Lesson
Exercising greater care in estimating traffic demand projections is of utmost importance. Overly optimistic forecasts of traffic volumes can stem from using outdated or arbitrary parameters and unrealistic assumptions. For instance, elasticity values of road transport demand may have changed over time. Also, the use of national GDP as a proxy for economic activities at the regional or local level could result in unrealistic traffic forecasts. Both of these could lead to an overly designed project.

Lesson
Program preparation stage benefits from upfront capacity development. Specifically, institutional capacity assessment of executing and implementing agencies at the onset is vital in planning for appropriate measures to support the agencies during the program. Technical assistance for capacity building helps complement such assessments by filling in gaps in capacity to enhance their financial, procurement, and technical capacity skills.

More robust due diligence is needed during project design and formulation to enable the closest possible cost estimates and to set aside enough resources to cover contingencies. This can save considerable time. The scope of the ADB-financed East-West Highway Improvement Project, approved in 2005, included two sections of the east-west highway
