$26-2.$ Consider the time$-$space diagram for this problem. For

the signals shown:

$($a$)$ What is the NB progression speed?

$($b$)$ What is the NB bandwidth and bandwidth capac$-$

ity? Assume a saturation headway of $2\mathrm{.}0$stveh.

$($c$)$ What is the bandwidth in the SB direction for the

same desired speed as the NB progression speed?

What is the SB bandwidth capacity for this situation?

$($d$)$ A new development introduces a major drive$-$

way that must be signalized between intersections

$2$ and $3.$ It requires $15$ seconds of green out of the

$60-$second system cycle length. Assuming that

you had complete flexibility as to the exact loca$-$

tion of the new driveway, where would you

place it$?$ Why?
