Editing network for shortest path

Question

I am editing road network to create scenarios but Shortest Path is not recognizing the edits. I am assuming the edited street network is not connecting with other streets at intersections. I have extended yellow line to meet the red line but Shortest path is not recognizing the connection.

Could anyone please tell me how to solve this issue please?

Answer 1

In order to use those lines as connected you have to make a node in the line where you have trying to connect the new one. So.

1. Add a node (cut the line).
2. Use snap tool (the magnet icon) con start editing from that node.

In case that Shortest Path still doesn't work, try to pass v.clean (grass tools) to correct other ussues lines could have.
