An intersection has a three$-$phase signal with the movements allowed in each phase and corresponding analysis and saturation flow rates shown in the following Table. Assume the lost time is $4$ seconds per phase and a critical intersection v$/$c of $0\mathrm{.}90$ is desired. Calculate the overall intersection average delay $($using Eqs. $1-3$ mentioned below$)$ and level of service.
