Integration of analytical hierarchy process (AHP) and geographical information system (GIS) F or potential crime area analysis

Abstract

Increasing crime rates in a community can be associated with several factors such as land use, economics ac-tivities, building use and demography. A preliminary survey conducted showed that land use and building use are potential cofactors that contribute to a crime. In this research, we attempt to develop a model to pre-dict crime areas by utilizing these two cofactors. To pursue this endeavor, Analytical Hierarchy Proces (AHP) method and Geographical Information System (GIS) were implemented. AHP is used to produce consistent and realistic weight values of crime factors by calculating the consistency ratio (CR) which can thereafter be used for validation. Though, the GIS is applied to visualize the weights obtained from the AHP results in spatial mapping in order to identify potential crime areas, which were classified as either high, me-dium or low. The data set for this research has been drawn from UGISP Sdn Bhd, which covers the areas of Wilayah Persekutuan Kuala Lumpur (WPKL). From the result, it shows that the potential crime areas are Kuala Lumpur, Bukit Indah, Jinjang and Bandar Tun Razak. As a conclusion, our model would assist the au-thorities (i.e., Dewan Bandaraya Kuala Lumpur, Malaysia) to identify and rank the potential crime areas, and then they can plan a strategy to monitor this matter properly.
