Communication between people on the Héðinfjarðar-tunnel: Traffic and comparison with traffic forecast
A traffic forecast was made prior to the opening of the Héðinsfjörður-tunnels between the towns Siglufjörður and Ólafsfjörður in 2010. The forecast was based on a traffic survey where all traffic in the northern Tröllaskagi peninsula was stopped on a total four days in summer and winter. The forecas...
