The signals af the intersections along the two$-$way street have been pretimed as shown below $($all the timings

in secends$),$ Civen that the speed is $48\mathrm{.}6k\frac{m}{h}r(13\mathrm{.}5\frac{m}{s}),$ determine the width $($if any$)$ of the through bands

in each of the two dreerions, itarther determine the maximum through$-$band width for traffic moving from

intersection A to D by modifying the offset. Also determine the revised through$-$band width $($if any$)$ for traffic

moving in opposite direction $($from D to A$)$ with the modified offset.
