Samenvatting
The concept of sustainable traffic safety is used in the Netherlands and usually it includes the following: 1) an infrastructure whose design is adapted to the limitations of human capabilities; 2) vehicles equipped to facilitate human tasks and constructed so as to optimally protect people, vulnerable as they are; and 3) traffic participants who are adequately educated, informed and, where necessary, monitored. The paper details the concept especially when it comes to the categorisation of the road network using different criteria.
