Excerpt
The Highway Design and Maintenance Standard Model (HDM) is a computer program for analyzing the total transport costs of alternative road improvement and maintenance strategies through life-cycle economic evaluation. The program provides detailed modeling of pavement deterioration and maintenance effects, and calculates annual costs of road construction, maintenance, vehicle operation, and travel time. Accidents and other impacts can be added exogenously to the economic evaluation. The first personal computer version of HDM, released by the World Bank in 1989, is widely used in the evaluation of specific road proposals, national or regional road investments analysis, and road maintenance policy assessment. The second personal computer version of HDM, released by the World Bank in 1995 in this package, maintains total compatibility with the previous HDM and addresses its significant limitation that it does not take account of traffic congestion, and its effects on traffic speeds, travel times and road user costs. That is, the 1995 HDM contains congestion analysis capabilities but maintains all the other characteristics of 1989 HDM...
