    Sidoläges- och hastighetsmätning på Rv40 Borås-Bollebygd1989Report (Other academic)
    Abstract [sv]

    Motortrafiksdelen av RV 40 mellan Borås och Göteborg har fått ett ganska dåligt rykte vad gäller olycksfrekvens. Vägverket har med anledning av detta ansett det vara nödvändigt att vidta åtgärder, varför man på vissa sträckor har ändrat vägen från 2-fältsväg med breda vägrenar till 3-fältsväg med smala vägrenar

    Syftet med den nya målningen har primärt varit att reducera antalet omkörningar utan tillräcklig siktlängd genom att utföra vägen växelvis med två körfält i ena och ett körfält i andra riktningen. Sekundära effekter av den alternativa målningen kan tänkas bli förändringar i hastigheter och spridning i sidolägesplacering. Denna studie behandlar dessa två sistnämnda parametrar.

    Samtidigt bruk av dimljus och halvljus1994Report (Other academic)
    Abstract [sv]

    Det alltmer utbredda bruket av samtidig användning av halvljus och dimljus har medfört att man frågat sig om detta kan vara acceptabelt för trafiksituationen under mörkertrafik. Det ordinarie halvljuset har en skarp ljus-mörkergräns i avsikt att få en så liten bländning möjligt av mötande trafik. Ett tillskott av bländning från ytterligare ljuskällor skulle kunna vara till nackdel för de förare som möter dessa bilar. Frågan är även hur siktsträckan till hinder påverkas vid ett möte mellan två bilar som båda utnyttjar både ordinarie halvljus och dimljus. För att utreda detta har ett siktsträckeförsök utförts, där olika kombinationer av halvljus och dimljus använts.
