This is the development as proposed by C P Morgan Co Inc and J C Hart Co Inc Third, to assign the generated traffic volumes to the driveways and/or roadways that will provide access to each of the individual parcels that have previously been identified to be included in this analysis Fourth, to distribute the generated traffic volumes from each parcel 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 the intersections included in the study area for each of the following scenarios SCENARIO 1 Existing Conditions - Based on existing roadway conditions and existing traffic volumes SCENARIO 2 Comprehensive Plan - Add the traffic volumes that would be generated by the land use based on the comprehensive plan for the site of the proposed development to the existing traffic volumes SCENARIO 3 Proposed Development - Add the traffic volumes that will be generated by the proposed development to the existing traffic volumes SCENARIO 4 Vacant Land- Add the traffic volumes that will be generated from outside the study area through the year 2010 and by the surrounding vacant lands to the existing traffic volumes SCENARIO 5 Proposed Development (Year 2010) - Add the traffic volumes that will be generated by the proposed development to those volumes used in scenario 4 C P MORGAN CO INC.AND J C.HART CO INC.-GRAY ROAD TRAFFIC IMPACT ANALYSIS Finally, to prepare a TRAFFIC IMPACT 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 is to be located along Gray Road between 96th Street and 106th Street in Carmel, Indiana As proposed, the development will consist of 266 dwelling units of apaiLment homes and 135,000 square feet of office park Figure 1 is an area map of the proposed development including the proposed access point DESCRIPTION OF COMPREHENSIVE PLAN USE The City of Carmel Department of Community Services comprehensive plan shows this site can be developed with 516 multi-family dwelling units 3 i i. C.P. MORGAN CO INC. AND J C. HART Co INC.- GRAY ROAD TRAFFIC IMPACT ANALYSIS DESCRIPTION OF THE ABUTTING STREET SYSTEM This proposed development would be served by the public roadway system that includes 96th Street and Gray Road 96Th STREET - is an east -west, five -lane major roadway that serves the northern suburbs of Indianapolis GRAY ROAD - is a north - south, two -lane collector that serves Hamilton County Gray Road terminates at its intersection with 96th Street 96`" Street & Gray Road - This intersection is controlled by a full actuated traffic signal The eastbound and westbound approaches consist of an exclusive left -turn lane, an exclusive right - turn lane, and two through lanes The southbound approach consists of an exclusive left -turn lane, an exclusive right -turn lane, and a single through lane The northbound approach is a development dnveway that includes an exclusive left -turn lane, an exclusive right -turn lane, and a single through lane 106`" Street & Gray Road - This intersection is four -way stop controlled with all approaches consisting of one shared lane TRAFFIC DATA Peak hour manual turning movement traffic volume counts were made at 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 4 00 PM to 7 00 PM in August 2000 These counts 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 tnps that will be generated by the proposed development This report is a compilation of tnp data for vanous land uses as collected by transportation professionals throughout the United States in order to establish the average number of taps generated by vanous land uses Table 2 is a summary of the tnps that will be generated by the proposed development i Tnp Generation, Institute of Transportation Engineers, Sixth Edition, 1997 7 C P MORGAN Co INC AND J C HART Co INC - GRAY ROAD TRAFFIC IMPACT ANALYSIS TABLE 2 - GENERATED TRIPS FOR PROPOSED DEVELOPMENT DEVELOPMENT INFORMATION GENERATED TRIPS LAND USE ITE CODE SIZE AM ENTER - AM EXIT PM ENTER PM EXIT Multi- Family 220 266 DU 22 114 109 54 Office Park 750 135,000 SF 251 31 38 232 GENERATED TRAFFIC VOLUMES FOR COMPREHENSIVE PLAN Trip Generation report was used to calculate the number of tnps that will be generated by the site based on the comprehensive plan Table 3 is a summary of these traps TABLE 3 - GENERATED TRIPS FOR COMPREHENSIVE PLAN DEVELOPMENT INFORMATION GENERATED TRIPS PARCEL I 1E ITE CODE AM AM PM PM LAND USE CODE SIZE ENTER EXIT ENTER EXIT Multi - Family 220 516 DU 42 218 200 98 GENERATED TRAFFIC VOLUMES FOR VACANT LANDS Trip Generation report was used to calculate the number of tnps that will be generated by the vacant lands Table 4 is a summary of the tnps that will be generated by the vacant parcels TABLE 4 - GENERATED TRIPS FOR VACANT PARCELS DEVELOPMENT INFORMATION GENERATED TRIPS PARCEL LAND USE ITE CODE SIZE AM ENTER AM EXIT PM ENTER PM EXIT A Sin • le- Family 210 40 DU 9 28 30 17 B General Office 710 60,000 SF 109 15 25 122 C New Car Sales 841 120,000 SF 194 72 134 202 D Retail 820 258,746 SF 172 110 564 612 Retail New Tries = 70 5% otals .Vacant :Land.New.Tnps $ :- 121 433 78 :.: 193 >- 398 587, 431 :. . INTERNAL TRIPS An internal trip results when a trip is made between two land uses without using the roadway system Typically, internal traps occur in mixed -use developments However, the internal trap 8 C.P MORGAN CO INC AND J C HART CO INC - GRAY ROAD TRAFFIC IMPACT ANALYSIS percentages between residential and office uses published in the Trip Generation Handbook are very low Therefore, these reductions were not considered in this report PASS -BY TRIPS Pass -by tnps are trips already on the roadway system that decide to enter a land use The vacant retail land will generate pass -by trips Therefore, the appropnate trip reductions will be taken This pass -by reduction is applied to the trips listed in Table 3 The remaining land uses will not produce pass -by tnps Therefore, no reductions will be taken for these land uses ANNUAL GROWTH RATE FOR BACKGROUND TRAFFIC The Department of Community Services has prepared the estimate of the annual growth rate for background traffic that will be generated on the street system included in the study area The annual growth rate of background traffic to be used for this analysis is one percent for all streets ASSIGNMENT AND DISTRIBUTION OF GENERATED TRIPS The study methodology used to determine the traffic volumes from the vacant lands and 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 vanous 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 dnveways 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 dnveway For the proposed development, the distribution was based on the existing traffic patterns and the assignment of generated traffic The assignment and distnbution of the generated traffic volumes for the proposed development and Comprehensive Plan are illustrated on Figures 3, 4 and 5 Furthermore, the assignment and distribution of the generated traffic volumes for the vacant lands are illustrated on figures in the Appendix 2 Trip Generation Handbook, Institute of Transportation Engineers, October, 1998 9 C.P. MORGAN Co INC. AND J.C. HART Co INC.- GRAY ROAD TRAFFIC IMPACT 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 point and for each of the study area intersections The Peak Hour generated traffic volumes are shown on Figure 6 These data are based on the previously discussed tnp generation data, assignment of generated traffic, and distribution of generated traffic COMPREHENSIVE PLAN GENERATED TRIPS ADDED TO THE STREET SYSTEM Generated traffic volumes that can be expected from the Comprehensive Plan land use have been prepared for the proposed access point and for each of the study area intersections The Peak Hour generated traffic volumes are shown on Figure 7 These data are based on the previously discussed trip generation data, assignment of generated traffic, and distnbution of generated traffic VACANT LAND TRAFFIC VOLUMES ADDED TO THE STREET SYSTEM Generated traffic volumes that can be expected from the vacant land developments, within the study area, have been prepared for the study area intersections The Peak Hour generated traffic volumes for the vacant lands are shown on figures located in the Appendix These data are based on the previously discussed tnp generation data, assignment of generated traffic, the distnbution of generated traffic and the previously mentioned Traffic Impact Analysis conducted by A & F Engineering Co , LLC YEAR 2010 TRAFFIC VOLUMES To evaluate the future impact of this development on the public roadway system, the existing traffic volumes must be projected forward to a design year The design year used for this project will be year 2010 For this analysis, an annual growth rate of one percent is used for all streets The Year 2010 projected traffic volumes are shown on Figure 8 13 C P MORGAN CO INC AND J C HART CO INC - GRAY ROAD TRAFFIC IMPACT 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 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)3 DESCRIPTION OF LEVELS OF SERVICE The following descriptions are for signalized intersections Level of Service A - descnbes 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 - descnbes 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 3 Transportation Research Board, National Research Council, Washington, DC, Update of Special Report 209, 1997 17 L C P MORGAN CO INC AND J C HART CO INC - GRAY ROAD TRAFFIC IMPACT ANALYSIS Level of Service D - 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 Level of Service E - 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, 1 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 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 18 C P MORGAN Co INC AND J C HART Co INC - GRAY ROAD TRAFFIC IMPACT 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 aggregated 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, if required, 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 August 2000 Figure 9 is a summary of these traffic volumes at the study intersections for the peak hours SCENARIO 2 Existing Traffic Volumes -r Comprehensive Plan Land Use Traffic L olinies -
