CASE STUDY: COAST-TO-COAST ROUTE

LA to NYC: How Many Impressions?

A common question from fleet owners and advertisers: if a 53' trailer carrying a 27'×8' side billboard drives from Los Angeles to New York City, how many gross impressions does that trip actually generate? Here's the math.

Methodology

How We Build the Estimate

The same traffic-count approach used across the Out-of-Home industry (similar to Geopath circulation methodology), applied to a moving trailer instead of a fixed billboard.

1. Map the Route

Break the trip into highway legs: LA → Phoenix → Albuquerque → Amarillo → OKC → Memphis → Nashville → Knoxville → Harrisburg → NYC.

2. Pull Traffic Volume

Apply typical Average Annual Daily Traffic (AADT) counts for each highway segment — these range from ~20,000 on rural stretches to 100,000+ near major metros.

3. Weight by Time on Road

Longer legs driven at a ~500 mi/day pace carry more weight, since the trailer spends more exposure time on that traffic volume.

4. Sum the Legs

Add every leg's contribution together to get total gross impressions for the one-way trip.

Route Breakdown

Southern corridor: I-10 → I-40 → I-81 → I-78, the most common legal routing for 53' trailers coast to coast.

The Short Version

Average Daily Impressions × Transit Days = Gross Impressions. At BillAdz's typical 40,000–60,000 daily impressions, a ~5.5 day coast-to-coast run lands right around 250,000–300,000 gross impressions one-way — and roughly double that for a round trip.

A Few Honest Caveats

This is a modeled estimate based on typical public traffic-count data, not a live measurement. Actual circulation shifts with the exact route taken, time of year, construction detours, and whether the trailer runs day or night. For a real campaign, we track actual GPS mileage and the specific highways driven to build a route-accurate impressions report — not just a corridor average.
