Banks composed 6% and office space composed 4%. Despite being a large component of the overall shopping center, restaurants were not separated in the data analysis because the pedestrian count data did not separate between restaurant and non-restaurant volumes, thereby eliminating the possibility of developing reasonably accurate survey expansion factors for restaurant and non-restaurant trips.

(The Pointe was not surveyed; these internal trip-making estimates are based on values derived at the other two FDOT research sites and on observed balancing of trips into and out of the Village Commons uses.) Table 89 presents the distribution of trip origins for trips entering each of the surveyed Village Commons land uses: • None of the trips entering the office buildings onsite had an internal origin.

There was a steady stream of people going between the office building and that restaurant during the morning peak period. The other two developments each had similar restaurants; however, they had roughly 3 to 5 times the office space, they were several blocks away, and Atlantic Station's office building had a coffee stand in its lobby during the morning peak.

Weekday peak period internal capture rates are not appropriate for estimating weekend internal capture -- or weekday midday internal capture -- or daily internal capture unless survey data for those periods become available. Step 2: Define the Pertinent Site Characteristics In this step, the following data describing pertinent site characteristics are assembled: • The specific land uses in the mixed-use site in sufficient detail so that vehicle or person trip generation can be estimated for each individual land use (described in Steps 2A and 2B)
|
From page 97... ...
If specific land uses are not known at the time of analysis, use a more general category -- for example, at zoning, no specific retail categories may be known, so "shopping center" may be the best approximation. The nationally accepted method of estimating site trip generation is to use ITE Trip Generation report (2)

From page 98... ...
. Step 4A: Estimate Base Internal Capture Rates Internal trip capture rates are provided for land use pairs involving the following generic land use classifications: office, retail, restaurant, residential, hotel, and cinema.
|
From page 99... ...
Compare the MXD proximity to the proximity thresholds in the table: • If the proximity is less than or equal to the value in the third column of Table 107, use the unconstrained internal capture values in Table 105 or Table 106, whichever is appropriate. Remember that sub Table 7.1 values in Table 105 will be applied to the outbound trips; sub Table 7.2 values in Table 106 will be applied to inbound trips.

However, the data reported herein include only developments that satisfy the "mixed-use" definition used in this report. Mixed-Use Development Already in ITE Trip Generation Database In a typical shopping center that is included in the ITE Trip Generation report (2)
|
From page 101... ...
Current ITE land use classifications that already account for internal trip-making include the following: • Shopping center: shopping-center trip-generation rates are based on retail developments that already normally include restaurant, cinema, and limited other entertainment uses; however, "if a shopping center is planned to have out-parcel development of a significantly different land use classification or a very large percentage of overall gross leasable area, the site could be considered a mixed-use development for the purpose of estimating site trip generation" (1)
|
From page 102... ...
For those MXD sites or areas where all internal trips will be walked, bicycled, or driven onsite (on private internal streets or through parking areas) , the mode of access to the site should be used to factor vehicle external trip generation for the analysis period.
|
From page 103... ...
In the unlikely occurrence that the sum of internal trips should total over 100% of the total trip generation for a land use, it is recommended that the total internal trips be reduced to 100%, and the interchanges from the affected land use to other interacting land uses be proportionally reduced. This would not yield a total internal capture of 100 percent; rather, it would be one interchange and one direction that would be estimated to be 100%.
