TRAFFlC IMPACT ANALYSIS
DESCRIPTION OF THE ABUTTING STREET SYSTEM
This proposed development will be served by the public roadway system that includes 1-465, U.S.
31, 96th Street, College Avenue, Westfield Boulevard and Real Road.
IN1ERSTATE 465 - is a major Interstate loop that surrounds the greater Indianapolis metropolitan
area.
MERIDIAN SlREET/U.S. 31 - is a north-south, four-lane divided highway that runs the entire
length of Indiana and serves as a major arterial to several mid-size cities throughout the state.
This roadway becomes Meridian Street within the Indianapolis City limits.
96m SlREET - is an east-west, two-lane roadway that runs from Michigan Road to Keystone
Avenue. This street becomes a four-lane facility at Keystone Avenue and continues east to 1-69.
WESTFIELD BOULEVARD - is a north-south, two-lane roadway that provides access to several
residential areas throughout Marion County and Hamilton County.
9(/h Street & U.S. 31 - This intersection is controlled by a full actuated traffic signal. The
northbound approach consists of an exclusive left-turn lane, a shared through/right-turn lane and
three through lanes. The southbound approach consists of two exclusive left-turn lanes an
exclusive right-turn lane and three through lanes. The westbound approach consists of an
exclusive left-turn lane, an exclusive right-turn lane and a through lane and the eastbound
approach consists of an exclusive left-turn lane, a shared right-turn/through lane and a through
lane.
9(/h Street & College Avenue - This intersection is controlled by a full actuated traffic signal. All
approaches at this intersection consist of an exclusive left-turn lane and a shared right-
turn/through lane.
Real Road & Westfield Boulevard - This "T" -intersection is currently stop controlled with Real
Road stopping for Westfield Boulevard. In the near future a traffic signal will be installed at this
location.
TRAFFIC DATA
Peak hour manual turning movement traffic volume counts and 24 hour volume counts were made
at the study intersections and along 96th Street by A&F Engineering Co., LLC. The traffic turning
movement counts include an hourly total of all "through" traffic and all "turning" traffic at thee

TRAFFlC IMPACT ANALYSIS
CONCLUSIONS
The conclusions that follow are based on existing traffic volume data, trip generation, assignment
and distribution of generated traffic, capacity analyses with the resulting levels of service that have
been prepared for each of the study intersections, and the field review conducted at the site. These
conclusions apply only to the AM Peak Hour and PM Peak Hour that were addressed in this
analysis. These peak hours are when the largest volumes of traffic will occur. Therefore, if the
resulting level of service is adequate during these time periods, the remaining 22 hours will have
levels of service that are better than the peak hour, since the existing street traffic volumes are less
during the other 22 hours.
1. 96TII SlREET AND MERIDIAN SlREET
Existing (Scenario 1) - A review of the level of service for each of the intersection
approaches, with the existing traffic volumes and existing geometries, has shown this
intersection is operating at acceptable levels during the AM Peak Hour and the PM Peak
Hour.
Year 2011 (Scenario 2) - With the traffic volumes from the vacant lands and the
background traffic through the Year 2011 added to the existing traffic volumes, this
intersection will operate at acceptable levels during the AM Peak Hour and below
acceptable levels of service per the City of Carmel Guidelines during the PM Peak Hour
with the proposed intersection geometries. The proposed geometries are illustrated on
Figure 7.
Proposed Development (Scenario 3) - When the traffic volumes from the proposed
development are added to the existing, Year 2011, and vacant land traffic volumes, this
intersection will operate below acceptable levels with the proposed geometrics outlined in
the Year 2011 scenario. These proposed geometrics are illustrated on Figure 7.

- 7. 96TH SlREET AND EAST ACCESS POINT
Proposed Development (Scenario 3) - When the traffic volumes from the proposed
development are added to the existing, Year 2011, and vacant land traffic volumes all
approaches at this intersection will operate at acceptable levels with the proposed
intersection geometrics. The proposed intersection geometries are illustrated on Figure 11.
RECOMMENDATIONS
Based on this analysis and the conclusions, the following recommendations are made to ensure that
the roadway system will operate at acceptable levels of service if the site is developed as proposed.
1. 96TII SlREET AND MERIDIAN SlREET
· This intersection should be reconstructed to include the geometries illustrated on Figure 7.
These improvements should be constructed based on future vacant land traffic and are not solely
a result of the proposed development.
2. 96TII SlREET AND COLLEGE AVENUE
· This intersection should be reconstructed to include the geometries illustrated on Figure 8.
These improvements should be constructed based on future vacant land traffic and are not solely
a result of the proposed development.
3. REAL ROAD AND WESlFIELD BOULEY ARD
· A traffic signal is planned at this intersection early in the Year 2001. Furthermore, a left-turn
and right-turn lane should be constructed along the eastbound approach as traffic increases due
to the proposed development and surrounding vacant lands. The proposed future improvements
are illustrated on Figure 9.
4. 1-465 EASTBOUND OFF-RAMP AND MERIDIAN SlREET
· Due to the large amount of traffic exiting 1-465 and along Meridian Street, this intersection
might experience delays during the AM Peak Hour. These delays will occur independently of
the proposed development as traffic increases over time and as traffic is generated from vacant
land development.
· The Indiana Department of Transportation has future plans for the modification of this
interchange. However, before these improvements are made, an eastbound right-turn lane
should be constructed to better serve the eastbound to southbound exiting vehicles. These
improvements are shown on Figure 10.
