Q$4$ Table APPENDIX A$.1$ shows traffic flow data, lane width and turning radius for each

approach at a signalized intersection that has two phases. The intersection is on level

ground, while the amber time, $a=3sec,$ all red interval, $R=2sec$ and driver reaction

time, $1=2$ sec$.$

$($a$)$ Complete Table APPENDIX A$\mathrm{.}1,$ and attach it in your answer seript.

$($b$)$ Sketch a timing diagram.

$($c$)$ Sketch a phase diagram.

$($d$)$ Give your comment if the intersection is on a gradient, has no All Red Time $($R$),$

and every movement increase at an annul rate of $5\%$ in next $5$ years.

Table APPENDIX A$\mathrm{.}1$: Traffic flow $($pcu$/$hour$),$ lane width $(m)$ and turning radius $(m)$

values for each phase and movement.
