THE LOCAL SPATIAL AUTOCORRELATION AND THE KERNEL METHOD FOR IDENTIFYING BLACK ZONES: A COMPARATIVE APPROACH

Two methos are presented and compared in this paper for identifying and delimiting road sections characterized by concentration of road accidents: one method based on spatial autocorrelation indices, the other one on kernel estimators. The paper shows that although the two methods start from a different conceptual approach, both may provide quite similar results under a specific choice of parameters and lead to a definition of non-contiguous black zones.
