The Importance of Highways to U.S. Agriculture Appendix B: Analysis Corridor Condition, Performance, and Commodity Flow Data Visualizations B-3

Analysis Corridor Condition, Performance, and 

Commodity Flow Data Visualizations

This appendix visualizes conditions, performance, and commodity flow data for each of the 17 analysis corridors presented 

in the report The Importance of Highways to U.S. Agriculture. The report draws from these data to inform the analysis and 

narratives included in Section 4: Agricultural Freight Flows and Performance.

This appendix will help readers: 

• Visualize key information about the condition and performance of the 17 analysis corridors;

• Understand in greater detail how agricultural commodities move along the corridors; and

• Identify performance challenges affecting the movement of agricultural commodities along the corridors.

Approach

This report uses a novel approach to combining agricultural commodity flow, infrastructure condition, and highway performance 

data to analyze corridor performance for domestic agricultural freight. This appendix visualizes these data using linearlyreferenced strip charts and corridor context maps which allow readers to quickly see information from multiple datasets for each 

location along the analysis corridors.

This approach demonstrates the potential for using highway conditions and performance data to better understand how 

highway infrastructure and performance affects agricultural freight movements. Transportation agencies may consider a similar 

approach to conduct their own corridor analyses using this appendix as an example. With the exception of the agricultural 

commodity data from IHS Markit’s Transearch database, all datasets used are available to State Departments of Transportation 

from the U.S. Department of Transportation. For details about the methodology used to develop the data presented in this 

appendix, see Appendix C: Methodology.

How to Read these Visualizations

Data for each corridor is presented alongside a context map describing the route, mileage, major cities and urbanized areas 

along the corridor. Nearby agricultural processing centers and intermodal transfer locations are also included in the maps for 

context. 

Strip charts below the context maps visualize data from various sources and are linearly-referenced to the mile markers shown 

in the maps. Some strip charts contain two lines of data, showing information for both directions of travel. 
The Importance of Highways to U.S. Agriculture Appendix B: Analysis Corridor Condition, Performance, and Commodity Flow Data Visualizations B-4

Conditions and Performance Data

The first page of each corridor includes strip charts showing data about the physical infrastructure conditions and performance 

of the corridor. Highway segments with Travel Time Index (TTI) > 1.2 or Truck Travel Time Reliability (TTTR) > 2.0 are also shown 

as the shaded areas across all datasets to help readers identify areas with congestion and reliability performance challenges on 

the agricultural commodity flow strip charts on the commodity flow data pages.

Figure 1 below shows an example visualization. See Table 1 for additional details.

6 TTI Travel Time Index

Describes the ratio of peak congestion to free 

flow traffic where 1 is free flow traffic during peak 

congestion, and a higher value indicates longer 

travel times. For example, a TTI of 1.25 would 

indicate that travel time during peak congestion 

would take about 25% longer than in free flow 

traffic.

Commodity Flow Data 

The second, third, and fourth page of each corridor present 2018 data describing domestic agricultural freight tonnage, market 

value, and truck unit data from the IHS Markit Transearch database, for the focus commodities traveling in significant quantities 

across that corridor (Table 2). Highway segments with TTI > 1.2 or TTTR > 2.0 are also overlaid on agricultural commodity data 

strip charts to help readers identify performance challenges that affect movement of specific commodities.

Context Map 

Each page contains a context map of the corridor. The maps are oriented so that the corridor is horizontal on the page (as 

opposed to north arrow facing upward) to help the reader more directly reference the strip chart data to locations on the
