A &F ENGINEERING CO., INC. Steven J. Fehribach, P.E. Indiana Registration 890237 Thomas S. Vandenberg, E.I. Transportation Engineer TRAFFIC OPERATIONS ANALYSIS CLARIAN HEALTH TRAFFIC OPERATIONS ANALYSIS INTRODUCTION This TRAFFIC OPERATIONS ANALYSIS, prepared at the request of the Carmel Department of Community Services on behalf of Clarian Health, is for a proposed multi -use site that will be located in the northwest quadrant of the intersection of U.S. 31 116t Street. PURPOSE The purpose of this analysis is to determine what effect traffic generated by the proposed development, when fully occupied, will have on the existing adjacent roadway system. This analysis will identify any roadway deficiencies that may exist today or 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 it is determined there will be deficiencies in the system resulting from the increased traffic volumes. Recommendations will be made that will address the conclusions resulting from this analysis. These recommendations will address feasible roadway system improvements which will accommodate the proposed development traffic volumes such that there will be 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: First, to make traffic volume counts at the following locations: U.S. 31 116 Street 116 Street Spring Mill Road Existing Drives along 116 Street Second, to estimate the number of new trips that will be generated by the proposed development. Third, to assign the generated traffic volumes to the driveways and/or roadways that will serve to provide access to the proposed development. 1 1 1 1 CLARIAN HEALTH TRAFFIC OPERATIONS ANALYSIS Fourth, to distribute the generated traffic volumes from the proposed development onto the public roadway system and intersections that have been identified in the study area. Fifth, to prepare an analysis including a capacity analysis and level of service analysis for each intersection included in the study area for each of the following scenarios: SCENARIO 1: Existing Traffic Based on existing roadway conditions and traffic volumes. SCENARIO 2: Existing Traffic with Parcel 1 -A (Includes Clarian Hospital) Add the traffic volumes that will be generated by Parcel 1 -A of the proposed development to the existing traffic volumes. SCENARIO 3: Year 2013 Traffic Project the existing traffic volumes ten years forward using a growth rate. This scenario also takes into consideration the proposed interchange configuration of 116 Street U.S. 31. SCENARIO 4: Year 2013 Traffic with Proposed Development Add the traffic volumes that will be generated byy all parcels of the proposed development to the projected year 2013 traffic volumes. This scenario also takes, into consideration the proposed interchange configuration of 116 Street U.S. 31. Finally, to prepare a TRAFFIC OPERATIONS ANALYSIS documenting all data, analyses, conclusions and recommendations to provide for the safe and efficient movement of traffic through the study area. DESCRIPTION OF THE PROJECT The proposed development will be located in the northwest quadrant of U.S. 31 and 116 Street in Carmel, Indiana. Table 1 summarizes the proposed land uses and approximate size of each use. In addition, Figure 1 is an area map of the site that shows the location of each proposed use. 2 CL'ARIAN HEALTH Figure 1 shows an approximate location of the proposed Illinois Street. 3 TRAFFIC OPERATIONS ANALYSIS PROPOSED ILLINOIS STREET It is planned by the City of Carmel that a proposed four -lane divided Illinois Street be constructed between Spring Mill Road and U.S. 31 and will run north/south from 96 Street to 136 Street. For purposes of this study, the following scenarios will be analyzed with the proposed Illinois Street: SCENARIO 2: Existing Traffic with Parcel 1 -A (Includes Clarian Hospital) SCENARIO 3: Year 2013 Traffic SCENARIO 4: Year 2013 Traffic with Proposed Development CLARIAN HEALTH TRAFFIC OPERATIONS ANALYSIS STUDY AREA The study area defined for this analysis will include the following intersections: 116 Street U.S. 31 116`'' Street Spring Mill Road All Proposed Access: Points along Spring Mill Proposed South Hospital Access along Illinois Street Proposed North Hospital Access along Illinois Street. DESCRIPTION OF THE ABUTTING STREET SYSTEM This proposed development would be served by the public roadway system that includes U.S. 31, 116 Street and Spring Mill Road. 