摘要

Since the cost of building low-volume feeder roads in developing countries is relatively low, it is difficult to justify determining detailed costs and benefits of projects, or undertaking detailed social and environmental impact studies. The consumer surplus method strikes a balance between being rigorous and keeping data collection and analysis requirements simple. In most cases, the requirement will be to rank potential feeder road projects within budget constraints, rather than to determine economic indicators. This simplifies the methodology because only relative values or changes in values need to be determined.
