Re: Traffic Impact Analysis Addendum
Weston Communities
Introduction
This is an addendum to the Traffic Impact Analysis that was
prepared for the Carmel/Clay Plan Commission regarding the primary
plat proposal for Weston Communities. The Traffic Impact Analysis
included an analysis of several vacant parcels that are anticipated
to be developed within the time frame -of this analysis. However,
the study did not review the impact that Hunter Field, when fully
completely develop, and Linkside, if developed, would have on the
roadway system that is outlined in the original analysis.
This addendum is an analysis of the traffic volumes that could be
generated by the Hunter Field and Linkside developments. These
volumes have been added to the traffic volumes from the original
analysis. A recalculation of the levels of service were made for
the intersection of Michigan Road and 106th Street and the
intersection of Shelborne Road and 106th Street.
Generated Traffic Volumes
The generated traffic volumes from both the Linkside development
and the Hunters Field Development are shown on Figure 1. The
volumes were assigned to the roadway system based on existing
traffic counts within the area. Also taken into consideration in
the assignment of traffic was the proximity of each development to
Michigan Road, 96th Street and 116th Street.

Total Traffic Volumes
The generated traffic volumes from both the Linkside Development
and Hunter Field Development were added to the sum of the existing
traffic volumes, year 2004 traffic volumes, vacant land traffic
volumes and the proposed Weston Communities development. Figure 2
is a summary of these traffic volumes at the study intersections.
Capacity Analysis
In order to evaluate the added traffic from the additional
developments a level of service calculation was conducted at each
of the study intersections. The tables that follow are a summary
of the results for each scenario.
CONCLUSIONS
Based on the various capacity analyses it has been determined that
level of service will remain at acceptable levels for all of the
study area intersections. The additional traffic generated by a
fully occupied Hunter Field development and Linkside development
will not reduce the level of service at any of the study
intersections. The additional capacity analyses are attached to
the back of this addendum.
