The main objective of this article is to present a model of optimum size for the policearea of responsibility (AOR) by taking the factors facilitating crimes intoconsideration. These factors are physical, economic, social and population with radius size ofservice in the AOR. Realization of the capacity in patrolling and the distance to respond toa crime scene within the proper time is considered. According to the analysis, the factorsfacilitating crimes consist of the number of cases per area, development level, populationdensity and types of land usage. The established model developed from an approach fordetermining the AOR size as to cover each group of police stations by substitution with thehighest and lowest possible values of each factor into the model. This approach categorizesthe crime threat into 3 levels: high, medium and low, and divides the usage of land into 8 maintypes: residential, commercial, industrial, mixed, public utility, public support, recreationaland agricultural types. The findings are 1) high level of crime threat leads to smaller size ofthe AOR and 2) the AOR size varies, depending on the type of land usage: the AOR of landusage for commercial type is the smallest whilst the AOR of land usage for agricultural type isthe largest.
