In the proposed clustering algorithm, the formation is initiated based on the direction which the vehicle will take after crossing the intersection. Fig. 1 presents a screenshot of a lane which is split into different regions (regions between the dark lines in Fig. 1). The size of these regions is equivalent to the radio range of the vehicles. With the GPS information, each vehicle computes its travel path at the intersection based on the source and the destination. More precisely, the direction it will take after crossing the intersection will be known.
