It is specifically designed as an adjunct to SIDRA, although the software will run a fully functional vehicle driver model, albeit with a limitation on the number of links and zones that can be used.

This version of the suite TRACKS_LITE has been cut down to include only those programs needed for a conventional three step model. It has been developed specifically to support the link with SIDRA as a low-cost means of integrating the ability of TRACKS to forecast flows with the power of the intersection analysis capabilities of SIDRA.
