Hello,
I'm trying to create service area polygons for several national park entrance sites to find park participants that live within a 60 minute drive time. I am using the ESRI USA Minor Highways as the basis for my network. I first projected the highways to an equidistant projection, then created a "minutes" field based on the road class (using an estimated mph by class) and segment length. I am working with a small test site now. I created and built a network, and am using the Service Area tool to create polygons.
The problem is that my polygons come out looking very strange, and it appears to me that the solver is only going from one road junction to another, and not using the edges at all. The polygons look "spiked". It does not seem to matter what parameters I set for my polygons. Where did I go wrong?
Thanks in advance!
