The AT-GRADE "T" INTERSECTION ROAD SYSTEM WITH LEFT TURN is a road junction that meets or crosses at the same level, which is formed by three intersections, as minimum: two microintersections (1 and 3) and a main intersection (2). The microintersections are useful for controlling the left turn circulation such that controlling said movement; an exclusive lane (4) for leading the left turn is built. The purpose is that the microintersections and the main intersection be controlled by traffic lights, coordinated, at two phases and with a short cycle length.
