Enhancing mobility of people and goods in rural America. Agricultural Analysis 22 Crop Production Elevator & Plant Demands Known Truck Trips and Routes Predict Segment Specific Traffic Estimate Data: Crop Production (NASS), Elevator Volumes (NDPSC), In-State Processors (Survey), Road Network (NDDOT-GIS Hub), Local Road Data (2008 Survey)

Enhancing mobility of people and goods in rural America. Distribution Model 24 Each township connected to nearest 150 elevators Elevators connected to each other Elevators connected to plants Fastest and shortest route algorithms Objective: meet the demands at elevators and in- state processing plants with minimal hauling distances (trucking cost)

Enhancing mobility of people and goods in rural America. Network Optimization Constrained Optimization Model Freshwater to Wells Sand to Wells Gravel to Wells Pipe to Wells Equipment to Wells Supplies to Wells Agricultural Commodities to Elevators and Processors Wheat Soybeans Corn Lentils/Dry Edible Beans Barley Oats Sunflower
26
Enhancing mobility of people and goods in rural America. Network Optimization Thirteen separate optimization models were estimated for each year of the analysis (260 in total) Volumes from all optimization runs were aggregated to individual roadway segments
27
Enhancing mobility of people and goods in rural America. Existing Structure Surface Type obtained from GIS Shapefiles Surface Type verified by county officials Independent verification Graded roadway width – survey
28
Enhancing mobility of people and goods in rural America. Existing Condition 1,000 miles of paved CMC roads were scored using the NDDOT deduct scoring system The approximately 4,500 remaining paved CMC roads were given condition ratings by county officials using a 5 category condition assessment Both condition assessment methods were converted to Present Serviceability Rating (PSR) scores
29
Enhancing mobility of people and goods in rural America. PSRDESCRIPTION 4.0- 5.0 Only new (or nearly new) superior pavements are likely to be smooth enough and distress free (sufficiently free of cracks and patches) to qualify for this category. Most pavements constructed or resurfaced during the data year would normally be rated in this category. 3.0 - 4.0 Pavements in this category, although not quite as smooth as those described above, give a first-class ride and exhibit few, if any, visible signs of surface deterioration. Flexible pavements may be beginning to show evidence of rutting and fine random cracks. Rigid pavements may be beginning to show evidence of slight surface deterioration, such as minor cracking and spalls. 2.0 - 3.0 The riding qualities of pavements in this category are noticeably inferior to those of the new pavements and may be barely tolerable for high-speed traffic. Surface defects of flexible pavements may include rutting, map cracking, and extensive patching. Rigid pavements may have a few joint fractures, faulting and/or cracking and some pumping. 1.0 - 2.0 Pavements have deteriorated to such an extent that they affect the speed of free-flow traffic. Flexible pavement may have large potholes and deep cracks. Distress includes raveling, cracking, and rutting and occurs over 50 percent or more of the surface. Rigid pavement distress includes joint spalling, faulting, patching, cracking, and scaling and may include pumping and faulting. 0.0 - 1.0 Pavements are in extremely deteriorated conditions. The facility is passable only at reduced speed and considerable ride discomfort. Large potholes and deep cracks exist. Distress occurs over 75 percent or more of the surface.
