The freeway shown below has $12-$foot lanes, adequate lateral clearances, level terrain, and is used

primary by commuters. The freeway also has an interchange density of $2$ interchanges per mile.

What is the level of service of Ramp B$?($Reminder: The freeway volume given is the volume

upstream of Ramp A$.$ The freeway volume for Ramp B should be adjusted to reflect vehicles

entering at Ramp A$).$

Please Note:

The lecture notes and recording uses the notation and equation from the $4^{th}$ edition of the text.

The methodology for the $4^{th}$ and $5^{th}$ edition of the text remains the same with the following

exceptions. Please use the demand flow calculation and heavy vehicle calculation as used in the

$5^{th}$ edition.

$**$Ldn or Ldown $-$ distance from study ramp to downstream ramp

$***$ LD $-$ deceleration lane length
