This manual presents the Roads Economic Decision Model (RED) developed to improve the decision-making process for the development and maintenance of low-volume rural roads.
Transport Infrastructure (RTI) - its "public goods "nature - was identified as the primary reason why governments and, therefore, planners must be involved in providing it. The concept of a "public service industry" is introduced in Chapter I as a way of analyzing the elements of a posited rural access planning framework. A distinction was made between the provision of public goods and their production.
This Note presents the Roads Economic Decision Model (RED) that performs an economic evaluation of road investments and maintenance options customized to the characteristics of low-volume roads such as: a) high uncertainty of the assessment of traffic, road condition, and future maintenance of unpaved roads; b) periods during a year with disrupted passability; c) levels of service and corresponding road user costs defined not lonely through roughness; d) high potential to influence economic development; and e) beneficiaries other than motorized road users.
