$1$ Terminology and Lost Time $[10$ points$]$

The chart below shows the signal timings $($in seconds$)$ for a three phase signal. Determine and show on

the chart the following:

The cycle time, $C$

The change and clearance interval for Phase $B$

The red clearance interval, $R_C,$ for Phase A

The total lost time, $L.$ You may assume the startup lost time, $l_1,$ is $2\mathrm{.}0sec$ and the green

extension, $e,$ is $2\mathrm{.}0sec$ as well.Homework $5$ Signal Timing $1$ Yellow Time $[7$ points$]$ Vehicles traveling along the north$-$south approach must cross an east$-$west roadway $48$ ft wide. Assuming a design speed of $30$ mph along a level road, determine the appropriate length for the yellow interval. Assume the average vehicle length is $20$ ft$,$ and the perception$-$reaction time is $1\mathrm{.}0$ sec$.$ Use the AASHTO recommended deceleration rate of $11\mathrm{.}2$ ft $/$ sec$^2.2$ Terminology and Lost Time $[8$ points$]$ The chart below shows the signal timings $($in seconds$)$ for a three phase signal. Determine and show on the chart the following: $1.$ The cycle time, C $2.$ The change and clearance interval for Phase B $3.$ The red clearance interval, R$\_$C$,$ for Phase A $4.$ The total lost time, L$.$ You may assume the startup lost time, l$\_1,$ is $2\mathrm{.}0$ sec and the green extension, e$,$ is $2\mathrm{.}0$ sec as well.
