Link Volume Factor Method (Cont’d)
►Caveats
The final project trips after the ITE trips have been
factored by the link distribution percentages are not
consistent with the modeled trip generation.
Resulting trip tables do not match ITE trips.
Modeled capacity constraints may not be consistent
with ITE project trips. This means that project
traffic may not be accurately impacted by
congestion during highway assignment.

Link Volume Factor Method (Cont’d)
►Caveats (Cont’d)
Socioeconomic data must be estimated by applying
rates to data typically provided by the developer.
These estimates may not accurately reflect the real
development pattern of the site.
Also, developer-provided provided data are typically not
complete from a modeling perspective, requiring
the analyst to make assumptions based on existing
model data.
