Question $(3)(3\mathrm{.}0$ points$)$

A segment of two$-$lane highway has the following roadway characteristics:

Passing constrained in the analysis direction

Segment Length $(L)=3,960ft$

Level Terrain $($Vertical Class $1)$

$FFS=62\mathrm{.}7m\frac{i}{h}($based on posted speed limit of $55m\frac{i}{h})$

For these conditions, determine the follower density for an analysis direction flow rate $(v_d)$ of $800ve\frac{h}{h}($this accounts for the measured hourly volume and the PHF$)$ that consists of only passenger cars
