The purposes of the study were to compare road safety in new residential districts with traffic separation but with different lay-outs and to analyze the location of accidents and their connection with the traffic environment. Accident and population statistics were collected for 1969-72 for eight different more recent residential districts with traffic separation outside Gothenburg. These districts were found to have a high degree of road safety in terms of number of accidents involving personal injury compared to older districts with through traffic and a mixture of car traffic and pedestrians. Those more recent districts with internal feeder traffic had annual accident rates double those of more recent districts with external feeder traffic. Hardly any accidents had occurred on short service streets. A formula is presented where the number of accidents is A function of traffic generated measured in vehicle km. Many individual accidents can according to the authors probably be explained by mistakes and drawbacks in the lay-out of the traffic environment.
