Subject(s): Online resources: Abstract: Studien syftar till att studera effekter av varierande vägtunnelmiljöers inverkan på förarprestation (utifrån kända prestationsmått såsom Lane Deviation, PDT och RT). Huvudfrågan är hur faktiskt (objektivt) liksom upplevt (subjektivt) körbeteende påverkas under simulatorkörning med varierande betingelser av tunnelmiljö (ökad belastning i form av informationsmängd, händelser etc.) och hur detta kan relateras till ökad tunnelsäkerhet.Abstract: In earlier Swedish studies performed both in simulator and on-road it has been demonstrated that reaction time of drivers are affected by the complexity of the road environment (Patten et al., 2003). This was one of the results obtained in the Swedish investigation on the use of mobile phones and IT-devices in road traffic. Typically, a more complex road environment (e.g., urban traffic) can be defined as more mentally loading due to increased information processing requirements, with no or little secondary task involvement. Moreover, a recent report from PIARC (World Road Association) committee of road tunnel operation recommends that mobile phones conversations by the drivers should be terminated before entering larger tunnels (longer than 1 km) due to an increased risk of driver inattention and mental workload etc. (Buvik, Ceci, Evans et al., 2008). This recommendation has not been discussed extensively or transformed into a rule or legal proposal in many countries (instead various hands free legislations exist in many EU countries which are believed to aid the situation). The purpose of this project is to study the impact from varied road tunnel designs and environments on driver performance (from well known measures like LD, PDT/PVT, NASA-TLX and RT). A main question is how observed (objective) as well as perceived (subjective) driver behaviour is affected during simulated tunnel driving in different conditions with varied mental workload (increasing workload depending on amount of information, traffic situations etc.) and how this can be related to increased tunnel safety.
