Here is the uncomfortable question that follows every city centre event budget: the Saturday market felt busy, the photos looked great, and the retailers on the square said it was a good day. But the shops two hundred metres down the street reported nothing unusual, and the property owner you asked to co fund next year wants a number, not an anecdote. Most event managers cannot answer with data because the measurement was never in place before the event happened.
Pedestrian counting in city centres is the continuous, automated measurement of how many people pass defined points on streets and squares, typically using overhead sensors that record counts and direction without identifying anyone. It produces hourly, daily and seasonal footfall data that can be compared across street sections and against previous periods, which is what makes event impact measurable rather than estimated.
An event that draws five thousand people to a square has not necessarily done anything for the high street. The question retailers actually care about is displacement versus distribution. Did visitors walk past shopfronts on the way in and out, or did they arrive, watch, and leave by the shortest route? Counting by street section answers this. When you place counting points on the square itself and on the approach streets, and the sensors record direction of travel, you can see whether an event pushed traffic along the retail corridor or simply concentrated it in one spot.
Manual counts cannot do this. A clicker survey covers a fraction of the hours, depends on who is holding the clicker, and cannot be repeated the same way next year. Odense and Copenhagen both use accurate pedestrian counting in their shopping streets, and the figures are used specifically to measure events and arrangements. That is the model: permanent counting infrastructure first, events measured against it second.
A practitioner observation that comes up on nearly every municipal project: the single most common mistake is commissioning counting six weeks before the Christmas season and expecting to report on the Christmas market's effect. Without months of normal weekdays and ordinary Saturdays in the data, there is nothing to compare the event against. The uplift you report will be a guess dressed up as a measurement, and the retailers who co fund will notice.
The honest comparison is not event Saturday versus the Friday before. It is event Saturday versus the same weekday in the same season last year, adjusted for weather and school holidays, with the event marked on the same timeline as the footfall curve. A calendar and event module that places markets, campaigns and public holidays directly on the traffic graph makes this a five minute exercise instead of a spreadsheet project. It also protects you from the opposite error: claiming an uplift that was actually just a sunny weekend.
The municipalities furthest along treat footfall as shared infrastructure across departments. Copenhagen, Aarhus and Aalborg use counting across libraries, museums, sports halls, swimming pools, outdoor activity areas, forest paths and playgrounds. Many Danish libraries run it in both staffed and unstaffed locations, tracking visitor numbers, live occupancy and even use of seating. Fredericia Idraetscenter uses visitor counting to understand flow to individual activities and to plan staffing. For a city centre manager, this matters because the same platform that measures your Saturday market can answer whether the new playground changed movement patterns toward the shopping street. One dataset, many budget conversations.
GDPR is usually the first question from the legal department, and the answer is straightforward when the technology counts without any personal identification. No cameras storing faces, no phone tracking, just counts, directions and dwell patterns.
How accurate is outdoor pedestrian counting? Vemco contractually guarantees a minimum of 96 percent accuracy, and in practice results typically reach 98 to 99 percent where conditions such as lighting, mounting position and visitor behaviour allow. Treat the guaranteed figure as the floor, not a marketing headline.
How long before an event season should counting be running? Ideally twelve months, so every event can be compared against the same weekday last year. If that is not possible, several months of baseline is still far better than none, but be transparent about the limitation in your first report.
Can we compare different parts of the high street? Yes. Counting by street section is the core method for showing whether an event distributed traffic along the retail corridor or concentrated it in one place, and direction of travel shows which way people moved.
Does this lock us into one sensor brand? No. Vemco's platform has integrated with more than 40 sensor manufacturer types since 2005, and the company is a Xovis Gold partner, so hardware choices can follow the site conditions rather than the software.
Vemco Group is a Danish company founded in 2005, headquartered in Fredericia with offices in Sweden, Brazil, Canada, Australia, the UAE and Saudi Arabia, with over 55,000 installations in more than 98 countries and Danish support behind the platform. If you are planning next year's event calendar and want the baseline in place before the first market opens, contact Vemco to discuss counting points, baseline timing and what an event impact report for your high street should contain.
