Customer story — Lugdunum archaeological site

Background of the project

The archaeological site of Lugdunum, classified and subject to strict heritage constraints (UNESCO, DRAC), has a major particularity: Access is free, no ticket office required.

Until recently, attendance was based solely on estimates, with no reliable tool to measure flows over the year.

Several solutions have been considered:

• manual counts,
• mobile tracking solutions (not adapted to network coverage),
• heavy devices (cameras, masts), incompatible with the constraints of the site.

The need was therefore clear: to have a discrete, autonomous, minimally intrusive counting tool without heavy infrastructure, compatible with a sensitive heritage environment.

“Any establishment requires a file with the DRAC. We needed a device that was as least intrusive as possible, removable and without wiring.”

Box — Kiomda service

Kiomda supported the site with supply and commissioning of several meters, installed from August 2024 on various accesses of the site.

The solution was chosen to:

• her lightness of installation,
• its lack of heavy infrastructure,
• her low dependence on the mobile network,
• its good relevance/price ratio.

“Kiomda was the most coherent solution between the proposal and the price. The others were either too heavy or unsuitable.”

The data is accessible via the Kiomda platform and exported to feed internal analyses and territorial tools (in particular the metropolitan platform).

Testimonial — uses and exploitation of data

Since the establishment of the counters, the site has benefited from a structured and regular attendance monitoring :

• monthly reports (attendance, access, time slots),
• analysis of peak attendance,
• consolidated annual balance sheets.

“Every month, I assess attendance: number of visitors, accesses, time slots. We have a really interesting analysis.”

The data made it possible to correct major estimation biases.

“We thought we would have 850,000 visitors per year. In reality, we are more than double that.”

Beyond the volume, they revealed a unexpected diversity of uses :

• heritage visitors,
• daily users (walks, sports, dogs),
• non-tourist attendance.

“There are a lot of uses other than what we imagined.”

The data today is:

• shared with museum teams,
• followed by management and CODIR,
• cross-referenced with qualitative surveys (tourism students).

They also feed into territorial devices, such as the platform OnlyLyon/CityTrend, allowing reuse on a metropolitan scale.

Observed benefits

The benefits are multiple and concrete:

Operational

• adjustment of supplies (sanitary facilities, equipment),
• better management of flows on the site.

“Stupid thing, we had 850,000 visitors per year according to our estimates. With this figure we quantified the soap and toilet paper we buy, we were in short supply all the time. In the end we have more than double the number of visitors..”

Strategic

• identification of accesses to be enhanced (signage, facilities),
• questioning the initial hypotheses,
• management informed by real data.

Organizational

• sharing data internally,
• increase in collective competence on attendance issues.

“It allows you to rethink a certain number of prejudices that we may have had.”

Overall assessment and areas for improvement

The Kiomda solution is considered very satisfactory, with a score of 9/10.

“The efficiency of the sensors is very good, the platform too, and the after-sales service is responsive. In terms of form, I couldn't find anything better: the least intrusive product possible.”
