nearest facility, still no output (see left column)

Hi Dan, I was able to add a time field in my table but I can't use field calculator to set a time, see blue... (eg. (length/mph*60)). I can't input that formula for some reason...

Hi Dan, Thank you as always for speedy reply. Could you detail the step by step process I would need to undertake to do this? I am not per se interested in speed / time, however, I have googled the process and tried to add time but the analysis keeps failing, see below, I have added parameters and evaluators (at least I think I have!) and still not working. Any advice would be very helpful. Neither data inputs have a time table, which I have tried to add using field calculator but it won't give me that option...

Hi Dan, Thanks for prompt response - I have setup a network dataset (shape file) that has streets and junctions, however, when I go into the properties toolbar to change the attributes of the network the only attribute listed is length, with no time component. Could you offer advice on how I might fix this? The XY are the resident locations, the greenspace file is the vertices of the green space, however, the network dataset is coming up as an error? The distance is the length, but why do I need to assign time to this?

Hi All, One last question: I am using Network Analyst to find the nearest distance to a park from a resident's location (i have converted the park polygons to line and then vertices). I keep getting this error? Could someone suggest an alternate?

Hi All, Up until now, everyone on this forum has saved my bacon, so I thougt I would try my luck again! I am counting facilites (points) within buffers using spatial joing and sum, the problem, however, is this: when I do a 'blind eye' count, the count is 2, for example, in buffer A yet when I look at the spatial join count it shows as 10! Could someone suggest why this would occur? The points are listed as "multipoints" in the geography type, would this distort the count and if yes, how do I rectify this issue? Thanking you in advance!

Hi Everyone, I tried those techniques and while the union worked, when I dissolved the polygons, it merged into other separate files. Each polygon is a walkability buffer network, and I need to keep them separate. I want to create a "solid" buffer so that I can analyze other factors such as the amount of PT stops within the buffer. I have eliminate polygon which I also tried and didn't seem to work. Will the python code troubleshoot this do you think?
