INTRODUCTION
This TRAFFIC OPERATIONS ANALYSIS, prepared at the request of the City of Carmel on behalf of
Platinum Properties Management is for a proposed residential development known as Ambleside
Point that will be located south of the 146th Street Frontage Road and north of 141st Street east of
Towne Road in Carmel, Indiana.
PURPOSE
The purpose of this analysis is to determine what impact the traffic generated by the proposed
development will have on the existing adjacent roadway system. This analysis will identify any
existing roadway deficiencies or ones that may occur when this site is developed.
Conclusions will be reached that will determine if the roadway system can accommodate the
anticipated traffic volumes or will determine the modifications that will be required to the system if
there are identified deficiencies.
Recommendations will be made that will address the conclusions resulting from this analysis. These
recommendations will address feasible roadway system improvements to provide safe ingress and
egress, to and from the proposed development, with minimal interference to traffic on the public street
system.
SCOPE OF WORK
The scope of work for this analysis is as follows:
First, conduct traffic volume counts at the intersections of 141st Street & Beaument Boulevard and
141st Street & Autumn Woods Drive during peak hour periods.
Second, estimate the number of peak hour trips that will be generated by the proposed
development.
Third, assign and distribute the generated traffic volumes from the proposed development to the
study intersections.
Fourth, prepare recommendations for the roadway geometrics that will be needed to accommodate
the total traffic volumes once the proposed development is constructed.
Finally, prepare a TRAFFIC OPERATIONS ANALYSIS report documenting all data, analyses,
conclusions and recommendations to provide for the safe and efficient movement of traffic through
the study area.

DESCRIPTION OF THE PROPOSED DEVELOPMENT
The subject site is located south of the 146th Street east of Towne Road in Carmel, Indiana. The
proposed development will consist of approximately 50 town homes and 215 single-family homes.
As proposed, the site will be served by access drives along the 146th Street Frontage Road and two
access drives connecting to the existing Saddle Creek subdivision on Megan Drive and Beaument
Boulevard. Figure 1 is an area map showing the location and general layout of the proposed site.
STUDY AREA
The study area for this analysis has been defined to include the following intersections:
• 146th Street Frontage Road & Megan Drive
• 146th Street Frontage Road & Beaument Boulevard
• 141st Street & Autumn Woods Drive
• 141st Street & Beaument Boulevard
DESCRIPTION OF ABUTTING STREET SYSTEM
The proposed development will be primarily served by the public roadway system that includes
the following roadways:
146TH STREET FRONTAGE ROAD – is an east/west, two-lane undivided roadway with a posted speed
limit of 35 mph in the study area. According to the Carmel Thoroughfare Plan, 146th Street is
classified as a Local Street.
146TH STREET – is an east/west, four-lane divided roadway with a posted speed limit of 45 mph in the
study area. According to the Carmel Thoroughfare Plan, 146th Street is classified as a Primary Arterial
Street.
141ST STREET – is an east/west, two-lane undivided roadway with a posted speed limit of 40 mph in
the study area. According to the Carmel Thoroughfare Plan, 141st Street is classified as a Parkway
Collector Street.
TOWNE ROAD – is a north/south, four-lane divided roadway with a posted speed limit of 45 mph in
the study area. According to the Carmel Thoroughfare Plan, Towne Road is classified as a Parkway
Arterial Street.
DITCH ROAD – is a north/south, four-lane divided roadway with a posted speed limit of 45 mph in the
study area. According to the Carmel Thoroughfare Plan, Ditch Road is classified as a Parkway
Arterial Street.

EXISTING TRAFFIC VOLUMES & PEAK HOURS
A&F Engineering conducted traffic counts at the intersections of Beaument Boulevard & 141st Street
and at Autumn Woods Drive & 141st Street between the hours of 7:00 AM to 9:00 AM and 4:00
PM to 6:00 PM during a typical weekday in June 2020. According to the traffic counts, the AM
peak hours for the intersections occur from 7:45 AM to 8:45 AM. The PM peak hours for the
intersections occur from 5:00 PM to 6 PM and from 4:45 PM to 5:45 PM respectively. Figure 2
summarizes the peak hour traffic volumes for these intersections. The intersection count output
summary sheets for these counts are included in the Appendix.
GENERATED TRIPS FOR PROPOSED DEVELOPMENT
The estimate of newly generated traffic is a function of the development size and of the character
of the land use. The ITE Trip Generation Manual 1 was used to calculate the number of trips that
will be generated by the site. This report is a compilation of trip data for various land uses as
collected by transportation professionals throughout the United States in order to establish the
average number of trips generated by those land uses. Table 1 summarizes the total trips that will
be generated by the site.

PASS-BY & INTERNAL TRIPS
Pass-by trips are trips that are already in the existing traffic stream along the adjacent public roadway
system that enter a site, utilize the site, and then return to the existing traffic stream. Residential
developments do not typically attract a significant number of pass-by trips. Therefore, pass-by trip
reductions are not included in this study.
An internal trip results when a trip is made between two or more land uses without traversing the
external public roadway system. The proposed development is a single land use only. Hence, internal
trip reductions are not considered in this study.

ASSIGNMENT AND DISTRIBUTION OF GENERATED TRIPS
The study methodology used to determine the traffic volumes from the site that will be added to the
street system is defined as follows:
1. The volume of traffic that will enter and exit the site must be assigned to the access points
and to the public street system. Using the traffic volume data collected for this analysis,
traffic to and from the site has been assigned to the proposed driveways and to the public
street system that will be serving the site.
2. To determine the volumes of traffic that will be added to the public roadway system, the
generated traffic must be distributed by direction to the public roadways at their intersection
with the driveways. For the site, the trip distribution was based on the location of the
development, the existing traffic patterns, and the assignment of generated traffic.
Figure 3 illustrates the assignment and distribution of generated traffic volumes for the proposed
development.
GENERATED TRIPS ADDED TO THE STREET SYSTEM
The total generated traffic volumes that can be expected from the proposed development have been
assigned to each of the study intersections. These volumes were determined based on the
previously discussed trip generation data, assignment of generated traffic and distribution of
generated traffic. Figure 4 displays the peak hour traffic volumes for the proposed development.
In addition, Figure 5 shows the sum the existing traffic volumes and the volumes generated by
the proposed development.
CONCLUSIONS & RECOMMENDATIONS
Based on the previously mentioned assignment and distribution of generated traffic volumes, and
the resulting traffic volumes; the generated traffic from the proposed development will have
minimal impact on the adjacent roadway system.
