ARRANGEMENT OF MOTOR VEHICLE RACING CIRCUITS, IN PARTICULAR FOR MOTORCARS, WHICH FACILITATES OVERTAKING MANEUVERS IN BENDS
The invention concerns an arrangement (8) of a motorcar racing circuit, having at least one bend (1) comprising a first circular segment (2), including at least one overtaking lane (9), an access section (10) to said lane (9), and an exit stretch (11) connected to said circuit. The overtaking lane (9) outside the bend (1) includes a second circular segment (12) concentric with the first segment (2). Said lane has a superelevation and/or a surface based on the characteristics of said first segment (2), such that the time of travel round the bend (1, 8) by a vehicle is the same, as when the vehicle travels along the initial bend (1) or the overtaking lane (8). A water stream, or flexible blocks or vibrators separate de overtaking lane (8) from the initial bend (1). The invention is applicable to motorcar, motorcycle or side-car racing.
