For the proposed zoning, B -2, the most intense land use with regards to traffic impact would be general retail. Therefore, data was generated for this use and an additional analysis was completed for retail land use. The attached figures show the generated traffic for general retail and the anticipated total traffic volumes for both the driveway and intersections. The analysis has shown that the driveway traffic has increased with the use of retail as a land use. Based on the generated traffic for general retail, the recommendation should now include the installation of a passing blister along 136th Street for eastbound traffic. However, if the site is developed as proposed with a light store and paint /hardware stores, then a passing blister is not warranted. This passing blister will ensure the free flow of traffic from U.S. 31 past the proposed driveway. This supplemental analysis along with the original report has shown that the retail land use will not negatively affect the surrounding street system if the recommendations are installed as advised. 5172 EAST 65TH STREET INDIANAPOLIS, INDIANA 46220 — TELEPHONE (317) 8420864 FACSIMILE (317) 849.6816 10. 12. 95 04:18 FM 202 JAMES J.

PURPOSE This analysis is to determine what effect traffic generated by the proposed development, when fully occupied, will have on the existing adjacent roadway system. Recommendations based on the findings will be made to provide for the 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 new traffic volume counts at the following locations: 1. 131st Street and Pennsylvania Street 2. 131st Street near the proposed Access Point 1 Second, to estimate the number of new trips that will be generated by the proposed development. Third, to distribute the generated traffic volumes from the proposed development onto the public roadway system and intersec- tions that have been identified as the study area. Fourth, 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: a. Existing Conditions - Based on existing roadway condi- tions and traffic volumes. b. Proposed Development - Add the traffic volumes that would be generated by the proposed development to the existing traffic volumes. Finally, to prepare a TRAFFIC OPERATIONAL 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 along the east side of U.S. 31 and immediately north of 131st Street. This tract is 2 bounded by an existing church to the east and vacant land to the south. This proposed development will consist of 15,000 square foot lighting retail center and 13,200 square feet for a paint and hardware store. The proposed plan for this development includes one point of access along 131st Street. Figure 1 is an area map and conceptual master plan of the proposed site, including the location of the proposed access point. STUDY AREA The study area for this development includes 131st Street - from U.S. 31 to Pennsylvania Street. The study area will include the following intersections: 1. 131st Street and Pennsylvania Street 2. 131st Street and U.S. 31 3. U.S. 31 and 131st Street. 3 DESCRIPTION OF THE ABUTTING STREET SYSTEM This proposed development will be served by the public roadway system which includes 131st Street and Pennsylvania Street. 131st Street - is a minor east -west cross - county roadway. At the intersection with U.S. 31 a center median has been installed to prevent traffic from turning left onto U.S. 31 and from turning left to 131st Street. Pennsylvania Street - is a minor two -lane north south street. Pennsylvania Street serves several residential areas and a business area with north south access. This intersection is controlled by a stop sign with Pennsylvania Street stopping for 131st Street. U.S. 31 CORRIDOR STUDY Currently the Indiana Department of Transportation is studying the U.S. corridor through Carmel and north of Westfield, Indiana. The purpose of this study is to determine future demands and future geometrics need to accommodate the anticipated growth throughout the area. Several options are being reviewed by the Indiana Department of Transportation, some of these options include continuous frontage roads and directional interchanges at major 5 intersections. Public informational meetings have been held to explain these options. However, at this time there have been no decisions made on this corridor, future interchanges or future frontage routes. These alternatives are in the conceptual stage. No design contracts have been awarded and no plans have been approved for any of the alternatives. TRAFFIC DATA Peak hour manual turning movement traffic volume counts were made at the intersection of 131st Street and Pennsylvania Street. These traffic volume counts include an hourly total of all "through" traffic and all "turning" traffic at the intersections. These traffic volume counts were made during the hours of 7:00 AM to 9:00 AM and 4:00 PM to 6:00 PM in August, 1995. A twenty -four hour traffic count was made along 131st Street near the location of the proposed access point. This traffic count was conducted during the days that the intersection count was conducted. These traffic volume data have been published in the back of this report (see Appendix A). 6 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 paint and hardware center. 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. Data collected by A & F Engineer- ing Co., Inc. at similar lighting retail centers were used to calculate the trips that can be expected by the lighting center. Table 1 is a summary of the trips that will be generated by the proposed development.

