a. Find the general traffic pattern in the freeway network shown in the figure. (Flow rates are in cars/minute.)b. Describe the general traffic pattern when the road whose flow is x4 is closed.c. When x4 = 0, what is the minimum value of x1

Step-by-Step Solution:

Solution Step 1:We get equations from each of the four nodes,plus one equation for the total.Step 2:Rearranging the equation into standard form(and ignoring the last one,which is always satisfied),we getWe then reduce the augmented matrix Then reduced row echelon form is the general solution is
