This analysis considers the economic cost of congestion within the Greater Dublin Area (GDA) over the period 2022-2040. This paper builds on the 2017 Costs of Congestion analysis carried out by the Department of Transport, although the results are not directly comparable due to methodological differences. The results of this analysis indicate that congestion will increase significantly over the coming decades within the GDA, driven by population and economic growth. Investment in transport infrastructure, planned over the coming decades, does lead to a reduction in the rate of increase in the cost of congestion. However, additional levels of modal shift to sustainable transport modes or reduction in transport demand would be required to reduce the increase in the cost of congestion. The analysis also models the impact of an alternative future scenario which considers a reduction in transport demand due to increased working from home, which also helps reduce the rate of growth in the cost of congestion.
