SAMRoute: A safety breakeven threshold of one day
Compare the safety breakeven threshold of our in-silico preliminary diagnosis to traditional or semi-automated confirmatory on-site diagnostics.
SAMRoute is a pre-diagnostic solution that
assesses risks impacting transportation infrastructure. Its
pre-diagnostics are 100% in-silico, drastically reducing
costs compared to traditional methods such as on-site
inspections.
Using the ROI calculator on this page, we compare SAMRoute to other diagnostic methods. We quantify the minimal gain required for each diagnostic to achieve what we call safety breakeven.
The calculator is structured around three groups of variables.

- Section A gathers assumptions and the characteristics of the infrastructure being analyzed.
- Section B covers variables specific to SAMRoute.

Accelerated ROI with SAMRoute: Comparison of Diagnostic Solutions
The graphic shows that SAMRoute offers a return on investment in 1 to 2 days per year, compared to on-site diagnostics which require up to 100 days to become profitable.
Section A: Assumptions and infrastructure overview
Total network size, cost per fatality, event count, and attributability
The adjacent table helps you identify the extent of your
infrastructure in kilometers. Values may vary depending on
the counting method used.
Table. Network size.
| Zone type | Network size |
|---|---|
| Urban area | 300 to 3,000 km |
| Department | 3,000 to 30,000 km |
| Region | 30,000 to 100,000 km |
| All of France | 1 to 2 million km (*) |
(*): Depending on the counting method.
The cost of a fatality is estimated between €2 and €5 million.
This figure takes into account different levels of accident severity, as explained below:
- For an accident with no injury, the cost covers only material damages. It ranges between €1,000 and €10,000.
- In the case of minor injuries, medical expenses are added but without lasting effects. The total cost is between €10,000 and €100,000.
- For a serious injury requiring emergency care and resulting in lifelong disabilities, the cost ranges from €100,000 to €1 million.
- In the event of a fatality, the cost includes material damages, healthcare costs, funeral expenses, and the financial consequences related to the loss of relative. The cost reaches several million euros.
Table. Cost of a fatality.
| Accident type | Estimated cost |
|---|---|
| No injury accident | €1,000 to €10,000 |
| Minor injury | €10,000 to €100,000 |
| Serious injury | €100,000 to €1 million |
| Fatality | €2 to €5 million |
The following table shows the number of fatalities per year
(the event) based on the size of the geographic area concerned.
These figures offer a broad perspective on risk, whether for an
urban area, a department, or on a national scale.
Table. Number of fatalities.
| Zone | Number of events (*) |
|---|---|
| Entire France | Around 3,200 |
| Department | 100 to 300 |
| Urban area | 10 to 30 |
(*): Fatalities per year
Attributability represents the causal share attributed to
infrastructure in accidents, expressed as a percentage. A figure
of 100% indicates systematic causality, while 0% means no causality.
Three factors influence accidents.
- Driver behavior, such as non-compliance with rules or driving under the influence, contributes to 60% to 80% of cases.
- A defect in the vehicle is responsible in 5% to 15% of cases.
- Finally, the infrastructure itself is involved in 10% to 20% of situations.
Table. Attributability of Road Accidents.
| Factor | Contribution to Accidents (%) |
|---|---|
| Driver behavior | 60 to 80 |
| Vehicle defect | 5 to 15 |
| Infrastructure | 10 to 20 |
In our calculation, we attribute 1% causality to the
infrastructure, which is highly conservative (10x).
Since this value is constant, it does not impact comparisons
between diagnostics.
However, when interpreting results, it’s essential to remember that we’ve reduced infrastructure's role by a factor of ten — and consequently the risk cost for which it is responsible (see the denominator of the safety ROI threshold defined below).

Section B: Variables specific to SAMRoute
Coverage and total kilometers, annual package, and optional consulting
Three parameters configure the costs associated with SAMRoute.
- The coverage is set to 100% of the network (by default).
- The total kilometers corresponds to the full extent of your network.
- The annual package cost for SAMRoute is pre-filled based on the total kilometers in your network.
- An optional consulting service (post-hoc analysis) can be added for an additional fee (default: €0).
Section C: Variables for alternative diagnostics
External service and internal control
The external service offers a solution with:
- a fixed cost and
- a fee per kilometer covered.
- hourly rates and
- fees per kilometer traveled.
Metric: Breakeven threshold and safety ROI
The breakeven threshold is expressed as a percentage of total risk cost or in days
The safety breakeven threshold
The safety breakeven threshold quantifies the minimum impact
that diagnostics must have on the total risk cost to justify
the diagnostic expenditure.
It is the ratio between:
It is the ratio between:
- the cost of diagnostics — defined in sections B and C, and
- the total risk cost — defined in section A.
- as a percentage, and also
- in days — where 100% corresponds to 365 days.
The safety ROI
By extension, the safety ROI (return on investment) is the ratio between:
- the safety breakeven threshold (expressed as a %), and
- the safety gain (%) targeted by your organization.
Results: 1 day for SAMRoute, 10 for internal control, and 85 for external service
Comparison of SAMRoute pre-diagnosis to external or internal control diagnostics
Each option has a breakeven threshold representing the
minimal impact needed to justify the investment. The key
results (KPIs, green boxes) show these thresholds.
- For SAMRoute, this threshold is 0.3%, or one day.
- For an external service, this threshold is 23%, or 85 days for a 5% coverage.
- For your internal control, this threshold is 2.7%, or 10 days over 5% of the network.
In the table:
Similarly, the graph shows:
- the rows represent your safety gain objectives,
- the columns indicate the profitability of different diagnostics at this level of safety gain.
Similarly, the graph shows:
- the safety gain objective horizontally, and
- the safety ROI on the vertical axis.
Why choose the SAMRoute pre-diagnostic?
Unlike alternative diagnostics, which require on-site
inspections and only cover a fraction of the network,
SAMRoute covers 100% of the network. This comprehensive
coverage allows you to identify risks across all segments,
including those often overlooked, while being extremely
economical.
