A&F ENGINEERING CO., INC. William J. Fehribach, P.E. President Indiana Registration 12855 ,y 1(64 Kelly A. Scott, EI Transportation Engineer iii BROWING INVESTMENTS.LNC.- MAYFLOWER SITE TRAFFIC SIGNAL WARRANT ANALYSIS INTRODUCTION This Traffic Signal Warrant Analysis, prepared at the request of Mr. F. Richard Rembusch representing Browning Investments, Inc., is for a traffic signal warrant analysis at the south driveway of a proposed business park along Michigan Road(US 421) in Hamilton County, Indiana. PURPOSE The purpose of this analysis is to determine if the existing traffic volumes plus generated traffic volumes from the proposed development will be sufficient to warrant the installation of a traffic signal at the south driveway of the development along Michigan Road(US 421). SCOPE OF WORK The scope of work for this analysis is the following: • Determine the existing traffic volumes along Michigan Road(US 421). • Estimate the volume of traffic that will be generated by the proposed business park. • Distribute the generated traffic to the proposed driveways. • Using the data that has been developed, prepare a traffic signal warrant analysis for the intersection of Michigan Road(US 421) and the Mayflower Road. DESCRIPTION OF THE PROJECT The proposed business park will be located along the west side of Mchigan Road (US 421) south of 106th Street in Hamilton, Indiana. The description of a business park according to the Trip Generation Report' is "a group of flex-type or incubator one or two story buildings served by a common roadway system. The tenant space is flexible to house a variety of uses; the rear side of the building is usually served by a garage door. Tenants may be start-up companies or small mature companies that require a variety of space." A business park may include office, warehouses, light industrial, retail, restaurants and other related land uses.

TABLE 1 - BUILD-OUT PLAN FIRST PHASE LAND USE SIZE Business Park 554,638 SF FULL BUILD-OUT LAND USE SIZE Business Park 1,124,001 SF TRAFFIC DATA A& F Engineering Co., Inc. has performed a 24-hour machine count along Michigan Road (US 421) in front of the proposed site. This traffic volume count includes an hourly total of all northbound and southbound traffic and was made in April 1997. The traffic volume count is included in Appendix A. TRIP GENERATION To determine the volume of traffic to be used in this traffic signal warrant analysis, the traffic generated by the proposed business park must be calculated. The estimate of traffic that will be generated by the proposed business park is a function of the size and character of the land use. Trip Generation report was used to calculate the number of trips that will be generated at this site. Trip Generation 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 2 is a summary of the generated trips on a weekday for the proposed business park. 2 I■ 1 ma 4=. .1 .. .

According to the traffic count collected along Michigan Road (US 421), there is a 50/50 split of traffic traveling northbound and southbound during a weekday. Therefore, for the proposed development, 50 percent of the generated trips were assigned to the north and 50 percent were assigned to the south. To determine the split between the north driveway and Mayflower Road, it was assumed that 100 percent of the trips from parcel 6 and 50 percent of the trips from parcel 5 and parcel 9 would exit the north driveway. These trips comprise approximately 16 percent of the generated trips resulting in a 84/16 split between the north driveway and Mayflower Road. The assignment and distribution of the generated traffic volumes are shown on Figure 2. The entering generated traffic volumes are not included in this analysis since the existing traffic volumes on the major street, Michigan Road (US 421), more than sufficiently meet the volumes required by the warrants. Table 3 shows the weekday generated traffic volumes exiting at Mayflower Road.
