Where it applies
Built in Norway, made for tunnels everywhere
The method is global; the compliance layer is European; the rules and the data are national. That separation is what makes the model portable.
PIARC is the World Road Association, and its road tunnel methodology is used far beyond Europe. Tunnel Control is built on that framework, which is why the analysis is not specific to any one country.
EU Directive 2004/54/EC sits on top as the European compliance layer. Where a tunnel is subject to it, the model evaluates it requirement by requirement.
National regulations and national road databases are added per country, as their own layers. Norway is the first — because that is where the product was built and where its regulatory mapping is deepest — and further countries are added as content, not as new code.
We do not publish tunnel counts per country unless we can point to the official register they come from. Where such a figure appears on a country page, its source is named alongside it.
Country layers

National regulations, technical standards and the national road database. Page in Norwegian.
Further country layers are added on request. Because the national rules and data sources are separate layers, adding a country is a matter of mapping its regulations — not of rebuilding the method.

Tell us which regulations you answer to. Mapping a new national layer is the work we do to open a market — and it starts with a conversation, not a contract.
