Lesson
With climate change exerting new and increasing demands on road and bridge networks, future economic analyses for transport projects should take a broader perspective in calculating economic benefits. The economic analysis for this project compared with-project and without-project scenarios to derive its economic benefits. The definition of the with-project scenario assumed time and vehicle operating cost savings from less traffic congestion and improved traffic flow. The benefits from less congestion accounted for 93% of the total net benefits.
