How Many People See a Wrapped Vehicle? A Michigan-Based Way to Estimate
What independent research says about OOH visibility
- A major Nielsen/OAAA study found 64% of U.S. adults noticed a wrapped vehicle in the past month, and 44% noticed one in the past week—evidence that moving OOH is routinely seen in the wild.
- Broader OOH studies continue to show high roadway exposure (e.g., Morning Consult/OAAA, 2023).
Build an impressions estimate with Michigan data (no fluff)
Use MDOT traffic volumes (AADT) to anchor your forecast:
- Find routes: Note the roads your vehicle drives most (commutes, service areas).
- Pull AADT: Open the MDOT AADT Map (and/or 2023 dataset) and record daily volumes for key segments.
- Apply a conservative visibility factor: Not everyone on that road sees your message. Start with 10–20% of AADT for a moving, side-panel message in mixed traffic (conservative filter for direction, lane position, occlusion, and attention).
- Sum segments × days: Impressions/day ≈ Σ( AADT_segment × visibility% ).
- Seasonality & mix: Heavier in summer corridors and urban cores; lighter on low-density routes. MDOT notes short vs. continuous counts; your estimate improves as you refine routes. Michigan.gov
Example (simple):
- Grand Rapids arterial (AADT 25,000) + Detroit arterial (AADT 35,000)
- Visibility factor 15% (0.15)
- Daily impressions ≈ (25,000 + 35,000) × 0.15 = 9,000/day
- 250 workdays ≈ 2.25 million impressions/year (before frequency/recall adjustments)
Why this method is better than generic “30–70k per day” claims
That common range appears across vendor sites but often lacks local road data. Using MDOT AADT and your real routes keeps estimates transparent and defensible.
Turn exposure into design choices (tie-back to Post #1)
If a route includes higher speeds or longer sight lines, increase letter height (e.g., target readability at 300–400 ft). The 1 inch per 30 ft ratio is a practical starting point for phone numbers/URLs at distance. MUTCD
Compliance note for commercial vehicles
If you operate under USDOT, markings must appear on both sides, contrast with the background, and be legible from 50 feet while stationary. There’s no fixed inch-height in the law, so design for distance and contrast.
How to compare cost vs. other channels (a simple CPM frame)
Lifetime = years in service × annual impressions (from your AADT model).
Pair this with Nielsen/OAAA visibility data to explain why even conservative models produce strong CPMs for service businesses that drive daily.
All-in wrap cost ÷ total lifetime impressions = effective CPM.
