Sub-problem 4b: Effect
of Unit Extension
In this exercise, we will consider the effect of the
extension variable on the overall operating characteristics of an
intersection controlled in an actuated mode.
Consider again the Styner-Lauder/U.S. 95 intersection that
is at the center of this case study. If you were going to evaluate the
operational effects of an actuated signal controller at this intersection,
it would be very important to select an appropriate unit extension for
the purposes of the analysis.
This sub-problem will help you address the following
issues, each of which is important to understand as you settle upon an
appropriate value for the unit extension variable:
