In view of the proposal that vehicles should give way at intersections to vehicles approaching from the right even if these vehicles are defined as slow traffic, the following questions are considered; (1) is there a difference between the outcome of traffic conflicts between cyclists and cars in daylight and in darkness, and (2) are possible differences caused by a decreased perception of cyclists in darkness. At 8 junctions in the town centre of leiden conflict observations between cars and cyclists were made. Significant differences were observed in the outcome of priority conflicts between cars and cyclists in daylight and in darkness. The reduced perception of the cyclists was not a main factor mainly due to more care on the part of the cyclists and increased detection measures by the cyclist. This report is only a part of the overall research into the priority modification.
