There is a need for ADB projects to further strengthen the quality of economic analysis, particularly in the areas of quantification and valuation of economic benefits, and shadow pricing, to strengthen reporting on project performance. The methodology needs to be better understood by all, and more consistency is required by ADB staff, consultants, and the government in such analyses. Perhaps better and more explicit guidelines are called for. On road crashes in Yunnan which remain high and appear to be increasing, this suggests that either the road safety features included in the project were inadequate, and/or increased traffic volumes and vehicle speeds inevitably lead to more fatal accidents. It was unwise to target the reduction in such fatalities at the outset without more research into the causes of such accidents. The relationship between road improvements and road crash fatalities needs to be researched further.
