In order to get the final travel time and cost skims from an assigned network it is necessary to pass the loaded network back through the Highway program and build and skim the paths from the loaded network.

This is done in the example below through the programs structure shown in the picture:

For example, simply skimming link field TIME_1 from the loaded network (output from Highway 1) through the PATHTRACE function in Highway program 2 (no iterations), as shown below:

The skimmed values will be the skimmed cost for the “final assignment” network over the minimum cost path calculated with the final combined volumes.

The TURNPENO file allows the movement delays computed by the Junction Model to be included in the path skims by using the TURNPENO file from the assignment as the TURNPENI file for the skims. As in the screenshot below.

And adding the PENI statement within the PATHLOAD.
