59 sec is the delay for left turning a d 21 s is calculated as delay for through and right movement. We need to consider both of them for the delay of the approach.
For calculating intersection delays, refer to the DI formula in video 19:09 sec, we need to consider the sum of all VA that we have in each approach for the denominator. The same sum will be used for the numerator but each VA should be multiplied with corresponding dA and then add all together.

for approach EB we got two value of delay which is 59s and 21s, so for approach delay we choose the smallest one, am I right?

@@LifeLearningHub How do we detemined the last row of intesection delay and LOS? What formula do we need to use?
What book did you use as a source for this tutorial?
It was not a specific book to i clude this question but it was an image from book Traffic & Highway Engineering by Garber.
While we calculating intersection delay,should we take which value VA?
