The purpose of this project is to provide recommendations regarding how to include the value of driving comfort related to road type in economic appraisal of road projects. This is done by using different values of travel time for different road types, where road types with a high level of driving comfort have a lower value of travel time. There is little existing evidence on this, but we have based our recommendations on international literature combined with an analysis of data from the toll road project E18 Arendal–Tvedestrand. Compared to the average value of travel time, we recommend using a 20 percent lower value of travel time on for four-lane highways, and a 15 percent higher travel time on two-lane highways without yellow lane marking. We emphasise that the estimates are uncertain and recommend more research, including collecting and analysing data on the route choice of car travellers.
