It is expected that the following preliminary sample outputs can be further enhanced in the future with an increased number of data, and more in depth level of detail for each data in order to:

• monitor country road cost variations at different stages, from estimate to contract and actual costs;

• assess road costs variations overtime;

• compare road costs among states and regions, different financing sources, procurement methodologies (advertisement), etc;

• establish relationships with different types of terrain, climate, regions, construction technologies, etc.; and

• generate the data that is needed for other road cost related studies like life cycle analysis applied in HDM-4.