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. 116 STREET is an east -west roadway that serves many residential and commercial areas throughout southern Hamilton County. The posted speed limit along this roadway in the vicinity of the site is 40 mph. SPRING MILL ROAD is a north- south, 2 -lane roadway that serves many residential areas throughout Hamilton County.= The posted speed limit along this roadway in the vicinity of the site is 40 mph. U.S. 31 116 Street. This. intersection is currently controlled with 'an automatic traffic signal. The existing intersection geometrics are illustrated on Figure 2. The Indiana Department of Transportation is currently conducting an Environmental Impact Study (EIS) to determine if an interchange is feasible at this intersection. 116 Street Spring Mill Road This intersection is currently controlled as a four -way stop. The existing intersection geometries are illustrated on Figure 2. The Hamilton County Highway Department has future plans to construct a roundabout at this location. TRAFFIC DATA Peak hour manual turning movement traffic volume counts were made at each of the study intersections by A &F Engineering Co., LLC. The traffic volume counts include an hourly total of all "through" traffic and all "turning" traffic at the intersection. The traffic volume counts were made during the hours of 6:00 AM to 9:00 AM and 3:00 PM. to 6:00 PM in December 2002 January 2003. These counts are included in Appendix A. 5 DEVELOPMENT INFORMATION GENERATED TRIPS PARCEL LAND USE ITE CODE SIZE AM ENTER AM EXIT PM ENTER PM EXIT 1A Hospital 610 374,732 SF 273. 101 87 277 Medical Office 720 156,058 SF 303 76 154 417 1B Medical ,Office 720' 200,000 SF 389 97 198 534 2B Nursing Home 620 100 Rooms 12 8 6 8 2C Medical Office 720 100,000 SF 194. 49 99 267 2D Hotel 310 200 Rooms 59 38 56 50 Retail 820 150,000 SF 124 79 394 427 2E Retail 820 75,000 SF 82 52 249 270 1 1 1 1 1 1 1 1 1 1 1 1 CLARIAN HEALTH. TRAFFIC OPERATIONS ANALYSIS PEAK HOUR The peak hour is based on the traffic volume counts collected at the study intersections. The peak hour varies by intersection. Throughout this analysis, all references to the peak hour will be for the peak hour at the individual intersections to represent the "worst case" scenario. GENERATED TRAFFIC VOLUMES FOR PROPOSED DEVELOPMENT The estimate of traffic to be. generated by the proposed development is a function of the development size and of the character of the land use. Trip Generation report was used to calculate the number of trips that will be generated by the proposed development. 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 various land uses. Table 1 summarizes the trips that will be generated by the proposed development. TABLE 1 GENERATED TRIPS FOR PROPOSED DEVELOPMENT PASS -BY TRIPS Pass -by trips are trips already on the roadway system that decide to enter a land use. The retail uses within the proposed development will generate pass -by trips. Therefore, the pass -by trips percentages published in the Trip Generation Handbook have been applied. Table 2 summarizes the pass -by trip reductions.

Internal trips typically occur in mixed -use developments. The proposed development will have a mix of land uses. Therefore, an internal trip reduction published in Transportation and Land Development has been applied. Table 2 summarizes the internal trip reduction. 3 Transportation and Land Development, Instit of Transportation Engineers, 1988.

