Wednesday, August 10, 2022

The U.S. Department of Transportation has convened an interagency working group, led by the Bureau of Transportation Statistics, to develop timely information on supply chain activity. The working group includes relevant DOT modes and the U.S. Departments of Agriculture, Energy, Commerce and Labor. 

BTS freight information is organized into four sections:

Port Congestion - Inside the Gate

 

Port Congestion - Outside the Gate

Freight Movement

Notes

These selected measures are provisional indicators of transportation activity and have not been reviewed for representativeness or other aspects of statistical quality. Additional measures will be added as they become available.

  • Containerships Anchored off U.S. Ports: This metric shows the number of container ships within US port boundaries, that are inbound (not outbound), that have automatic identification system (AIS) status "anchored" and are not moored/birthed. This metric is a snapshot; the vessels are counted using AIS live by U.S. Maritime Administration (MARAD) on Tuesday afternoons.
  • Containerized Imports and Exports: Includes data for all U.S. container ports. Data subject to revision due to data source gaps.
  • Containerships Awaiting Berths: LA-LB totals include containerships in drift/holding areas. Data reported at more frequent intervals starting October 18, 2021.
  • Rail Carloads and Intermodal: U.S. traffic excludes the U.S. operations of Canadian and Mexican railroads.
  • Job Openings and Labor Turnover: Data in this chart represent wage and salary workers only and exclude owner operators and independent contractors.
  • Truck Spot Rates: This data is for spot market trucking loads, which is approximately one-tenth of the overall common carrier trucking market. The data provider (DAT) is the largest clearinghouse for shipments that are not part of a pre-existing hauling contract. Dry van includes freight transported in enclosed cargo holds.
  • NHS Weekday Peak Hour Travel Time Median Speed (mph): The chart shows National Highway System roadways and Urban Interstate Highways weekday freight truck median speed compared to speed for the same month of previous years. Source: Federal Highway Administration, National Performance Management Research Data Set.
  • LA/LB and NY Port Area Reliability - Average Truck Speed on the National Highway System Within 5 Miles of Port (mph) and Planning Time Index on the National Highway System Within 5 Miles of Port: Planning Time Index (PTI): Ratio of 95th percentile truck speeds and free-flow truck speeds within five miles of port. Average Truck Speeds on the National Highway System within five miles of port. Source: Federal Highway Administration, National Performance Management Research Data Set.
  • Average Weekday Truck Speed at Interstate Bottlenecks Locations (mph) and Planning Time Index at Interstate Bottleneck Locations: Planning Time Index (PTI): Ratio of 95th percentile truck speeds and free-flow truck speeds. Source: Federal Highway Administration, National Performance Management Research Data Set.
  • Interstate Vehicle Miles Traveled (% change from 2019): The Weekly Traffic Volume Report estimates the vehicle miles traveled (VMT) for interstate highways and how the total travel measured by VMT compares with travel that occurred in the same week of 2019. The VMT is further split into passenger vehicle and truck components. Estimates and preliminary. Refined estimates are with FHWA’s Monthly Traffic Volume Trend Report; Final data are provided through FHWA’s Highway Performance Monitoring System. Data sources used for all VMT modeling estimates are based on permanently installed traffic monitoring roadway sensors and other passive data observations.
  • Month-to-Month Change in Employment - Truck Transportation Employees on Non-Farm Payroll (Seasonally Adjusted): Data in this chart represents wage and salary workers only, and excludes owner-operators and independent contractors. Source: Bureau of Labor Statistics, Current Employment Statistics
  • Job Openings and Labor Turnover: Transportation, Warehousing, and Utilities Sector (Seasonally Adjusted): Monthly job openings, hires, and separations (includes Quits, Layoffs, Other Separations) for Transportation, Warehousing, and Utilities (which includes Truck Transportation). When hires exceed separations, the industry experiences job growth, and Quits are a measure of employees' willingness to leave a job (e.g., generally as the economy improves). Data in this chart represents wage and salary workers only and excludes owner-operators and independent contractors.
  • Producer Price Index (PPI): PPI data are survey data collected monthly and indexed to 12/2003=100. Respondents provide data on Tuesday of the week containing the 13th of the month.
  • Ocean Freight Rates: Spot ocean freight rates for a single container transaction in the selected westbound transpacific trade routes.
  • Inventory-to-Sales Ratio: The ratio of total inventory at retailers, wholesalers, and manufacturers, divided by total sales. Data on inventory and sales are based on Census Bureau surveys. Data adjusted for seasonal, holiday and trading day differences but not for price changes.
  • Freight Transportation Service Index: Economically weighted volume of freight and passenger transportation services moved by the for-hire transportation sector in the U.S.
  • U.S. Diesel Sales Prices: Weighted average based on sampling of approximately 350 retail outlets, as reported for the week ending Monday.
