Key points
  • The ROI of a meter is not measured in turnover but in the ability to make informed decisions and to attract financing.
  • Attendance data is often required in grant applications (AVELO, CRTE, European funds).
  • A meter makes it possible to avoid costly investment mistakes by objectifying the real needs before any development.
  • The before-and-after measurement is the only credible way to demonstrate the impact of a project to funders and citizens.
  • The cost of a metering network (a few thousand euros) is negligible compared to the development budgets that it makes it possible to secure.
  • The real cost is the absence of data: decisions based on estimates, poorly sized projects, fragile justifications.

1. Why does the concept of ROI apply to territorial counting

Return on investment is a concept usually associated with private companies: how much is the return on investment for each euro invested? For a territorial authority, the logic is different. Public investment does not aim to generate profit, but to improve the quality of public service, to meet the needs of users and to manage territorial policies effectively.

In this context, the ROI of a transit counter is not calculated in terms of turnover generated, but in terms of value created for decision making. This value can take several forms: the ability to obtain grants that would not have been accessible without data, savings achieved by avoiding the over-sizing of infrastructure, strengthened credibility with funders and citizens, or even optimization of future investments thanks to a better understanding of real uses.

Presenting the purchase of meters as an “expense” is a framing error. It is an investment in a management tool that reduces uncertainty and increases the probability of success of development projects. Just like a design office or a project management mission, counting produces information that has a strategic value much greater than its acquisition cost.

2. The four types of value generated by attendance data

Élément Explication
Logique du ROI en collectivité Le retour sur investissement ne vise pas à générer du profit, mais à améliorer la qualité du service public, répondre aux besoins des usagers et piloter efficacement les politiques territoriales.
Nature de la valeur créée Le comptage produit une valeur stratégique : accès à des subventions, optimisation des infrastructures, crédibilité auprès des financeurs et meilleure allocation des investissements futurs.
Réduction de l'incertitude Les données de fréquentation permettent de réduire les risques liés aux décisions d’aménagement et d’augmenter la probabilité de succès des projets.
Positionnement stratégique Un compteur n’est pas une dépense, mais un outil de pilotage territorial, comparable à une étude technique ou une mission d’ingénierie.

Value 1: Capture grants and public funding

Many public funding programs — AVELO (bicycle), CRTE (contracts for recovery and ecological transition), European FEDER funds, calls for projects from ADEME or regions — now require attendance data to process applications. Funders want to know how many people are actually using existing infrastructure, and how many are likely to use the infrastructure you are proposing to create.

Without objective data, a grant application is based on estimates. However, the instructors know the difference between an estimate (“we think that 200 cyclists per day will use this route”) and a factual measure (“we counted 150 cyclists per day on the current route, with a growth of 12% per year for the last three years”). The second approach increases the chances of obtaining financing.

A permanent counting network also makes it possible to produce impact assessments after the project has been completed, which reinforces the credibility of the community for the following issues.

Value 2: Avoid costly sizing mistakes

An undersized layout generates saturation problems, conflicts of use and user dissatisfaction. Oversized development mobilizes public funds for underused infrastructure, which is difficult to justify politically and financially.

Counting data makes it possible to size projects as close as possible to real needs. The cost of a network of a few sensors (between 3,000 and 10,000 euros depending on the size) is negligible compared to the cost of oversizing (wider pavement, additional work) or undersizing (resumption of work, conflicts of use to manage). A sizing error can represent several tens of thousands of euros in additional costs or loss of efficiency.

Value 3: Demonstrate the real impact of public policies

Elected officials and technical services need to be able to justify their choices to citizens, political opposition and the media. Saying “we created a bike path because we think it's useful” is weak. Saying “we have measured 300 cyclists per day on average on this route since it opened, an increase of 180% compared to the old route” is unquestionable.

Attendance data also makes it possible to respond to criticisms. When a development is contested (“this greenway is useless to anyone”), the counting figures put an end to the subjective debate. This legitimation function is particularly important in contexts where investments in favour of active mobility (cycling, walking) are still under debate.

