How the Interpretation of Drivers' Behavior in Virtual Environment Can Become a Road Design Tool: A Case Study

<table>The operative speed is that speed which is not exceeded by the 85% of vehicles. In the diagram, that represents the distribution of velocities in a road section, the 100% of vehicles has a speed  higher than 0 km/h; the 15% has a speed higher than 74 km/h. The operative speed is 74 km/h (it belongs to 100% −15% of vehicles).</table>
