    2b: What are the Levels of Service 
    in the Weaving Sections Located in the I-87/Alternate Route 7 Interchange? The New York State Department of Transportation has a 
    program of continuous traffic counting for most freeways and highways in the 
    state. Data gathered from the permanent count stations located on the 
    interchange were used to identify the morning and afternoon peak hour for 
    the entry and exit points at the weaving sections, identified as points A, 
    B, C, and D in Exhibits 4-24, 4-25, and 4-26 below. From these entry and exit counts, 
    local traffic engineers estimated the origins and destinations for the 
    weaving sections based on their knowledge of local traffic flow conditions. Sometimes you will have actual origin-destination movements for a weaving 
    section, but other times, as for this sub-problem, you will need to estimate 
    the weaving flows based on your knowledge of local conditions. Exhibit 4-23 shows the origin and destination data that 
    were estimated for the three weaving sections.
