Network Analyst won't Solve Shortest Route

Hi,

I'm new to network analyst and I need some help. I got a road network from the county and created a network dataset. At this point I want to create driving directions between 1 start point and an end point. Sometimes when I plot the two points and then click "solve", it works. However, other times I get an error message and the route will not solve. Any ideas why this may be? Attached is a screenshot of the error.

Thanks,
John

Notice in the Network Analyst window under Stops how one of your stops has a red symbol next to it. That means it didn't get located on the network. So, when you dropped the stop on the map, it wasn't able to snap to one of the streets on your network dataset. Consequently, you can't solve a Route that goes to that point, because the network doesn't know where the point is.

There are a few reasons why your stop might not locate properly on the network:
- The stop isn't close enough to a network edge
- You altered your network location settings in such a way that the point couldn't locate on that type of network edge

I recommend you take a look at these pages in our documentation:
