EXECUTIVE SUMMARY
INTRODUCTION
At the request of the City of Carmel and the Indiana Department of Transportation, A&F
Engineering has completed a comprehensive Traffic Impact Analysis on behalf of Duke
Construction. This analysis studied the traffic impacts that would result due to the
construction of a retail center that would be located between 98th Street and 106th Street
in Carmel, Indiana. The location of this site is graphically illustrated on a figure included
at the end of this document.
PURPOSE
The purpose of this Traffic Impact Analysis was to determine what effect traffic generated
by the proposed development, when fully occupied, will have on the existing adjacent
roadway system. The analysis identifies roadway deficiencies that may exist today or that
may occur when this site is developed. By identifying these existing or probable future
deficiencies, conclusions and recommendations are made in order to fix existing roadway
problems or too mitigate future traffic impacts caused by the traffic generated by the
proposed development.
In addition, the effects of a possible Commerce Drive extension to 96th Street were analyzed
in order to determine the effect this extension would have on future traffic patterns and
traffic volumes at each of the study intersections
ScoPE oF Wom~
The scope of work for this analysis was determined through a meeting between A&F
Engineering and the City of Carmel. The following outlines the scope of work for this
analysis:
o
The study area was defined to include the following intersections: A. Michigan Road & 96th Street
B. Michigan Road & Retail Parkway
C. Michigan Road & 106th Street
D. All Proposed Development Access Drives
.
A&F Engineering conducted peak hour traffic counts at each of the existing study
intersections.
o
A&F Engineering prepared an estimate of the AM & PM peak hour and 24-hour
traffic that would be generated l~y the proposed development. This traffic was
calculated per the ITE Trip Generation Manual.
.
A traffic signal warrant analysis was prepared at the intersection of Michigan Road
and the proposed development north access drive. This warrant analysis would
include the existing traffic volumes as well as the traffic volumes that would be
generated from the proposed development at full-build out. As part of this analysis,
a 24-hour traffic volume count on Michigan Road was collected by A&F
Engineering.
5. A Capacity Analysis and a Level of Service Analysis were conducted at each of the
study intersections for the following scenarios:
SCENARIO 1: Existing Conditions- Based on existing roadway
conditions and traffic volumes.
SCENARIO2A: Proposed Development without Commerce Drive
Extension - Add the traffic volumes that will be generated by the
proposed development to the existing traffic volumes. This scenario
will not consider a Commerce Drive extension to 96th Street and will
include direct access to the proposed development via three
Michigan Road access drives.
SCENARIO2B: Proposed Development without Commerce Drive
Extension (Limited Access) - Add the traffic volumes that will be
generated by the proposed development to the existing traffic
volumes. This scenario will not include a Commerce Drive
extension to 96th Street and will consider all MiChigan Road access to
be provided via the existing Retail Parkway only.
SCENARIO 3A: Proposed Development with Commerce Drive
Extension - Add the traffic volumes that will be generated by the
proposed development to the redistributed existing traffic volumes.
This scenario will consider a Commerce Drive extension to 96th
Street and will include direct access to the proposed development via
three Michigan Road access drives.
SCENARIO 3B: Proposed Development with Commerce Drive
Extension (Limited Access) - Add the traffic volumes that will be
generated by the proposed development to the redistributed existing
traffic volumes. This scenario will include a Commerce Drive
extension to 96th Street and will consider all Michigan Road access to
be provided via the existing Retail Parkway only.
SCENARIO4: Year 2014 Conditions - Project the existing traffic
volumes ten years forward using a 3 percent per year growth rate and
add generated traffic volumes from the development of near-by
vacant land not including the generated traffic volumes from the
proposed development.
SCENARIO5A: Year 2014 & Proposed Development without
Commerce Drive Extension -Add the traffic volumes that will be
generated by the.proposed development to the year 2014 traffic
volumes. This scenario will not consider a Commerce Drive
extension to 96th Street and will include direct access to the proposed
development via three Michigan Road access drives.
SCENARIO 5B: Year 2014 & Proposed Development without Commerce Drive
Extension -Add the traffic volumes that will be generated by the
proposed development to the year 2014 traffic volumes. This
scenario will not include a Commerce Drive extension to 96th Street
and will consider all Michigan Road access to be provided via the
existing Retail Parkway only.
SCENARIO 6A:
Redistributed Year 2014 & Proposed Development with Commerce
Drive Extension - Add the traffic volumes that will be generated by
the proposed development to the redistributed year 2014 traffic
volumes. This scenario will consider a Commerce Drive extension
to 96th Street and will include direct access to the proposed
development via three Michigan Road access drives.
SCENARIO 6B:
Redistributed Year 2014 & Proposed Development with Commerce
Drive Extension (Limited Access) - Add the traffic volumes that will
be generated by the proposed development to the redistributed year
2014 traffic volumes. This scenario will include a Commerce Drive
extension to 96th Street and will consider all Michigan Road access to
be provided via the existing Retail Parkway only.
o
The analysis techniques, conclusions and recommendations are described and
summarized in a Traffic Impact Analysis prepared by A&F Engineering. This
Executive Summary serves as a supplemental to the complete Traffic Impact
Analysis.
RESULTS
The following summarizes the results of the Traffic Impact Analysis.
Warrant Analysis
A warrant analysis was conducted at the intersection of Michigan Road and the proposed
development north access drive per the methods set forth in the Indiana Department of
Transportation Manual on Uniform Traffic Control Devices. This analysis showed that
when the proposed development traffic volumes are added to the existing traffic volumes,
the minimum traffic volumes set forth by Traffic Signal Criteria will be met.
Capacity Analysis/Level of Service Analysis
A capacity analysis and level of service analysis were conducted at each of the study
intersections for each the traffic scenarios discussed earlier. These intersections were
analyzed using Synchro traffic signal coordination software so that traffic operations
through the network would be optimized. The following tables summarize the level of
service results at each intersection.

All scenarios were analyzed with the proposed traffic signal control and the proposed
intersection geometrics that include the following:
1. The addition of a northbound right-turn lane along Michigan Road that
extends back through the middle and south access points. A recovery
taper is also proposed at the north access drive.
2. It is proposed that the southbound left-turn along Michigan Road have a
turn bay storage length no less than 300 feet with a 100 foot taper.
3. The proposed access constructed with two left-turn lanes and a shared
through/right-turn lane for outbound traffic and at least one lane for
inbound traffic.
CONCLUSIONS
The following conclusions are based on the results from the traffic signal warrant analysis
and the capacity/level of service analysis for all intersections within the study area.
Michigan Road & 96th Street
1. This intersection currently operates at level-of-service "C" during the AM peak
hour and level-of-service "D" during the PM peak hour.
o
The proposed Commerce Drive extension to 96th Street will allow some traffic to
by-pass this location. Thus, the proposed extension should improve furore traffic
operations at this intersection.
o
When furore background traffic is added, this intersection will operate at level-of-
service "F" during the PM peak hour. These operations will occur with or without
the addition of traffic from the proposed development.
Michigan Road & Retail Parkway
1. This intersection currently operates at acceptable levels of service during the peak
hours.
o
Vacant parcels exist near the existing Target superstore. This intersection will
serve as the primary drive for traffic generated by the development of these vacant
parcels.
o
Traffic volumes will significantly increase at this intersection if this drive is used
as the sole access for the proposed development. Traffic projections show that
when compared to the existing traffic volumes, the intersection volumes would
increase by approximately 20% with the Commerce Drive extension and
approximately 40% without the Commerce Drive extension above existing traffic
volumes if an additional access is not granted for the proposed development.
o
The proposed Commerce Drive extension to 96th Street will allow some traffic to
by-pass this location. Thus, the proposed should improve current and future traffic
operations at this intersection.
Michigan Road & 106th Street
1. This intersection currently operates at level-of-service "D" during the AM peak
hour and level-of-service "C" during the PM Peak hour.
2. The Indiana Department of Transportation is finalizing plans to reconstruct this
intersection within year 2005. When complete, the intersection will include the
following geometrics:
Northbound: One left-mm lane, two through lanes, one right-turn lane
Southbound: One left-mm lane, two through lanes, one right-turn lane
Eastbound: One left-mm lane, one shared through/right-turn lane
Westbound: One left-turn lane, one through lane, one right-turn lane
These improvements will provide a significant increase in intersection capacity.
Therefore, when the furore traffic volumes from the development of near-by
vacant land and from the proposed development are added to this intersection over
the next ten years, the operations at this intersection will be equal to or better than
what is experienced today.
3. The proposed Commerce Drive extension to 96th Street will allow some traffic to
by-pass this location. Thus, the proposed extension should improve furore traffic
operations at this intersection.
Michigan Road & Proposed Development North Access Drive
1. A traffic signal warrant analysis has Shown that a traffic signal will be warranted at
this location when the proposed development traffic volumes are added to the
roadway network.
.
When the proposed development and furore background traffic volumes are added
to the roadway network over the next ten years, this intersection will operate at
acceptable levels of service during the peak hours with the installation of a traffic
signal and with the recommended intersection geometrics.
o
A progression analysis model has shown that traffic progression could be
maintained along Michigan Road if a traffic signal were installed at this location in
order to serve the proposed development.
Michigan Road & Proposed Development Secondary_ Access Drives
1. The middle and south access points are proposed as 'right-in/right-out accesses.
This will allow left-mm movements in and out of the site to be performed only at
the signalized north access drive, thus creating a safe and efficient controlled
condition for left-turn vehicles entering and exiting the site.
RECOMMENDATIONS
Based on the analysis results and the conclusions, the following recommendations are made
to ensure that the traffic impacts associated with the proposed development are mitigated.
Commerce Drive Extension
Traffic projections and level-of-service calculations have shown that the proposed
extension of Commerce Drive would have a positive impact on traffic operations
along Michigan. Road by providing an alternate route to access the existing Target
development and any new development that might occur east of Michigan Road
between 96th Street and 106th Street. In addition, it is anticipated that a traffic signal
would most likely not be warranted in the near future at the intersection of 96th Street
and Conunerce Drive if the extension was constructed. However, the intersection
should be continually monitored as near-by development is constructed and additional
traffic is added.
Michigan Road & 96th Street
When the proposed development traffic volumes are added to the roadway network,
this intersection will operate at level-of-service "D" or better with the proposed
Commerce Drive extension. However, when the traffic volumes increase over ten
years due to background traffic growth, this intersection will operate at unacceptable
levels of service during the peak hours. The unacceptable peak hour operations will
occur with or without the proposed development.
Michigan Road & Retail Parkway
When the proposed development traffic volumes are added to the roadway network,
this intersection will operate at level of service "D" or better with the proposed
Commerce Drive extension. This occurs with or without direct access from the
proposed site to Michigan Road. However, when the traffic volumes increase over ten
years due to background and vacant land traffic growth, this existing intersection will
operate at unacceptable levels of service during the PM peak hour if direct access from
the proposed site to Michigan Road is not provided. Therefore, no improvements are
necessary at this intersection when direct access from the proposed site to Michigan
Road is provided.
Michigan Road & 106th Street
The Indiana Department of Transportation has future plans to begin reconstructing
this intersection within the year 2005 in conjunction with the widening of Michigan
Road. According to INDOT, this signalized intersection will be reconstructed to
include the following geometrics:
· Northbound: One left-mm lane, two through lanes, one right-turn lane
· Southbound: One left-mm lane, two through lanes, one right-turn lane
· Eastbound: One left-mm lane, one shared through/right-turn lane
Westbound: One left-turn lane, one through lane, one right-turn lane
The existing traffic signal control and the intersection geometrics planned by INDOT
will adequately serve the year 2014 traffic as well as the additional traffic generated by
the proposed site, with or without the proposed Commerce Drive extension.
Therefore, no improvements are necessary at this intersection above and beyond those
planned by INDOT.
Michigan Road & Proposed Development North Access Drive
The development of this drive would significantly reduce any future impact at Retail
Parkway due to additional traffic generated by the proposed development and any new
development within the area. In order to adequately serve the generated traffic from
the proposed development, a traffic .signal installation request for this access should be
made to the Indiana Department of Transportation in conjunction with the
development of the proposed site whether or not the proposed Commerce Drive
extension is constructed.
In addition to the installation of a traffic signal, the following intersection
conditions are recommended with or without the proposed Commerce Drive
extension:
· The addition of a northbound right-turn lane along Michigan Road that
extends back through the proposed middle and south access points. A
recovery taper is also proposed at the north access drive.
· It is recommended that the southbound left-turn along Michigan Road have a
turn bay storage length no less than 300 feet with a 1 O0 foot taper.
The proposed access constructed with two left-turn lanes and a shared
through/right-turn lane for outbound traffic and at least one lane for inbound
traffic.
Michigan Road & Proposed Development Secondary_ Access Drives
Proposed Middle Access- The following intersection conditions are recommended
with or without the proposed Commerce Drive extension'
1. It is recommended to construct this access as a right-in/right-out access
with one outbound lane and one inbound lane.
2. The addition of a northbound right-turn lane along Michigan Road that
extends back through the south access point.
Proposed South Access - The following intersection conditions are recommended
with or without the proposed Commerce Drive extension:
1. It is recommended to construct this access as a right-in/right-out access
with one outbound lane and one inbound lane.
2. The addition of a northbound right-turn lane along Michigan Road that
begins 100 feet south of the access and extends north through the middle
access to the north access drive.
