TRAFFIC ANALYSIS REPORT JANUARY 15~ 1993 PROPST PROPERTY DEVELOPMENT PLAN SARAH W. LABELLE TRANSPORTATION PLANNER The planned development for the Propst property includes parcels of different land uses which will significantly impact traffic flows on the surrounding road systems. Although this analysis is based on a maximum build-out condition which would extend over a long period of time, it is necessary to consider possible current and future needs for existh]g road improvement, expansions and new road links. Trip generations for each of the four parcels in the development were calculated using the Institute of Transportation En~neers (ITE) Trip Generation manual, 4th Edition. The different land use categories include R-15 (single family residenffal), C-1 (neighborhood commercial) and I-1 (light industrial) each wi~h a list of restricted land uses. It is not known at this time what types of industry will be created in ~he parcels, as the variety of listed uses has a great range of traffic impacts. W ha t follows ~s a brief description and week-day trip generation of each land use category. The development plan calls for 312 single family residential lots in parcel A, the north section of the property. Each housin~ unit is averaged at 10 trips/day yielding approximately 3120 for the subdivision. The commercial land use is located immediately south of the residential area. Trip ~eneration is based on a built upon area of 35% of the 42.21 total acres. Allowing for parking and walk area, six structures at 1000 square feet are calculated to generate approximately 6168 trips/day. The industrial parcels are located in the southern half of the development. It ~s presumed that there will exist two businesses in the eastern parcel and three in the southern parcel for a total of five. Each has an average of 469 employees with an average of 3.016 trips/day for a total of 7073 trips. The total trips generated by the Propst development plan has a potential of totaling to 16,361 trips/day. These ~rips will be distributed a]ong Concord Farms Rd. which is the "spine" of the development, Weddington Rd., US29, a major access to the site and in the future will include the proposed Westside Bypass. Figures 1 and 2 show the trip distributions by total numbers as well an by percent. A summary of the traffic impact, including recommendations, by each road is as follows: US29 The design capacity of this road is 50,000 trips/day with a current average daily traffic (ADT) of 15:500. The percent capacity at ~his rate is 31%. The ADT is projected ~o be at 42,900 or 86% capacity by the design year 2020. The Propst property's impact was included under the existing zoning and influenced this number. Based on the traffic generations projected for this proposed development, 60% of the traffic will use US29 to access the property with 40% using Weddin~ton Rd. At 60% projection, the additional trips using US29 will be 9,817. With this addition of trips the capacity at design year 2020 will be increased to 105%. It is clear ~hat road improvement (primarily intersection enhancement) is indicated in the near future. The recommendation is to construct right and left turn lanes into the site off US29 onto Concord Farms Rd.
