How split road lines at vertices and divide lengths accordingly?

I am working with Network Analyst, but my road dataset needs to be fixed so that NA can find shortest routes..  Some roads have been drawn to skip right over vertices where intersections are present.  NA would find better routes, if all intersections were really available.

 

I have used the "split line at vertex" tool, and it does a marvelous job of splitting up the roads.  But it does not divide the distances among the various splits.  The same mileage numbers, for example, simply transfer over to all splits made on a given line.   I want NA to be able to report on the lengths of the routes

 

What's the better way to split the roads at intersections and have the software calculate new, correct distances (lengths)?
