I would like to display highway travel times between cities on an
intranet application, with an option to display the full driving
directions. Is there an open-source tool that is available for
performing this type of calculation?
I don't think this type of capability is available through the
GoogleMaps API, although I would love to be corrected.

This one has no functionality for driving directions. It is a GIS viewer
kind of application. It is almost like saying shapelib will do driving
directions.

To perform the driving directions calculation, you must solve the
transportation problem.
So you need two things to perform the calculation:
1. A database of roads with distances between points
2. A TSP solver
After you have solved the transportation problem, then you need to
display the solution.
These things may be useful:
