Cyntheanne Road Transportation Planning Study - Indianapolis ...

2.1.4 Projected Traffic Volumes & Level of Service Summary
Future peak hour traffic volumes were provided by A&F Engineering for
2022. The new Cyntheanne Road traffic volumes were reassigned to the
three alternative routes and the increase in cumulative traffic has been
studied. A summary of the data is shown for each alternative route in the
Appendix.
The future traffic demand along Cyntheanne Road shows a significant
increase in travel because of new developments planned along the
corridor. This increase in demand required further study to determine if
the current roadway design has enough capacity to handle this additional
traffic safely and efficiently. Based on the existing roadway conditions and
design, both capacity and geometric improvements will be required.
Specific design details are discussed in the Alternatives Section.
Level of Service (LOS) was reviewed at all of the intersections along the
three routes to determine the current operating capacity of each
intersection. LOS ratings have been developed to rank the effectiveness of
roadways and intersections at accommodating the volume of traffic that
travels along them. Since traffic volumes are currently below capacity, the
existing level of service is at a “B” level or better, which indicates minimal
delays. As traffic volumes increase in the future, the intersection
congestion increases and LOS ratings will drop to C, D or E. LOS C and D
are characterized by congestion and continuous lines of vehicles waiting at
intersections. LOS E represents a failure of the transportation system to
accommodate the vehicles using it, which results in heavy congestion and
stopped traffic. Deteriorating LOS ratings can be overcome with proper
intersection design and potential signalized improvements. All upgraded
intersections could operate at acceptable service levels with a two-lane
roadway with these design improvements. The LOS results were obtained
from A&F Engineering provided in the report “Traffic Impact Fee
Analysis” from December 2004.
2. 2 Land Use
The land use on Cyntheanne Road is primarily agricultural land and natural
areas. The future land use of the south section of Cyntheanne Road (96 th Street
to Connecticut Avenue) is currently projected to be primarily residential
developments while the north section (I-69 to SR 238) is to be developed as
single family residential and small commercial development. The north section
also plans to include a recreational park between SR 238 and 126 th Street.
