3 Objectives Determine truck vehicle miles traveled (VMT) associated with processed beef and related industries in southwest Kansas. Understand the models used to estimate the pavement damage costs. Understand the limitations of current models used to estimate the pavement damage costs.

4 Introduction Kansas is one of the leaders in meat production in the United States. Traditionally, processed meat, meat byproducts, grain, and other related products are transported primarily using heavy trucks. The industries will continue to grow and there will be more trucks on highways transporting meat and meat-related products.

5 Project Goal To estimate the pavement damage cost attributed to the truck traffic associated with the processed meat and related industries in southwest Kansas.

6 Project Scope US Highway 50/400 between Garden City and Dodge City in Kansas (41.13 miles) 24 counties in southwest Kansas

7 Benefits Select cost-effective transportation modes for the meat processing and related industries Assess highway maintenance needs and set up maintenance priorities Determine reasonable user costs

8 Data Collection Truck Characteristics and Type Pavement Characteristics Data Pavement Maintenance Cost Data

16 Truck VMT Associated with Processed Meat & Related Industries

17 Travel path estimation assumptions  A county centroid o Aggregation of the feed yards o Must be located on a highway  TransCAD travel path analysis o Least distance and cost criteria o Giving priority to the state highway system which provides better serviceability

20 Highway Damage Cost Analysis

21 Studied Highway Section (41.13 miles) Projected Annual Pavement Damage Costs Associated with Processed Meat and Related Industries on the Studied Highway Section (41.13 miles)

22 Highway Damage Cost Analysis Major Highways (1,835 miles) in southwest Kansas Projected Annual Pavement Damage Costs Associated with Processed Meat and Related Industries on the Major Highways (1,835 miles) in southwest Kansas

23 Conclusions For the studied highway section (41.13 miles), the total annual highway damage cost associated with processed meat industries was estimated at $71,019, or $1,727 per mile. The annual damage cost per truck per mile was approximately $0.02.

24 Conclusions If the same truck traffic presented on all major highways in southwest Kansas (approximately 1,835 miles), the total annual damage costs attributed to processed meat and related industries would be $3,169,045.

25 Limitations Truck traffic may be underestimated Truck travel routes may not be accurate Inflation adjustment for pavement maintenance costs may be lower than actual numbers
