N6 toll road between Galway and Ballinasloe

We were commissioned to undertake Traffic and revenue forecasting for proposed N6 toll road between Galway and Ballinasloe.

The project consisted of approximately 56 kilometres of new dual carriageway road between Galway and Ballinasloe in the west of Ireland. In addition there is a 7 kilometre link road to the Loughrea Bypass, 32 Kilometres of side roads and 4 grade separated junctions. There is a single toll plaza with differential toll levels for cars and three classes of goods vehicle. We provided traffic forecasts for toll plaza design, pavement design and for revenue forecasts. A SATURN highway traffic model was developed based on existing roadside interview and other data. Traffic growth was assessed based on car ownership growth, gross national product (GNP) growth, regional population and employment growth. Traffic forecasts took into account willingness to pay tolls using distributions of value of time by vehicle toll class.
