(1) The department shall use the transportation demand modeling tools developed under subsection (2) of this section to evaluate investments based on the best mode or improvement, or mix of modes and improvements, to meet current and future long-term demand within a corridor or system for the lowest cost. The end result of these demand modeling tools is to provide a cost-benefit analysis by which the department can determine the relative mobility improvement and congestion relief each mode or improvement under consideration will provide and the relative investment each mode or improvement under consideration will need to achieve that relief.

(2) The department will participate in the refinement, enhancement, and application of existing transportation demand modeling tools to be used to evaluate investments. This participation and use of transportation demand modeling tools will be phased in.
