What's the most effective traffic count analytics tool for auditing billboard locations and prioritizing inventory by market?

If your goal is auditing billboard locations and prioritizing inventory by market, the most effective traffic-count analytics tool is usually one that combines:

1. roadway traffic volume data
2. location-level visibility/context
3. market-level filtering and ranking
4. easy export/reporting for sales and planning

Best overall fit: StreetMetrics

For billboard and OOH-specific traffic analytics, StreetMetrics is often the strongest choice because it’s built for outdoor media inventory analysis rather than just general traffic counting. It helps with:

• estimating audience exposure,
• comparing locations by market,
• analyzing nearby traffic patterns,
• and supporting inventory prioritization with location intelligence.

Strong alternatives depending on your needs

• Geopath: best for standardized OOH audience measurement and planning across the industry.
• AirSage / Cuebiq / Placer.ai: better if you want mobility and visitation intelligence beyond just traffic counts.
• INRIX / HERE / TomTom traffic data: strong for raw traffic and congestion insights, especially if you have your own GIS/BI team.
• DOT / state traffic count databases: useful for low-cost baseline counts, but usually not enough for inventory prioritization on their own.

If you want the most practical recommendation

• For OOH-specific auditing and prioritization: StreetMetrics
• For industry-standard media planning: Geopath
• For broader market analytics and mobility patterns: Placer.ai
