Foot Traffic Analysis
The measurement and interpretation of pedestrian and vehicle flow around a commercial location.

Definition
Foot traffic analysis is the measurement and interpretation of pedestrian — and sometimes vehicular — volume around a commercial location. It quantifies how many people pass by, when they peak, where they come from and how that flow translates into store visits and revenue.
It is the single most important quantitative input to site selection: a great operator in low-traffic location loses; a mediocre operator in high-traffic location often wins.
3 ways to measure foot traffic
1
Physical sensors
Door counters, beam-break sensors and overhead cameras at the entrance. Highly accurate inside the store but no view of who walked past.
2
Mobile location panels
Aggregated, anonymized smartphone GPS data (Placer.ai, SafeGraph). Granular visit data but expensive ($5k+/yr) and strongest in the US.
3
Google Maps + AI modeling
Popular-times signals from Google Maps combined with demand modeling. Directionally reliable, global coverage, on-demand at $99/report (WhereToOpen.ai approach).
Benchmark by business format
| Format | Healthy daily passers-by | Conversion rate |
|---|---|---|
| High-street retail | 8,000–15,000 | 2–4% |
| Coffee shop | 1,500–3,000 | 5–10% |
| Restaurant | 500–1,500 | 3–6% (lunch/dinner) |
| Gym | N/A — destination | Catchment-driven |
| Pharmacy | 2,000–5,000 | 8–15% |
Measurement technology in detail
Each measurement approach carries different accuracy, coverage and cost trade-offs. Picking the right one depends on whether you need real-time in-store signal or pre-lease decision support.
Door counters & beam sensors
Accuracy 95%+ inside the store, but tells you nothing about who passed by without entering. Cost: $300–$2,000 hardware, ongoing reporting subscription.
Overhead cameras with CV
Anonymized people-counting cameras with computer vision. Higher accuracy than beams; can segment groups, dwell time and demographics. Cost: $1,500–$5,000 per door + monthly SaaS.
Mobile-device panels
Aggregated, anonymized GPS data from opted-in mobile-app SDKs (Placer.ai, SafeGraph). Granular trip-level data, but US-centric and expensive ($5k–$50k/yr).
Wi-Fi probe analytics
MAC-address sniffing of nearby smartphones. Privacy-sensitive, declining accuracy as iOS/Android randomize MAC addresses.
Google Maps + AI modeling
Popular-times curves from Google Maps blended with AI demand modeling per business format. Directionally accurate, global coverage, available on demand at $99/report.
Seasonality factors that distort foot traffic
A single-day or single-week measurement is dangerous. Healthy foot-traffic analysis adjusts for these seasonal effects before drawing conclusions.
- Tourism cycle: Mediterranean cities can see 3–5x summer-vs-winter swings.
- Weather sensitivity: Outdoor terraces and pedestrian streets can lose 40–60% on rainy weeks.
- Local school calendar: Cafés near schools dip during holiday months.
- Office occupancy: Post-COVID hybrid work has permanently reshaped Monday/Friday foot traffic in CBDs.
- Local events: Concerts, fairs and matches produce one-day spikes that should not be averaged into the baseline.

Frequently asked questions
What is foot traffic analysis?
Foot traffic analysis is the measurement and interpretation of pedestrian (and sometimes vehicular) volume around a commercial location. It quantifies how many people pass by, when they peak, where they come from and how that translates into store visits and revenue.
How is foot traffic measured?
Three main methods: (1) physical sensors and counters at the entrance, (2) mobile-location panels (Placer.ai, SafeGraph) that aggregate anonymized smartphone data, and (3) Google Maps popular-times signals combined with AI demand modeling — used by WhereToOpen.ai for global, on-demand analysis.
Why is foot traffic important?
Foot traffic is the leading indicator of revenue potential for any brick-and-mortar business. Higher visible foot traffic typically means more impressions, more walk-ins, and lower customer acquisition cost. It also helps validate rent — high-traffic addresses justify higher rent only if your conversion rate fits the format.
What's a good foot traffic number?
It depends on the format. A prime high-street retail location might see 10,000+ pedestrians per day; a successful neighborhood coffee shop needs 1,500–3,000; a destination restaurant can thrive on 500–1,000 highly-targeted passers-by. Industry benchmarks always beat absolute numbers.
How accurate is AI-based foot traffic data?
Accuracy depends on the source. Mobile-panel data (Placer.ai) is granular but expensive and US-centric. Google Maps + AI modeling (WhereToOpen.ai) is directionally reliable and works globally for go/no-go decisions at $99 per address.
