THE INFLUENCE OF ASYMMETRIES IN THE DRIVER/CAR AND ROAD TRAFFIC SYSTEM ON THE OCCURRENCE OF ACCIDENTS

DER EINFLUSS DER ASYMMETRIEN IM SYSTEM FAHRER FAHRZEUG UND IM STRASSENVERKEHR AUF DAS UNFALLGESCHEHEN

Some partly unpublished experiments lead to the conclusion that asymmetry in traffic has a great influence on accident occurrence. It has been shown that accidents occur much more frequently on left hand bends and on left turns than on right hand bends and on right turns. The report describes in detail an attempt to explain the increased accident risk on left hand bends. 17 students of the Technical High School, Cologne, drove a circular route of 65 m in diameter, under certain precisely described conditions, whilst constantly changing driving directions. Since the frequency of the heart beat is the best indicator of stress, the approximately 29% higher increase in the heart beat frequency in trips involving left hand bends is the most striking result of the experiment. With the exclusion of other possible influences the basis of this phenomenon can be seen in the asymmetry of the sitting position of the driver especially due to the inadequate posture of the driving seat. However, further tests should strengthen this hypothesis. /TRRL/
