Identifying Cost Elements and Communicating the Significance of Transportation Costs Associated with Corn, Soybeans, and Related Agricultural Products
This ongoing study for the USDA Agricultural Marketing Service will identify the transportation delay costs and resulting increases in retail price associated with the US corn and soybean supply chains. This project builds off previous research which identified the cost to the agricultural sector resulting from transportation delays at the US-Mexico border. A transportation cost model is being developed, which will estimate the transportation cost, by mode, associated with step of the soy and corn supply chains. Results from this will be used to develop an online tool to estimate the benefits to soy and corn producers from new transportation projects. The results will also be used to calculate the transportation costs associated with a basket of food products across several US metropolitan areas.
Railroad Economics Analysis, 2006-2017
This ongoing study for the USDA Agricultural Marketing Service will provide information to agricultural rail shippers on the extent to which external market pressures affect railroad service levels. The analysis will review railroad operating statistics since 2006, determine if railroad cost reductions have affected output, and determine if there are any significant revenue and cost differences between railroads.
Develop an Improved SDDOT Construction Cost Index
This ongoing study for the South Dakota DOT will identify current and potential uses for construction cost indices (CCI) for SDDOT and recommend methodologies for calculating, maintaining, and using a CCI for each identified use. The project will also evaluate the level of risk or uncertainty for projections made using the CCI methods, and identify potential improvements that could be made to the South Dakota Construction Cost Index.
NCHRP 11-08 Rights-of-Way
This ongoing study will identify effective statutory means, agency policies, and project delivery procedures to acquire right-of-way (ROW) and to compensate for utility relocations. It will also develop guidance and implementation plans that state departments of transportation and others may use to enhance the effectiveness of their own practices.
This ongoing study assess the future state of transportation conditions in the state of Texas by analyzing pavement quality, bridge quality, urban traffic congestion, rural connectivity, and household transportation costs in a variety of different scenarios ranging from Grade F to Grade B. The study will also examine the opportunity costs and benefits associated with these scenarios along with what it would take to go from the current state of transportation to the desired state.
Impacts of Automated Trucks and Truck Platooning on Texas Highway Infrastructure
This ongoing study will evaluate the potential impacts, benefits, impediments, and solutions of automated trucks and truck platooning on Texas highway infrastructure by calculating different scenarios with and without truck platooning and automated trucks over an extended period of time. This study will also identify potential solutions that may promote the successful introduction of automated trucks and truck platooning on Texas highway infrastructure.
FHWA: Accelerated Project Delivery
This continuous project for FHWA quantifies economic benefits due to accelerated project delivery times. It provides information describing the National Environmental Policy Act (NEPA) and permitting processes and focus on determining the economic benefits of a shortened NEPA process and permitting timeline that can accrue to businesses, transportation agencies, and the public.
Oregon Highway Cost Allocation Study Methodological Review
This ongoing study for the Oregon Department of Transportation (ODOT) is tasked with analyzing the recent Highway Cost Allocation Study (HCAS) conducted by ODOT and determining whether the approach used in Oregon is consistent with state-of-the-practice for cost allocation studies conducted in the U.S.. This study will also determine recommendations for improvements, as well as an estimated level of effort required for such improvements.
The TRENDS model is designed to provide transportation planners, policy makers, and the public with a tool to forecast revenues and expenses for the Texas Department of Transportation (TxDOT) for the period 2010 through 2035 based on a user-defined level of transportation investment. The user, through interactive windows, can control a number of variables related to assumptions regarding statewide transportation needs, population growth rates, fuel efficiency, federal reimbursement rates, inflation rates, taxes, fees, and other elements. The output is a set of tables and graphs showing a forecast of revenues, expenditures, and fund balances for each year of the analysis period based on the user-defined assumptions.
Since the inception of the TRENDS model, there has been a desire to incorporate the ability to estimate the economic impacts of transportation improvements, allowing decision-makers and the public to have a more defined portrayal of the potential economic and performance improvement outcomes associated with investment decisions. TTI is currently working on developing an economic impact model producing economic and mobility results at the MPO level, allowing the “local-option” function of the TRENDS model to be joined with an economic impact assessment tool.

DART Local Area Benefit/Cost Evaluation System
The Dallas Area Rapid Transit (DART) contracted with the Texas A&M Transportation Institute to develop a benefit/cost and economic impact assessment tool. This tool provides prospective DART partners with macro-level estimates of the impacts of potential new transit stations at locations within cities that are not currently part of the DART service area. Specifically, this tool estimates property and sales tax impacts, primary and secondary employment figures, and regional economic activity impacts related to the construction and operation of prospective DART rail and bus rapid transit (BRT) stations.
