This deliverable called D3.4 has the purpose to summarize the overview of infrastructure design criteria and legislation with the emphasis on roads, bridges and tunnels. For pavements, there is no European design criteria. So the national design criteria for various European countries have been listed and explained. The parameters involved in these design criteria and to be chosen are parameters linked to the materials or structures, to climatic actions applied on the pavement all over the year and traffic. For traffic, the effect of a traffic or a given vehicle is evaluated through comparison with the effect of equivalent axle loads. For bridges, European design criteria exist: the Eurocodes (Eurocode 0, Eurocode 1, ... to Eurocode 8). These building codes are applicable all over Europe; in fact, their application is mandatory since 2010. Only partial, safety coefficients (±- factors) vary from one country to another. These factors can be found in the respective national appendixes, some of them are summarized here. As for tunnels, it has been shown in report D3.2 that only the horizontal geometry of tunnels is designed according to traffic, as would be a road and its pavement. Therefore, the issue with traffic in tunnels is a problem of parking lots and management of truck passing's through the tunnels. The design criteria for pavements and bridges can now be used for the definition of Smart Infrastructure Access Policy (task 3.5 of project FALCON).
