Cluster analysis, also known as cluster analysis or numerical taxonomy, is the procedure by which
observations of a data set are clustered in groups or clusters, so that the objects are homogeneous within the group
and the groups are as heterogeneous as possible when compared between them. The main purpose of the chapter is
to study the clustering techniques so as to find a suitable method for automatic grouping of traffic events in
interurban scenarios. To achieve this goal, we must first take into account the stages of clustering techniques.
Keywords: Clustering, Traffic events.
