I would like to split a network of roads at the vertices just created in another layer. So, I have got a roads layer and a nodes layer and I would like to exploit the nodes layer in order to obtain a graph from the roads made by edges defined by those nodes.


You can use Esri Split tool. Here you can add your line layer as in features and points layer as split features. Lines would split at nodes location.
