A techno-economic rating system for highways using discrete multi-criteria analysis

In developing countries, like Bangladesh, priority to upgrade a national highway is mainly based on technical aspects like daily traffic demands; whereas due consideration to economic factors is generally neglected. Based on a few parameters, if highways are rated keeping in mind some social economic attributes, significant contribution to our infrastructure-based economy could be made. Socio-economic parameters are also considered as determining factors to relevant infrastructure implementation. Combination of socio-parameters, such as social viability, accident rate with technical parameters like daily demand, and amount of axle loads will offer sound retrospective of the exiting road systems. The objective of the present paper is to develop a rating system for prioritization of highways using discrete multi-criteria analysis.
