Road safety effect of speed cameras established in 2006 : analysis of injuries in 2007-2008 (English)
Abstract [sv]

Under 2006 inledde Vägverket och Rikspolisstyrelsen satsningen på en modernare variant av automatisk trafiksäkerhetskontroll (ATK). Då infördes ett nytt system som via digital teknik medger betydligt högre grad av automatisering av hastighetskontrollerna. VTI har utvärderat alla 51 helt nya (där det inte tidigare fanns kameror) ATK-sträckor i en så kallad före-efter- studie. I en så kallad med-utan-studie ingår, förutom ovannämnda helt nya sträckor, även 45 av totalt 55 nygamla (som haft äldre system under åren t.o.m. 2005) ATK-sträckor som installerades 2006. Vid före-efter-studien jämförs här utfallet under föreåren 2003–2005 med utfallet efteråren 2007–2008. Med hjälp av med-utan-studier jämförs här de faktiska utfallen under 2007–2008 med normala eller förväntade utfall för samma år och samma typ av vägar utan kameraövervakning. Före-efter-studien och med-utan-studierna ger ungefär samma resultat vilket är en styrka. Resultaten pekar på att ATK reducerar antalet dödade med ca 30 procent och antalet DSS (dödade och svårt skadade) med ca 25 procent. Resultatet avseende antalet dödade är fortfarande inte helt statistiskt säkerställt (vad gäller effekt signifikant skilt ifrån noll). Detta kan dock mycket väl förklaras av att det statistiska olycksmaterialet fortfarande är litet.

Abstract [en]

During 2006, the Swedish Road Administration and the National Police Board began the introduction of a more modern version of automatic traffic safety control (ATSC). A new system, which enables a considerably greater degree of automation to be used in speed controls via digital technology, was introduced. VTI has evaluated all 51 first time ATSC sections (where there were no cameras before) in a before-after study. A with-without study includes, apart from the above first time sections, also 45 of a total of 55 upgraded ATSC sections (which had the older system during the period up to 2005) that were installed in 2006. In the before-after study, the results for the before years 2003–2005 are compared with the results in the after years 2007–2008. With the help of with-without studies, the actual results during 2007–2008 are compared with normal or expected results for the same years and the same types of roads without camera surveillance. The before-after study and the with-without studies produce approximately the same result, which is a strong point. The results suggest that ATSC reduces the number of fatalities by about 30 per cent and the number of fatatites and serious injuries by about 25 per cent. The result concerning the number of fatalities is still not fully statistically verified (as regards effect significantly different from zero). The probable explanation for this, however, is that the statistical accident material is still small
