When the campaign has ended, all marked locations on the map are scientifically evaluated by the
Vias institute.
The Vias institute developed a useful tool to rank dangerous crossing locations. Factors considered when calculating the score include previous accidents at the location and the severity of those accidents. The presence of schools, bus stops, and playgrounds or sports grounds in the immediate vicinity is also considered in determining the score. Thanks to this tool, the relevant road authorities can relatively easily receive a ranking of locations reported by citizens. This form of “citizen science” creates broad public support, as citizens are actively involved in shaping road safety policy.
