Problem 2: Reitz
Union Drive Intersection Improvement Strategies
Using this data to
work through the HCM procedures will yield for each movement and approach:

capacity 

v/c ratio 

queue
storage ratio 

delay 

level
of service 
Results of our analysis, including overall intersection delay and level of
service, are shown in the following table:

Remember, since the HCM methodology assumes all
lanes have adequate storage when computing delay, you must check the
backofqueue and queue storage ratio for each lane group to determine if
there are queue storage problems. (A queue storage ratio greater than 1.0
indicates estimated queues are greater than available storage).
With this analysis of the existing conditions at the Reitz
Union Drive intersection, we will address intersection improvement
strategies in the ensuing subproblems.
