Abstract:Texas Department of Transportation (TxDOT) Project 0-7037 was initiated to develop a model/tool that could help TxDOT and other transportation planners estimate and assess impacts of changes in freight traffic flow on the Texas Highway Freight Network more quickly than by conducting a full Statewide Analysis Model run. The goal was to produce a tool that could assess proposed change scenarios regarding the introduction of new freight generators or shifting of existing freight facilities/employees to new locations by leveraging the availability of new freight-related economic databases and the use of advanced data analysis methods. Project researchers used several economic databases to determine the estimated number of truck trips for the top 50 industries (by dollars) in Texas and examined statewide county-to-county estimated truck flows based on commodity production and consumption locations. Four analysis modules covering New Firm, Relocate Firm, Warehouse Flow, and Network Closure Scenario impacts were included to advance the model to the minimum viable product (MVP)/Technology Readiness Level 6 stage.