Road 2.5 per Year 1 CLAIUAN'HEALTH TRAFFIC OPERATIONS ANALYSIS ANNUAL GROWTH RATE FOR BACKGROUND TRAFFIC In order to forecast future background traffic volumes, annual growth rates were determined on a street by street basis. Table 3 summarizes the annual growth rate used on each study roadway. TABLE 3 ANNUAL GROWTH RATES FOR BACKGROUND TRAFFIC ASSIGNMENT AND DISTRIBUTION OF GENERATED TRIPS The study methodology used to determine the traffic volumes, fromthe proposed development, that will be added to the streetsystem is defined as follows: 1. The volume of traffic that will enter and exit the site must be assigned to the various access points and to the .public street system. Using the: traffic volume data collected for this analysis, traffic to and from the proposed new 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 driveway. For the proposed development, the distribution was based on the existing traffic patterns and the assignment of generated traffic. Two separate assignment and distribution designations were made for the proposed development, one for just 1 -A (includes:Clarian Hospital) and another for all of the parcels. In addition, the assignment and distribution for all parcels of the development is split by land use type. All medical and hotel land uses have an assignment and distribution while, all retail land uses have another assignment and distribution. The'foliowing figures show the different assignment and distributions: CLARIAN HEALTH TRAFFIC OPERATIONSANALYSIS Figure 3 Assignment and Distribution of Generated Traffic Volumes for Parcel 1 -A (Includes Clarian Hospital) Figure 4A Assignment and Distribution of Generated Traffic Volumes for all Medical and Hotel' Land Uses Figure 4B Assignment and Distribution of Generated Traffic Volumes for all Retail Land Uses '(Non Pass -By) Figure A in Appendix A shows: the assignment and distribution for the pass -by generated traffic of the retail land uses. PROPOSED DEVELOPMENT GENERATED TRIPS ADDED TO THE STREET SYSTEM Generated traffic volumes that can be expected from the proposed development have been prepared for each of the proposed access points and for each of the study area intersections. These data are based on the previously discussed trip generation data; assignment of generated traffic, and distribution of generated traffic. Two separate assignment and distribution designations were made for theproposed development, one for justParcel 1 -A (includes Clarian Hospital) and another for all of.the parcels. In addition, the assignment and distribution for all parcels of the development: is split by land use type. All medical and hotel land uses have an assignment and distribution while all retail land uses have another assignment and distribution. The peak hour generated traffic volumes for the development are shown on the following figures: Figure 5 Generated Traffic Volumes for Parcel 1 -A (Includes Clarian Hospital) Figure 6 Total Generated Traffic Volumes for Proposed Development The following figures in Appendix A show peak hour generated traffic volumes separately for the proposed development: Figure B Generated Traffic Volumes for All Retail Land Uses (Pass -By) Figure C Generated Traffic Volumes for All Medical Hotel Land Uses Figure D Generated Traffic Volumes for All Retail Land Uses (Non Pass -By) 1 0 CLARIAN i3EAi.TH TRAFFIC OPERATIONS ANALYSIS EXISTING TRAFFIC VOLUMES Existing traffic volumes obtained from the traffic counts are shown on Figure 7. REDISTRIBUTED EXISTING TRAFFIC VOLUMES There are currently two drives on the south side of 116 Street between U.S. 31 and the proposed Illinois Street that serve access to existing development. It is proposed that the west drive be removed and the east drive will be converted to a right in/right out access. In addition, a drive will be 'constructed along the south leg of the proposed Illinois Street to serve access to the existing development. Volumes entering and exiting the drive will need to be redistributed, throughout the system in order to account for these changes. The following figures in Appendix A show the redistributed existing traffic volumes: Figure E Year 2003 Redistributed Existing Traffic Volumes Volumes (Considering Drives Along 116 Street) Figure F Year 2013. Redistributed Existing Traffic Volumes Volumes (Considering Drives Along 1l6 Street) ANTICIPATED TRAFFIC VOLUMES FOR PROPOSED I LLINOIS STREET Figure G in Appendix A shows the anticipated traffic volumes at the intersection of 116 Street and Proposed Illinois Street due to the construction of the proposed Illinois Street. YEAR 2013 TRAFFIC VOLUMES To evaluate the future impact of the proposed development on the public roadway system, the redistributed existing traffic volumes must be projected forward to a design year The design year used for this project will be year 2013. The year 2013 .