Abstract
Description
The basic goal of an investment in real estate is to make the highest positive net return possible, and the process of attaining
this commences at the site selection stage with accessibility being of paramount consideration. Many investors, appraisers,
planners and developers often base site selection and analysis of accessibility on intuition and mere physical observation of
neighborhoods without scientific approach The aim of this study is therefore to examine the application of graph-theoretic
analysis in resolving the challenge of improper site selection process and accessibility issues in real estate planning
development. In attaining the aim, the satellite map of the study area was derived and converted into linear graph regardless of
the width, length and quality of roads. The nodal points of roads that form the network were serially numbered and translated
into simple matrix of the number to obtain the accessibility indices for the ranking of access routes in the study area. The study
found that the graph-theoretic approach was useful in analyzing ami resolving the accessibility and site selection issues 111 real
estate development p1ocess. The findings would provide better understanding of determination of accessibility which hithel1o
had been done by mere intuition by real estate appraisers and planners through the application of the approach This is
applicable to inform developers take decision relating to choice of locations by scientifically establishing the most accessibilily
location and thus assists in site selection Also, it would assist the development appraisers in the ranking of several of locations
along al1erial routes with a view to determining sustainable physical developments.
