This report presents the final results of the first stage of a research project on judgements of risk and decision making by traffic participants. Behavioural observations collected from cyclists turning left at different intersections are coupled with a theoretical model for the behaviour of traffic participants. More specifically, observed behaviour of cyclists in approaching the intersections is described and analyzed. The limited usefulness of observational data for interpretation in terms of personal judgements and decision processes made it necessary to rely upon a number of hypothetical, though plausible, decision scenarios. The outline of a new experiment is given in order to collect data which overcome these interpretation problems and test the value of some of the hypotheses formulated. (Author/publisher)
