Problems with Bridges in Network Preparation« Back to Questions List

Hi Pedro. As I have stated on LinkedIn your work is really cool. I think the node creation process in Network Preparation is a little harsh when it comes to bridges. Two roads crossing without a common vertex would I normally regard as an out of level crossing. In Network Preparation it is transformed to a node and will be regarded as an intersection in the model I assume? I know in some situations with a very "dirty" coded network you would like this behaviour, but perhaps there could be at switch whether you want this behaviour or net?

It is definitely not difficult to do, and I’ll include that request in the list of features to be implemented. Thanks for the input.

You are right – I don’t know what happened, I cannot repeat it!

Would it be possible in a future version to get the number of connected links in each node in the node file? This could be good as QA for spotting unintentional dead ends (missing snapping) and nodes with just two connected links that could be eliminated.

Hi Morten, The network preparation only puts a node if two links have extremities on the same lat/long. If you have two links crossing (like a bridge crossing over a road), then you would NOT see a node in their crossing, as the algorithm behind the procedure only looks into the extremities of the links and analyze them as the nodes that need to be matched. Please go ahead and check the network by selecting the links you are looking into and seeing where their extremities are.