(redistributed) projected traffic volumes are shown on Figure 9. 11 CLARIAN HEALTH TRAFFIC OPERATIONS ANALYSIS CAPACITY ANALYSIS The "efficiency" of an intersection is based on its ability to accommodate the traffic volumes that approach the intersection. The "efficiency" of an intersection is designated by the Level -of- Service (LOS) of the intersection. The LOS of an intersection is determined by a series of calculations commonly called a "capacity analysis Input data into a capacity analysis include traffic volumes, intersection geometry, number and use of' lanes and, in the case of signalized intersections, traffic signaln tirning. To determine the level of service at each of the signalized and unsignalized study intersections, a capacity analysis has been made using the recognized computer program Synchro4. The recognized computer program aaSIDRA was used to determine the level of service at each of the roundabouts. DESCRIPTION OF LEVELS OF. SERVICE The following descriptions are for_signalized intersections: Level of Service A describes operations with a very low delay, less than or equal to 10.0 seconds per vehicle. This occurs when progression is extremely favorable, and most vehicles arrive during the green phase. Most vehicles do not stop at "all. Level of Service B describes operations with delay in the range of 10.1 to 20.0 seconds per vehicle. This generally occurs with good progression. More vehicles stop than LOS A, causing higher levels of average delay. Level of Service C describes operation with delay in the range of 20.1 seconds to 35.0 seconds per vehicle. These higher delays may result from failed progression. The number of vehicles stopping is significant at this level, although many still pass through the intersection without stopping. 4 Synchro 5.0, Trafficware, 2001. 5 aaSIDRA 2.0, Akcelik Associates, 2000. 17 CLARIAN HEALTH TRAFFIC OPERATIONS ANALYSIS Level of Service D Level of Service E describes operations with delay in the range of 35.1 to 55.0 seconds per vehicle. At level of service D, the influence of congestion becomes more noticeable. Longer delays may result from some combinations of unfavorable progression. Many vehicles stop, and the proportion of vehicles not stopping declines. describes operations with delay in the range of 55.1 to 80.0 seconds per vehicle. This is considered to be the limit of acceptable delay. These high delay values generally indicate poor progression and long cycle lengths. Level of Service F describes operations with delay in excess of =80.0 seconds per vehicle. This is considered to be unacceptable .to most drivers. This condition often occurs with oversaturation, i.e., when arrival flow rates exceed the capacity of the intersection. Poor progression and long cycle lengths may also be major contributing causes to such delay levels. The following list shows the delays related to the levels of service for unsignalized intersections: Level of Service. A B C D E F 18 Control Delay (seconds /vehicle) Less than or equal to 10 Between 10.1 and 15 Between 15.1 and 25 Between 25.1 and 35 Between 35.1 and 50 greater than 50 CLARIAN HEALTH TRAFFIC OPERATIONS ANALYSIS CAPACITY ANALYSES SCENARIOS To evaluate the proposed development's effect on the public street system, the traffic volumes from each of the various parts must be added together to form a series of scenarios that can be analyzed. The analysis of these scenarios determines the adequacy of the existing roadway system. From the analysis, recommendations can be made to improve the public street system so it will accommodate the increased traffic volumes. An analysis has been made for the AM peak hour and PM peak hour for each of the study intersections for each of the following scenarios: SCENARIO 1: Existing Traffic Volumes These are the traffic volumes that were obtained in December 2002 January 2003. Figure 7 is a summary of these traffic volumes at the study intersections. SCENARIO 2: Existing. Traffic Volumes Parcel 1-A Traffic Volumes (Includes Clarian Hospital) Figure 8 is a summary of these traffic volumes at the study intersections for the peak hour.

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, it can generally be assumed the remaining 22 hours will have levels of service that are better than the peak hour, since the existing street traffic volumes will be less during the other 22 hours. 1. 116 STREET U.S. 31 Scenario 1 Analysis: Existing Traffic Volumes Scenario 1 Results: This intersection is currently operating under acceptable levels of service during the peak hours with the existing intersection geometrics and existing traffic signal.