Value 4: Optimize future investments and create a territorial memory

A community that has several years of traffic data on its bike paths, trails or public spaces gradually builds a territorial memory. She knows what types of facilities work, which axes are saturated, which periods require reinforcement, which areas are under-frequented despite investments.

This accumulated knowledge becomes a strategic asset. It makes it possible to prioritize future investments, to replicate proven patterns and to avoid reproducing past mistakes.

This capitalization of knowledge also has value in terms of the continuity of public action. The elected officials are changing, the technical teams are evolving, but the data remains.

3. Calculating total cost vs expected benefit: a simple framework

Cost-benefit calculation framework (10-sensor network/5 years)

Cost Items Order of Magnitude (€)
Sensor purchase (10 × €2,000–€3,500) €20,000 – €35,000
Installation (light installation / existing support) €0 – €1,000
Services (maintenance + platform: ~€2500/year × 5 years) €12,500
TOTAL over 5 years €32 500 – €48 500

The expected benefit can be measured on several axes:

  • Grants captured thanks to attendance data: an AVELO or CRTE file can represent several hundreds of thousands of euros in funding. If counting data increases the probability of obtaining financing by 20%, the benefit greatly exceeds the cost of the sensor network.
  • Savings achieved by avoiding oversizing: calibrating a greenway at 3 meters instead of 4 meters can represent 50,000 to 100,000€ in savings on work.
  • Efficiency gains in management: knowing peak attendance makes it possible to optimize maintenance interventions, adapt opening hours or concentrate communication efforts.
Remember: The benefit/cost ratio is largely favorable in the majority of cases. Arbitrage is not “can we afford to invest? but “can we afford to continue investing without objective data? ”

4. Concrete examples of decisions made possible by data

To make the case tangible, here are concrete examples of decisions informed by attendance data:

  • An intermunicipality that measures an average attendance of 400 cyclists per day on a section of greenway can justify the creation of a link to the city center, where a fuzzy estimate would not have convinced.
  • A municipality that notes that 70% of attendance A trail that focuses on weekends can adapt its services (presence of reception staff, opening of sanitary facilities) to optimize the user experience without mobilizing resources all week long.
  • A tourist office that documents a 25% increase in attendance of a site after a communication campaign can demonstrate the ROI of its marketing actions and justify the renewal of the communication budget.
  • A natural park manager who measures excessive use on a sensitive trail can put in place regulations (temporary closure, reorientation to other routes) based on indisputable data.

In all of these cases, the initial investment in counting results in better calibrated decisions, more efficient services and strengthened legitimacy.

5. How to present the file to elected officials: typical structure

Step 1: Contextualize the issue. Recall current or planned development projects and emphasize that their success depends on the quality of diagnosis and follow-up.

Step 2: Identify the current problem. Explain that decisions are now made on the basis of estimates, which generates a risk: over-sizing, under-sizing, difficulty in justifying choices.

Step 3: Present the solution. Describe the metering network envisaged: number of sensors, strategic location, technology selected, methods of exploiting the data.

Step 4: Quantifying the investment. Present the total cost over 5 years in a transparent manner.

Step 5: Demonstrate the expected benefit. Quantifying or qualifying the gains: achievable grants, potential savings, strengthened credibility. Use concrete examples.

Step 6: Propose a pilot phase if necessary. Deploy 3 to 5 sensors on strategic axes for one year to demonstrate value before generalizing.

This approach puts elected officials in a position to make an informed decision, with all the elements to arbitrate.

6. The cost of no data: an angle that is often overlooked

Without counting, decisions are made based on estimates, perceptions, or approximate benchmarks. These methods involve a significant risk of error. An oversized development mobilizes public funds that could have been allocated elsewhere. An undersized layout generates dissatisfaction and requires corrective work afterwards.

Without data, it is difficult to justify a project to a demanding funder. Grant applications based on estimates are less competitive than those based on objective measures.

Without data, it is also difficult to legitimize choices among citizens. Oppositions can always challenge the figures put forward if they are not supported by a reliable measure.

The cost of the absence of data is real: missed opportunities, sizing errors, weakened legitimacy. Investing in counting is an insurance against these risks.

Faced with this cost, investing in a metering network appears to be a form of insurance: a moderate cost that significantly reduces the risk of costly errors.
