I am currently trying to compute car-travel-distances (in km) from a given set of about 50000 point-pairs (origin-destination). I do have the points and the road lines as shapefiles.
I couldn't find yet a smooth automatic solution using ArcGIS NA.
Does anyone have similar experience?
Can anyone help?
You can first make a network dataset from your streets shape files so that you can route on it.
Make sure your Origin and Destination route point pairs have a common ID that can be used to match them up during route solving.
You can create a new route layer. Then load the origin set of points making sure that you map the ID to the ROUTENAME property. Then load the destination set of points making sure that you map the ID to the ROUTENAME property. Now you have basically told the route layer to solve multiple routes like A to B, C to D, E to F, etc., Solve the route layer and you will have all the OD route pairs solved.
