If the portion of the roundabout between A and B has an estimated traffic flow of from 6[e] to 8[a] cars per hour, what is the estimated traffic flow between C and A, and between B and C? PIN is 24768 X1=AB X2=BC X3=AC A= X3 + 200 = 165 + X1 X1-X3=35 B= X1 + 50 = X2 + 100 X1 - X2 =50 C= X2 +200 = 185 + X3 X2 - X3= -15 Point A is 6[e] =68 Point B is 8[a] =82 From A to B the traffic flow is from 68 to 82 cars per hour. AB=68 x1 82 CA= 68 X3 - 15 82 (1) 68 X3 - 15 68 + 15 X3 83 X3 (2) X3 - 15 82 X3 82 + 15 X3 97 The estimated flow between C and A is 83 X 3 97 BC= 68 X2 -50 82 (1) 68 X2 -50 68 + 50 X2 118 X2 (2) X2 - 50 82 X2 82 + 50 X2 132 The estimated traffic flow between B and C is 118 X 2 132
