Research and Technology Implementation OfficeUS Transportation CollectionThe researchers took a commodity-based approach to evaluate the value of a list of selected commodities moved on the Texas freight network. This approach takes advantage of commodity-specific data sources and modeling processes. It provides a unique way of performing commodity flow estimation and offers more disaggregated modeling results. The estimated value of commodities can be used to support infrastructure investment decision-making. The researchers also evaluated the impact of seasonal variation and congestion on commodity flow movements
