intersection the intersection in fig9 has three phases in the first phase shown in fig9 a traffic is allowed to turn from the a lanes to the b lanes and the b prime lanes in the second phase shown in fig9 b traffic is allowed to proceed in the b prime direction and to turn from the b prime lanes to the a prime lanes in the third phase shown in fig9 c traffic is allowed to proceed in the b direction and the b prime direction and turns are allowed from the b lanes to the a prime lanes a u201c t u201d intersection incorporating a protected turn around lane is illustrated in fig1 in fig1 a protected turn around lane is provided for turns from the a lanes to the b prime lanes the resulting intersection has two phases the first phase illustrated in fig1 a allows traffic to proceed in the b direction and the b prime direction and a right turn from the b lanes to the a prime lanes the first phase also allows a yielded right turn from the a lanes to the b lanes the second phase illustrated in fig1 b allows traffic to proceed in the b prime direction and for turns from the b prime lanes to the a prime lanes and from the a lanes to the b lanes the second phase also allows a yielded right turn from the b lanes to the a prime lanes in fig1 the concrete structure 1005 that forms the protected turn around lane bulges to the west fig1 c and 10d.
