Freight Mobility Trends Report 2019

APPENDIX B: MAJOR FREIGHT HIGHWAY BOTTLENECKS AND CONGESTED CORRIDORS—FULL REPORT

Table 35 lists the 2019 top Interstate bottlenecks and congested corridors in the United States based on truck hours of delay per mile for 2019.

Delay per mile (DPM) is calculated for each Interstate segment using the 2019 National Performance Management Research Data Set (NPMRDS) travel time data in the Freight Mobility Trends (FMT) tool in the following manner:

  • Delay is calculated for each 15-minute time period as the difference between actual travel time and reference travel time. Reference travel time is based on 85th percentile speed during off-peak and overnight time periods.
  • Delay for each 15-minute time period is multiplied by 15-minute truck volumes. Truck volumes are estimated from Annual Average Daily Truck Traffic (AADTT) using typical time-of-day traffic volume profiles. Delay for each 15 minute time period is aggregated to get annual truck hours of delay.
  • The total truck hours of delay are then divided by the segment length to get total truck hours of delay per mile, allowing for the comparison of all roadway sections across the National Highway System (NHS).

These locations were then compared with the bottlenecks identified by States in their 2018 Baseline Performance Reports.

Table 35 lists the route, urban area, and State ordered by 2019 truck hours of delay per mile. Information is provided for the directional AADTT, annual truck hours of delay per mile, Planning Time Index (PTI), Buffer Index (BI), Travel Time Index (TTI), Truck Reliability Index (TRI), and total corridor congestion cost per year. Annual truck hours of delay per mile is determined at the most congested segment of the corridor. Total corridor congestion cost is calculated for the full extent of delay along the congested corridor, which may include multiple segments, as a function of both the time and fuel used while the truck is in congested traffic, factoring costs of personnel, commercial vehicle operation, and wasted fuel. Definitions of these categories and indicators appear after the table, as do maps of the top 40 bottlenecks.

Key: annual average daily traffic (AADT), delay per mile (DPM)

Table 35 uses the following definitions, which are the same as those used to develop the results in this report:

  • Generalized bottleneck location/ congested corridor and length—the extent of congestion for the corridor caused by one or more bottlenecks, estimated based on review of corridor congestion scans in the NPMRDS. For major congested corridors, this may include multiple contiguous bottlenecks.
  • Annual Average Daily Traffic (AADT) (trucks)—the NPMRDS directional (single unit and combination) trucks conflated from the Highway Performance Monitoring System (HPMS).
  • Annual truck hours of delay/mile—the difference between actual travel time and reference travel time (free-flow travel time), multiplied by truck volumes and then divided by the segment length. For larger bottlenecks that span multiple roadway segments, delay is provided for the most congested segment and direction of the bottleneck, not the full corridor.
  • Planning time index—the ratio of the 95th percentile travel time to the reference travel time (free-flow travel time), computed during the AM and PM peak periods.
  • Buffer index—represents the extra time (or time cushion) that travelers must add to their average travel time when planning trips to ensure on-time arrival.
  • Travel time index—the ratio of the peak-period travel time to the reference travel time (free-flow travel time), computed for the AM and PM peak periods.
  • Travel reliability index—calculated the same as the Moving Ahead for Progress in the 21st Century (MAP-21) performance measure for truck travel time reliability, as the ratio of the 95th percentile travel time to the 50th percentile travel time during five different time periods of the day. Results will differ from the NPMRDS Travel Time Reliability (TTTR) due to differences in route segmentation.
  • Total corridor congestion cost (dollars/ year)—calculated for the full extent of delay along the congested corridor as a function of both the time and fuel used while the truck is in congested traffic, factoring costs of personnel, commercial vehicle operation, and wasted fuel. For major bottlenecks with long congestion queues, this includes multiple roadway segments. For major congested corridors, the congestion cost includes the full cost of congestion along the corridor through the entire urban area, which may include multiple bottlenecks.

Changes between 2018 and 2019 Top 100 Bottlenecks

Based on a comparison of truck hours of delay per mile, the following bottlenecks saw the greatest relative percent change (increase or decrease) in delay between 2018 and 2019. In many cases, major increases in delay from one year to the next can be attributed to major construction projects/work zones along the corridors.

The bottlenecks in table 36 saw the greatest percent increase in delay from 2018.

Based on changes to truck hours of delay per mile, the bottlenecks in table 38 saw a relative increase in delay, moving the locations to the top 100 bottlenecks, or a relative decrease in delay, dropping the locations below the top 100 bottlenecks. The bottlenecks in table 38 were added to the list in 2019.

The bottlenecks from 2018 in table 39 dropped off the list in 2019.
