Traffic Stream Parameters:

Question $4)$A major road has $4$ lanes in each direction. The northbound capacity

is equal to $2615($veh$/$hr$/$lane$)$ and the free$-$flow speed

is $60$ mph$.$

$$ A$)$ What is the:

$-$Maximum flow rate$($qmax$)?$

$-$Maximum density$($kmax$)?$

$-$Jam density$($kj$)?$

$$ B$)$ If a one$-$hour vehicle count in the northbound direction for the outside

lane gives $6000$ vehicles in an uncongested condition, what is the estimated

mean speed of these $6000$ vehicles?
