I am currently trying to build my first multimodal network using ArcGis 9.2. This is a test using simple data of what I will need to do later with more complex data.

Here is my data:

  • layer 1: One shapefile containing a line feature. It's the main road.

  • layer 2: One shapefile containing a polyline feature. These are the secondary roads.

My problem is that layer 1 has not been created as connected to the features in layer 2 (created as a long line). As a consequence, there is no vertex where two features intersect, they simply overlap.

To be clearer here is a picture:

enter image description here

The blue line is layer 1, the black ones is layer 2 (all the vertices belong to the feature where they stand).

How can I make to overlapping lines intersect so they can understood as connected when I build my network?

Try using the Integrate tool - that should create the vertices where lines intersect that you are after.

Integrate is used to maintain the integrity of shared feature boundaries by making features coincident if they fall within the specified x,y tolerance. Features that fall within the specified x,y tolerance are considered identical or coincident.
