For this question, I did not understand how did you draw the space$-$time diagram, could you clarify on the diagram itself how did you take the offsets, besides I do not see the rouge time,??I need more clarification, please.

A two$-$way artery that is composes of five intersections with cycle time of $60$ seconds. The data given

are the following:

The capacity for the rising direction is $400p\frac{c}{h}.$

The capacity for the descending direction is $200p\frac{c}{h}.$

The optimal solution is given by the following:

The bandwidth of the rising direction is $20\mathrm{.}7$ seconds and it is $11\mathrm{.}6$ seconds for the descending width.

The offsets between the middles of the red phases are in the following table:

Represent the bandwidths on the time$-$space diagram.
