At present, workin road traffic safety is expanding from injury prevention toinclude also accident prevention. For accident preventive measuresto be effective, knowledge is needed about common causal factorsthat contribute to the occurrence of accidents. This paper aimstowards identification of such common factors for a specific subsetof all road accidents, namely intersection accidents. The data usedfor the study consists of in-depth investigation material fromsixteen intersection accidents that have been investigated by amulti-disciplinary accident investigation team. Data analysis wasperformed using DREAM, a MTO based accident investigation method.The results indicate that cognitive bias, hidden information,inadequate design of traffic environment, and competing task arecommon contributing factors of intersection accidents. Also, thedistribution of factors for different collision path scenarios wasstudied, and several patterns in the distribution were discovered.These patterns were then compared to the results of another studywith a similar aim, but based on database statistics rather thatin-depth data. The conclusion of the comparison is that the DREAMmethod, in combination with in-depth accident data, provides adeeper and more detailed insight into how and why different factorscontribute to accidents, and these insights are well suited foraccident preventive work.
