the aim of this 'human factor' study is to identify indications for the potential safety of infrastructural engineering measures. A framework is presented in which the safety of cyclists is based on the characteristics of the infrastructure in relation to the behaviour of users. Complexity, probability and severity of failure, predictability and complementarity of the priority rule are considered to be important determinants of safety. It has been determined how complexity, probability and severity of failure can be applied to the safety analysis of an engineering design. By analysing the intended uses of the facilities, it is possible to gain an impression of the safety of a measure. When these analyses are supplemented with data about how cyclists actually behave, an impression can be formed about how the facility will be used in practice. The study asserts that knowledge obtained from study into the discrepancies between the intended use of the facilities and the actual behaviour can help to realize a design which corresponds more closely to human potential and limitations.
