HEALTH OF THE U.S. SUPPLY CHAIN
Drayage index The drayage activity index measures weekday truck entries at the San Pedro Bay Ports (Los Angeles and Long Beach) and the Port of New York and New Jersey (Port Newark- Elizabeth, Port Liberty Bayonne and Howland Hook Marine Terminal, treated as one combined zone), normalized against the local trucking population. An entry is counted as a weekday truck-trip that starts outside and ends inside the port zone. The fleet base, which is used for normalization, is the count of distinct trucks with at least one trip ending in the port’s home or surrounding counties. The index itself is entries per working day per 1,000 fleet-base trucks, indexed to baseline Q4 2025 = 100. City analysis City metrics cover Door-to-Door delivery vehicles, vans, small trucks, and cars, operating inside four representative cities, each defined by its municipal boundary. • Trip inclusion. A trip is counted if its origin or destination falls inside the city. • Distance filter. Only trips longer than 0.1 miles are included. Penetration Penetration is defined differently for the two analyses. • Corridor penetration answers what share of Geotab’s fleet used these corridors. VMT % is the corridor-linked journey mileage divided by the mileage for all trucks of the same vocation anywhere in the U.S.; Vehicle % is the
limits. Weekend activity is excluded because the vocations studied operate predominantly on weekdays. These insights are based on aggregate historical data and are provided for informational purposes only. They do not constitute, and should not be relied upon as, economic, operational, or business advice.
count of distinct trucks that ran at least one qualifying corridor journey divided by all trucks of that vocation that ran a qualifying journey anywhere in the U.S. The 50–1,000 mile cap is applied identically to both sides of each ratio. • City penetration answers what share of a city’s tracked commercial vehicle activity is Door-to-Door. Miles Share % is Door-to-Door trip miles inside the city divided by trip miles for all classified vocations combined inside the city; Vehicle share % is distinct Door-to-Door vehicles divided by all Geotab classified vehicles in the city. Why median for corridors and average for cities Corridor journey distances are bounded (capped at 50–1,000 miles) and roughly symmetric, so the median gives a stable, representative picture of a typical freight run and underpins the estimated-speed calculation. City Door-to-Door trips are highly skewed because there are so many very short trips that the median understates real activity. We therefore report the average for cities, which reflects total delivery mileage and aligns with the mileage-based penetration figures. Coverage and limitations Geotab’s network represents vehicles enrolled on its platform, a large, representative sample of U.S. commercial activity, not a census. Vocation assignments are model- based and may not perfectly match every vehicle’s business purpose. Cross-boundary trips are included by design, so city mileage includes some distance driven outside the city
