The influence of delineator posts on driving behaviour (English)
Abstract [sv]

För att förbättra den visuella ledningen i mörkertrafik är flertalet nordiska vägar utrustade med kantstolpar. Hur dessa sätts upp längs med vägen varierar emellertid mellan länderna; på tvåfältsvägar är exempelvis avståndet mellan två kantstolpar 100 meter i Danmark, medan det är 50 meter i Sverige. Syftet med föreliggande studie var att undersöka vilken konfiguration som ger det bästa trafikantbeteendet. Ytterligare ett syfte var att söka den på stolpen monterade reflektorns optimala synavstånd. Resultaten kan ligga till grund för en harmonisering av de nordiska regelverken. Studien har utförts i VTI:s och SINTEF:s körsimulatorer och har beträffande konfigurationen även validerats på reell väg i Finland av VTT. I VTI:s simulator har försökspersoner i mörker fait köra en vägslinga innehållande sju olika konfigurationer, medan studien på SINTEF innehöll kantstolpar vars reflexer kunde ses på 100, 200 eller 400 meter. I båda simulatorerna mättes hastigheten kontinuerligt. Resultaten visade att den konfiguration som idag används i Danmark är att föredra. Den ger samma eller bättre körbeteende än övriga konfigurationer, men till lägre pris. Reflexens optimala synbarhet skattades vara 100-200 meter.

Abstract [en]

In order to improve the visual guidance in night-time traffic most Nordic roads are equipped with delineator posts. The configuration of these posts vary between the countries; as an example the distance between two delineator posts is 100 metres in Denmark, while it is 50 metres in Sweden. The aim of the present study was to investigate which delineator post configuration that gives the best driving behavior. Furthermore, the optimal visibility distance of the retro-reflector of the post was estimated. The results can be used for a harmonization of the Nordic regulations regarding delineator posts. The study was conducted in the VTI and SINTEF driving simulators. The study of configuration (VTI) was validated on the real road in Finland by VTT. In the VTI simulator subjects drove in the dark a loop containing seven different delineator posts configurations, while the study at SINTEF used a loop where the retro-reflectors of the posts had a night-time visibility distance of 100, 200 or 400 metres. In both simulators the speed was registered continuously. The results show that the configuration which today is used in Denmark is to prefer. This configuration gives equal or better driving behavior than other configurations, but to a lower price. The optimal visibility distance of the retro-reflectometer was estimated to 100-200 metres.
