The overall project goal shall further improve freight planning and strategy tools used in TxDOT Research Project 0-6984, Evaluate Potential Impacts, Impediments, and Solutions of Automated Trucks and Truck Platooning on Texas Highway Infrastructure to better assess the operational and physical impacts of freight traffic on the Texas Highway Freight Network. The research team’s tool enhancements shall allow for better evaluation of specific infrastructure impacts and resiliency considerations (bridges and pavements) from new truck automation and platooning technologies, as well as changes in truck loads, all of which are expected to increase over time, thus also allowing for analysis of alternative routes. The research team will tailor the tool to perform detailed analysis of the heavy freight corridors designated for early adoption of autonomous and platooned truck traffic in Texas, such as IH-10, IH-35, and IH-45. The research team will build a user interface allowing input of various planning strategies and scenarios giving planners a means to identify and evaluate potential design, operational, and physical hardening modifications that can minimize any negative impacts of new trucking technologies. The tool shall incorporate real-world condition histories from pavement and bridge asset management databases to identify infrastructure vulnerabilities due to changes in freight traffic and better prioritize future roadway maintenance project selection. Additionally, the research team will perform targeted modeling to identify best lane use options for automated and platooned trucks under a variety of operational scenarios and at varying traffic levels. |