Therefore, there will be no reduction taken for pass -by trips. PEAK HOURS Throughout this analysis, all reference to peak hours will be 7:00 AM to 8:00 AM and 4:00 PM to 5:00 PM. ASSIGNMENT AND DISTRIBUTION OF GENERATED TRIPS The study methodology used to determine the traffic volumes, from the proposed development, 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 various access points to the public street system. Based on the proposed site plan, one access point is planned for 131st Street. Therefore 100 percent of the traffic will be assigned to this access point. 2. To determine the volumes of traffic that will be added to the public roadway system, the generated traffic must be distrib- uted by direction to the public roadways and to the proposed 8 access points. For the proposed development the distribution was based on the existing traffic patterns and the assignment of generated traffic. The distribution of the generated traffic volumes for the proposed development is shown on Figure 2. 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 study area inter- sections. The Peak Hour generated traffic volumes are shown on Figure 3. These data are based on the previously discussed trip generation data, assignment of generated traffic, and distribution of generated traffic. TOTAL TRAFFIC VOLUMES 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 then be analyzed as to the adequacy of the existing roadway system. The following scenarios will be reviewed as a part of this analysis: 1. Existing Traffic Volumes- These are the traffic volumes that were obtained in August 1995. Figure 4 is a summary 9 of these traffic volumes at the study intersections for the peak hours. 2. Existing Traffic Volumes plus Site Generated Traffic Volumes- These volumes are the sum of the existing traffic volumes and site generated traffic volumes. Figure 5 is a summary of these traffic volumes at the study intersection for the peak hours. 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 includes traffic volumes, intersection geometry, number and use of lanes and, in the case of signalized intersections, traffic signal timing. To determine the level of service at each of the study intersections, a capacity analysis has been computed using the recognized computer program based on the Highway Capacity Manual (HCM)2. The Department of Community Development has requested that an 2' Transportation Research Board, National Research Council, Washington, D.C., Special Report 209, 1985. 13 analysis be made for the AM Peak Hour and PM Peak Hour for each of the scenarios that were identified in the section titled "Total Traffic Volumes" at each study intersection. These analyses have been completed and the computer solution showing the LOS results are included in Appendix A. The tables that are included in this report are a summary of the results of the LOS analyses and are identified as follows: Table 2 - 131st Street and Pennsylvania Street Table 3 - U.S. 31 and 131st Street Table 4 - 131st Street and Proposed Access Point 15 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 TABLE 2 LEVEL OF SERVICE SUMMARY 131ST STREET & PENNSYLVANIA STREET AM PEAR HOUR Movement Westbound Left Northbound Left Northbound Right PM PEAK HOUR Movement Westbound Left Northbound Left Northbound Right Scenario 1 - Existing Traffic Volumes Scenario 1 2 A A A A A A Scenario 1 2 A A A A A A Scenario 2 - Existing Traffic Volumes + Proposed Development Traffic Volumes 16 TABLE 3 LEVEL OF SERVICE SUMMARY U.S. 31 & 131ST STREET AM PEAK HOUR Movement Westbound Right PM PEAK HOUR Movement Westbound Right Scenario 1 2 A A Scenario 1 2 B B Scenario 1 - Existing Traffic Volumes Scenario 2 - Existing Traffic Volumes + Proposed Development Traffic Volumes 17 Scenario Scenario TABLE 4 LEVEL OF SERVICE SUMMARY 131ST STREET & PROPOSED ACCESS POINT AM PEAK HOUR Movement Scenario 1 2 Eastbound Left A Southbound Left A Southbound Right A PM PEAK HOUR Movement Scenario 1 2 Eastbound Left A Southbound Left A Southbound Right A 1 - Existing Traffic Volumes 2 - Existing Traffic Volumes Traffic Volumes 18 + Proposed Development CONCLUSIONS The conclusions that follow are based on the generated traffic volumes, capacity analysis, and the resulting Level of Service. 131st Street and U.S. 31 This intersection is currently operating at Level of Service "A" in the AM Peak Hour and Level of Service "B" in the PM Peak Hour with the existing roadway conditions. After the generated traffic volumes have been added to the street system, the capacity will remain at the same Level of Service. 131st Street and Pennsylvania Street This intersection is currently operating at Level of Service "A" in the AM Peak Hour and the PM Peak Hour with the existing roadway conditions. After the generated traffic volumes have been added to the street system, the capacity will remain at the same Level of Service above "A ". 131st Street and Proposed Access Point This intersection will operate at level of service A in the AM Peak Hour and the PM Peak Hour with the existing roadway 19 conditions and the generated traffic volumes added to this intersection. Based on peak hour generated traffic volumes a passing blister is not warranted at this location. RECOMMENDATIONS Basedon the analysis and the conclusions, the following recommen- dations are made to insure that the roadway system will operate at acceptable levels of service if the site is developed as proposed in this rezoning petition. 131st Street and Proposed Driveway 1. The main driveway to the proposed development should be constructed with two outbound lanes and one inbound lane. All lanes should be a minimum of 12 feet in width. A right turn lane should be installed at the main entrance to allow traffic entering the site from the east to do so without interfering with through traffic. SUMMARY The development of the Indiana Lighting project as proposed will not adversely affect the operation of the public roadway system on 131st Street, Pennsylvania Street or U.S. 31. 20 ■ An "on- site" review of the roadway system did not indicate that there would be any sight distance problems at the approach. 21 APPENDIX A This document contains the traffic data that were used in the Traffic Operational Analysis for the proposed Lighting Center and support retail to be located in the northeast quadrant of U.S. 31 and 131st Street. Included are the intersection turning movement traffic volumes counts, the intersection capacity analyses for each of the study intersections for the AM Peak Hour and the PM Peak Hour. 22 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 A & F ENGINEERING CO., INC. 24 HOUR TRAFFIC VOLUMES CLIENT : INDIANA LIGHTING CENTER, INC.
