Indiana Registration 890237 III • • CMC PROPERTIES TRAFFIC OPERATIONS ANALYSIS INTRODUCTION This TRAFFIC OPERATIONS ANALYSIS, prepared at the request of CMC Properties is for an office development that is to be located along 1314 Street west of U.S. 31 in Clay Township, Hamilton County, Indiana. 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 peak hour traffic volume counts at the following locations: • 1314 Street and U.S. 31 • 1314 Street and Meridian Corners Boulevard Second, to estimate the number of new trips that will be generated by the proposed office development. 1 • • CMC PROPERTIES TRAFFIC OPERATIONS ANALYSIS Third, to assign the generated traffic volumes to the driveways and/or roadways that will serve to provide access to the proposed development. Fourth, to distribute the generated traffic volumes from the site onto the public roadway system and intersections which have been identified as 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 Conditions-Based on existing traffic volumes. SCENARIO 2: Proposed Development—Add the new traffic volumes that will be generated by the proposed development to the existing traffic volumes. 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 residential development is to be located along 131x` Street west of U.S. 31 in Clay Township, Hamilton County, Indiana. As proposed, the development will consist of 100,000 square feet of general office. The primary access will be on Meridian Corners Boulevard. Figure 1 is an area map of the site. 2 • I CMC PROPERTIES TRAFFIC OPERATIONS ANALYSIS STUDY AREA The study area for this analysis will include the following intersections: • 130 Street and U.S. 31 • 131st Street and Meridian Corners Boulevard DESCRIPTION OF THE ABUTTING STREET SYSTEM This proposed development would be served by the public roadway system that includes 131x` Street and Meridian Corners Boulevard 130 Street—is an east/west roadway that runs through the City of Carmel as Main Street. This roadway serves several commercial and residential developments along the corridor. At the 131x` Street intersection with U.S. 31, 131st Street is stop sign controlled. U.S. 31 has been developed with a center median and therefore traffic cannot cross U.S. 31 in the east and west direction. Meridian Corners Boulevard—is a two-lane roadway that currently services a residential area and Day Care. South of 131x` Street, Meridian Corners Boulevard becomes 126th Street at U.S. 31. 4 • • CMC PROPERTIES TRAFFIC OPERATIONS ANALYSIS TRAFFIC DATA Peak hour manual turning movement traffic volume counts were made at the study intersections by A&F Engineering Co., LLC. The manual traffic volume counts were made during the hours of 6:00 a.m. to 9:00 a.m. and 3:00 p.m. to 6:00 p.m. in February 2001 and are included in Appendix A. 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 is a summary of the trips that will be generated by the proposed development. TABLE 1 - GENERATED TRIPS FOR PROPOSED DEVELOPMENT DEVELOPMENT INFORMATION GENERATED TRIPS ITE AM AM PM PM LAND USE CODE SIZE ENTER EXIT ENTER EXIT Office 710 100,000 s.f. 164 22 33 159 INTERNAL TRIPS An internal trip results when a trip is made between two land uses without using the roadway system. Typically, internal trips occur in mixed-use developments. This is a single use development. Therefore, no reductions will be applied for internal trips. PASS-BY TRIPS Pass-by trips are trips already on the roadway system that decide to enter a land use. A residential development is a destination land use. Therefore, no reduction will be applied for pass-by trips. ' Trip Generation, Institute of Transportation Engineers, Sixth Edition, 1997. 5 • I TRAFFIC OPERATIONS ANALYSIS CMC PROPERTIES n •°. PEAK HOUR Based on the manual traffic volume counts, the peak hours for the study intersections are 7:00 AM to 8:00 AM and from 5:00 PM to 6:00 PM. Therefore, the actual peak hour calculated will be used for this analysis to represent the worst case scenario. ASSIGNMENT AND DISTRIBUTIION 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 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. The assignment and distribution of the generated traffic volumes for the proposed development are shown on Figure 2. 6 • I CMC PROPERTIES TRAFFIC OPERATIONS ANALYSIS PROPOSED DEVELOPMENT GENERATED TRIPS ADDED TO THE STREET SYSTEM Generated traffic volumes that can be expected from the proposed development have been prepared for the proposed access points and for the study area intersections. 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. 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 signal timing. To determine the level of service at each of the study intersections, a capacity analysis has been made using the recognized computer program based on the Highway Capacity Manual(HCM)2. DESCRIPTION OF LEVELS OF SERVICE The following list shows the delays related to the levels of service for unsignalized intersections: Level of Service Control Delay (seconds/vehicle) A Less than or equal to 10 B Between 10.1 and 15 C Between 15.1 and 25 D Between 25.1 and 35 E Between 35.1 and 50 F greater than 50 2 Transportation Research Board, National Research Council, Washington, DC, Update of Special Report 209, 1997. 8 • I CMC PROPERTIES TRAFFIC OPERATIONS ANALYSIS 'ara:b'Tf- i i :b, C`` e,;.: di_ x +. k -. Z .° 'Sb.4=N `. ,._` - aqt _. f•Y ,.. .' _ , 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. The Carmel Department of Community Services has requested that an analysis be 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 Conditions - These are the traffic volumes that were obtained in February 2001. Figure 4 is a summary of these traffic volumes at the study intersections. SCENARIO 2: Proposed Development - Figure 5 is a summary of these traffic volumes at the study intersections for the peak hour. The requested analyses have been completed and the computer solutions showing the level of service results are included in Appendix A. The tables that are included in this report are a summary of the results of the level of service analyses and are identified as follows: Table 2— 131 ` Street and U.S. 31 Table 3— 131 ` Street and Meridian Corners Boulevard 10 • CMC PROPERTIES TRAFFIC OPERATIONS ANALYSIS -•, .,n ...._y , ; _ .. ��.,�,�,.

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. 131 fr STREET AND U.S. 31 Existing (Scenario 1) - A review of the level of service for each of the intersection approaches, with the existing traffic volumes and existing geometrics, has shown this intersection is operating at acceptable levels. Proposed Development (Scenario 2) - When the traffic volumes from the proposed development are added to the existing traffic volumes to this intersection will continue to operate at the acceptable levels of service during the AM and PM Peak Hour. 3. 131 sr STREET AND MERIDIAN CORNERS BOULEVARD Existing (Scenario 1) - A review of the level of service for each of the intersection approaches, with the existing traffic volumes and existing geometrics, has shown the intersection is working at acceptable levels of service during both the AM and PM Peak Hour. Proposed Development (Scenario 2) - When the traffic volumes from the proposed development are added to the existing traffic volumes, the intersection will continue to operate at an acceptable level of service. 14 • • CMC PROPERTIES TRAFFIC OPERATIONS ANALYSIS RECOMMENDATIONS Based on this analysis and the conclusions, the following recommendations are made to insure that the roadway system will operate at acceptable levels of service if the site is developed as proposed. 131n STREET AND U.S. 31 • No changes are necessary at this intersection. 131n STREET AND MERIDIAN CORNERS BOULEVARD • No changes are necessary at this intersection. ACCESS POINT • Provide 24-feet of pavement for outbound traffic. This will provide for a future right-turn lane and left-turn lane when required. • Provide a northbound right-turn lane on Meridian Corners Boulevard. 15
