The Texas DOT long-range transportation plan used TREDIS to evaluate user benefits and broader economic conditions in 2050 under alternative transportation futures. In addition to standard highway distance, time, and reliability, the analysis included bridge detour modeling, pavement condition modeling, crash frequency modeling, and labor market accessibility for Texas’s largest metropolitan areas.

To evaluate a range of policy goals, the analysis integrated the TREDIS economic model with a spreadsheet reallocation of crash costs connected to IMPLAN modeling, a pavement condition analysis, travel modeling of bridge detour VMT effects, and labor market accessibility calculated from a travel model. The results evaluated economic impacts associated with policy scenarios shown below.
