Concentration spatiale des accidents de la route : méthode d'identification des zones noires basée sur l'autocorrélation spatiale application et étude de sensibilité

The objective is to identify places of spatial concentration of road accidents by black zones rather than blackspots. The application of a geographical analysis method based on local measures of spatial autocorrelation permits to localise black zones.The relevance of the method is considered; a sens...
