Analysis of traffic accidents before and after resurfacing measures : resurfacing years 1997 and 1998 in Region West of the Swedish National Road Administration (English)
Abstract [sv]

Detta är den tredje studien om effekten på trafikolyckor av beläggningsåtgärder som Vägverkets Region Väst låtit genomföra. Alla tre har genomförts som före-/efterstudier med 2 år före och 2 år.

I den här redovisade studien, dvs. den tredje i ordning, analyseras vägar som ombelagts under åren 1997 och 1998.

Om alla polisrapporterade olyckor analyseras erhålles en olycksökning efter åtgärd. Analyseras personskadeolyckor för sig erhålls olycksminskningar för båda beläggningsåren. Antalet olyckor minskar även när enbart olyckor med svårt skadade och dödade analyseras. Inget av resultaten är statistiskt säkerställt.

Abstract [en]

This is the third study of the effects on traffic accidents of resurfacing measures that Region West of the Swedish National Road Administration has commissioned. All three have been carried out as before-and-after studies with two years before and two years after the measure.

In the study reported here, the third in order, roads resurfaced during 1997 and 1998 were examined.

When the two resurfacing years are examined individually, an accident increase is obtained for all police-reported accidents after resurfacing. If personal injury accidents are analysed separately, accident decreases are obtained for both resurfacing years: the number of accidents decreases also when only accidents with seriously injured and killed are analysed. None of the results are statistically verified.
