Development of Road Selection Model for Transportation Improvement with Minimum Compensation Costs in Upgrading Informal Settlements

Selection of roads for improvement of transport network with minimum demolition of houses required in roads widening has been a challenge for many years in upgrading informal settlements. The problem is compounded by lack of a methodological tool required to assist decision makers on selecting roads that can be widened and improved for improvement of transport network with minimum demolition of houses and compensation costs. This paper is therefore reporting upon a study that has developed a Road Selection Model (RSM) within a framework of Multiple Criteria Decision Making (MCDM) models for selecting roads for improvement of transport network with minimum demolition of houses and compensation costs. The model is formulated based on the roads Functional Performance Criteria (FPC) and Space Syntax Criteria (SSC). It can be used to support decision making pertaining to the selection of roads for widening when upgrading informal settlements.
