Rapportering från ett samverkansprojekt för bättre rattfylleristatistik: förslag till pilotstudie av rattfylleriets omfattning
2006 (Swedish)Report (Other (popular science, discussion, etc.))
The most important contribution to improved knowledge of the prevalence of drink-driving in Sweden is a sample survey where drivers are tested at randomly selected sites and time points. The prerequisites for such a study have been investigated in this project, which has been conducted in collaboration with the head of the traffic police in three counties (Södermanland, Östergötland and Örebro) and representatives from the National Board of Forensic Medicine. The main aim of the study was to propose a method of how to conduct the survey; a proposition of a pilot study is presented here. Other issues regarding the statistics from random breath tests, police reports from road traffic accidents, and driving under the influence of other drugs than alcohol is also discussed. The aim of the pilot study is partly to find out the prevalence of drink-driving among the car drivers in the selected counties, partly to test the methodology suggested in this report. It is not possible in practice to investigate the whole road network and to cover all hours of the day. Therefore, a number of limitations are suggested. Both the urban and rural network is limited to the most frequently used roads. All days a week will be observed, but the working hours of the traffic police restricts the study to the time between 7 and 23. About 95 percent of the total traffic volume is produced within this time frame. The study will be spread out during a whole year in order to cover all seasons. The total sample size is set to 25,000 tests. This number is set in consideration of the police capacity.
