Sub-problem 3c: Critical Movement Analysis
In sub-problem 3b, we saw how we can use a microscopic simulation model to
address conditions in which demand exceeds capacity. The model produces
detailed statistics on the performance of the U.S. 95/Styner-Lauder Avenue
intersection under these conditions. We'll now see in this sub-problem
that we can use a much simpler approach, critical movement analysis, to
determine whether the demand will exceed capacity for this intersection during
the high volume conditions present after football games at the University of
Idaho.

What is critical movement analysis? |
|
What data are needed to conduct critical movement
analysis? |
|
What outputs are produced by critical movement
analysis? |
|
Are the results from critical movement analysis any
more or less valid than the results produced by the HCM or by microscopic
simulation models? |
|
Why is there virtually no difference
between estimated delay on the eastbound and westbound approaches to the
intersection? |
|
What is the effect of grade and heavy
vehicles? |
|
How do changes in vehicle mix affect the intersections
when the intersection operates near or at capacity? |
|
What effects do heavy vehicles have on the intersection
beyond changes to saturation flow rate? |
Take a few minutes
to consider these issues before we proceeding with this
analysis.
