Network Analysis - route to closest point on network

Shane_EU — Fri, 28 Jun 2024 08:38:04 GMT

Hi, how can I use network analyst to find a route to the closest point on the network to a destination that is not on the network (the image depicts the problem).

Thanks!

During network analysis, you add "stops" using Add Locations (Network Analyst)
That tool has a Search Tolerance parameter. There is also a Snap to Network parameter.
You'll need to set the search tolerance to be at least the maximum observed offset of an origin or destination from the network. The snap to network parameter can be used to show the closest navigable location on the network.

Without color code lines, it is difficult to understand your question. Network Analyst will only draw a route on the Network Streets.
If the Yellow is the Solved Route, that may be the closest Network Street that can be traversed. What is the line at Stop 2? Is it a walkway or driveway? Whichever, it doesn't seem to be part of the Network Streets.

I have been using ArcMap with the ESRI Street Maps Premium, which has many errors and omissions. My Network Route Line is Pink, so I make sure the Network Location is on the closest navigable street at the driveway, then I manually draw in any complicated driveways or roads for my field agents to use for visual reference. If you maintain your own Streets Network Dataset, you could edit those lines and add as Network Streets.

In the example, Stop 24 was used to create a Source OID and the PosAlong values to enter for stops 21-23.
