FSUTMS Comprehensive Modeling Workshop - Cambridge ...

Special Generators
► Special generators may be required when normal
generation equations produce too much or too few
productions or attractions than expected for a trip
purpose for a particular TAZ.
► Adjustments may be necessary if the trip generation
rates applied to the socioeconomic data do not produce
the correct number of trip ends.
For example: parks and beaches normally have few
workers and would produce very few attractions based
on employment … By computing a value for the TAZ
from some other source, the planner can correctly
estimate attractions for HBSR trips.
