Route solver does not find a route

[ConnieSu]

Hello!

I've a road network (2 network classes) and I need to find the shortest cost route between 100 pairs of Origin and Destination points. The Route solver only found 26 out of 100 pairs.

However, when I look at the OD pairs with no route, it seems that they are connected by the road network, but the solver is not finding a solution. For instance, in the picture below there is one OD pair with no route found.

I've already used the Integrate tool in the network classes and I've also created a Topology (with the rules "must not have pseudo nodes" and "must not have dangles").

What else could I do to find routes for all OD pairs?

Melinda Morang‌ , could you please help me?

Thanks and regards!

If your network dataset has been built, you can add it a map in ArcGIS Pro and use the Network Dataset Layer, Data tab to bring up the Explore Network tool. Use that tool to look at the connectivity of the edges. This might help find potential issues with the network connectivity.
