A traffic signal control is being designed for a four$-$leg intersection on a divided highway with the characteristics shown in the table below.

N$-$S Approaches E$-$W Approaches

Median width, $($ft$)1612$

Number of $12$ ft lanes on each approach $32$

Design speed, mph $5040$

Grade $0\%3\%$

Determine the minimum green times $($in s$)$ for each approach if the effective crosswalk width in each direction is $8$ ft and the number of pedestrians crossing during an interval is $22$ in the N$-$S direction and $34$ in the E$-$W direction. $($Assume the average speed of pedestrians is $3\mathrm{.}5$ ft$/$s$,$ and that it is feasible to disregard the yellow change and red clearance intervals.$)$
