Abstract
Cyclists and moped riders are high risk traffic participants. in 31% of the registered traffic accidents in the Netherlands which lead to personal injury of the driver, at least one cy- clist is involved and 27% of the drivers killed is a cyclist. Required behaviour can be formalized in a normative task ana- lysis. Such a normative task- analysis was carried out to pro- vide a description of a normative cycling performance under all possible traffic conditions. It is shown that generally young cyclists are performing rather inadequately in traffic as measured by accident numbers and observed behaviour.
