Abstract [sv]

VTI has, by commission of WSP, compared the quality-of-service of an alternative rural road design to the performance of the existing road on a section of the national route E18. This studied part of E18 is located between Karlskoga and Lekhyttan. The alternative design has separated oncoming lanes and a lane design that follows that of the existing road with an addition of two 1,5 km long overtaking sections. The total length of the road is 15 km and no substantial traffic flows enter or exit the road along the studied stretch. All analyses were to be based on simulation results of the VTI rural traffic simulation model, RuTSim. AADT along the road has been estimated to 13 280 vehicles for the design horizon year 2025. Two hourly traffic flows for the simulation were constructed based on this estimate. One of the flows was set to 10.0 per cent of AADT for passenger cars and 7.65 per cent of AADT for heavy vehicles in order to correspond to the flow during the design hour. The other flow, 6.2 per cent of AADT for both passenger cars and heavy vehicles, corresponds to the average weekday traffic volume.
