Promiles

Daily retail diesel price observations at over 5,500 named truck stops nationwide, refreshed every 24 hours and geolocated so prices tie to the specific lane a load travels — a station-level daily price panel the public DOE/EIA series (a weekly national average from roughly 350 outlets) cannot provide. Surrounding byproduct assets: computed lane, radius and interstate surcharge rates together with the MPG, trigger-point and cost-per-gallon adjustment parameters used, plus audit records evidencing the fuel cost actually applied at the time of each shipment.

Dataset card

Type: not stated
Format: Tabular time series — station x date x price, with derived lane-level surcharge tables; delivered through a web application with lane/radius/interstate calculators (no open download or public API indicated on the page)
Volume: est. ~2 million price observations per year (5,500 truck stops x 365 daily refreshes), roughly 4,000 rows per day and only a few MB per year raw — small in bytes, very high in economic content, with an archive likely spanning many years. The derived lane-level surcharge layer multiplies this by active lane count, and per-load audit records add one row per audited shipment.
Users: est. low thousands of shipper and carrier organizations using the surcharge index alongside ProMiles' routing products — the index is positioned as an industry-wide shipper/carrier collaboration rather than a single-firm utility (inferred from ~130 employees, ~$18M revenue and the North American trucking buyer base)
History: 15 years
Update frequency: not stated
Growth: Active — the product page carries 2025-dated site assets and the index is marketed as a live daily-updated service, with the surrounding ProMiles routing and mileage product line still actively sold
Launched: est. 2010s for the Fuel Surcharge Index, layered on a ProMiles routing-software business that has operated for decades. The DOE-based surcharge practice it positions itself against dates to the mid-1970s OPEC era, which the page recounts explicitly — the station-level alternative is a far more recent construction.
