Traffic safety at grade crossings between road and rail - 1999-2004 (English)
Abstract [en]

For many years, Banverket (Swedish rail administration) has done a lot of work to improve traffic safety at grade crossings between road and rail. The most dangerous, and worst controlled, grade crossings have been systematically upgraded or quite simply removed. In 25 years, 2 out of 3 grade crossings have disappeared. 75% of all grade crossings which were uncontrolled in the 1970s have been given new forms of control or dismantled. The number of accidents has decreased by 70%.

The number of accidents on the rail network has radically decreased in the past 50 years. In the 1950s there were 150 accidents at grade crossings every year, in the 1970s about 100, and at the turn of the century about 30, in a continual downward trend. This applies to accidents as a whole, to a large extent due to the disappearance of so many grade crossings, but the number of accidents has also decreased for the comparable grade crossing types. Traffic safety has also radically improved for comparable grade crossings. This can be seen in concrete terms when a study is made of the accident rate, i.e. the number of accidents divided by the traffic load on road and railway (annual basis):

  • fully skirted barrier: 0.20 (1973-77 0.53)
  • half barrier: 0.27 (1973-77 1.10)
  • acoustic/light signal: 9.01 (1973-77 10.41)
  • crossed bar signs: 23.06 (1973-77 34.31).

The above does not compare like with like. Grade crossings now are completely different from those in the 1970s, even though the external form of control is the same.

Abstract [sv]

Banverket har under många år bedrivit ett omfattande arbete för att förbättra trafiksäkerheten i plankorsningar mellan väg och järnväg. De farligaste, och sämst reglerade, plankorsningarna har systematiskt sanerats eller helt enkelt byggts bort. På 25 år har 2 av 3 plankorsningar försvunnit. Av alla plankorsningar som var oreglerade på 1970-talet har 75 % ändrat regleringsform eller rivits.

På 1950-talet inträffade 150 olyckor i plankorsningar per år, på 1970-talet ungefär 100 och runt sekelskiftet ungefär 30 i en kontinuerligt nedåtstigande trend. Det gäller totalt sett, mycket beroende på att så många plankorsningar försvunnit, men antalet olyckor har också minskat för de jämförbara plankorsningstyperna.

Trafiksäkerheten har förbättrats radikalt för jämförbara plankorsningar. Konkret framgår det om man studerar olyckskvoten, det vill säga antalet olyckor dividerad med trafikbelastningen på väg och järnväg (årsbasis):

  • helbom 0,20 (1973–1977 0,53)
  • halvbom 0,27 (1973–1977 1,10)
  • ljud/ljus 9,01 (1973–1977 10,41)
  • kryssmärken 23,06 (1973–1977 34,31)

Även om jämförelsen mellan åren haltar i flera väsentliga avseenden är skillnaden mellan 1970-talet och sekelskiftet så stor att det rimligen måste förklaras av att plankorsningar var helt olika då jämfört med nu även om den yttre regleringsformen är densamma.
