31 <br />Trip Generation <br />The trip generation potential of the proposed h-brary during a typical weekday was estimated using the ITE Trip <br />Generation Manual, $~' Edition,. and is shown in Table 1. <br />Table 1 <br />Site Trip Generation Table <br />It. is estimated that the .proposed library will generate approximately 1,232 total trips (616 entering and 616 <br />exiting) during a_typica124-hour weekday period_ Of these daily traffic. volumes, it is anticipated that 21 trips <br />(15 entering and 6 exiting) will occur during t'de AM peak hour, and 1:41 _trips (68 entering and 73 exiting} wi71 <br />occur during the PM peak hour. <br />Note that this. represents a conservative estimate of the number of velzicle trips that will access the site. 'The <br />surrounding area. is primarily residential, the site is adjacent to Carrbom Elementary School, there. are striped <br />bike Lanes on Hillsborough Road, and an .existing sidewalk. Therefore, it is reasonable to assume that. a <br />significant portion of Iibrary visitors will either walk or ride a bike to the library, which will help minimize th.e <br />number of vehicle trips impacting the roadway network. <br />Assessment of the Need for Off-Site Roadway Improvements <br />The Florida Department of Transportation (FDOT) publishes roadway capacity thresholds for various types of <br />roadways, which are widely accepted within the .traffic engineering community. According to FDOT; a_ two- <br />lane roadway.such .as Hillsborough Road has a capacity of approximately 11,040 to 13,000 vehicles per day. At <br />build-out of the proposed library, the ADT volume on Hillsborough Road is expected be approximately 3,700 <br />vehicles per day in the vicinity of Main Street. Therefore, the projected traffic volume on Hillsborough Road <br />wi11 be only 30%~ of the.madway capacity. <br />Assuming the proposed site drivewayis designed correctly with adequate sight distance triangles, the horizontal <br />and vertical alignment of Hillsborough Road should allow for adequate sight distance for drivers entering and <br />exiting the site driveway. <br />Some drivers may experience long delays making left-turn movements in the uicinity of this site during, the AM <br />and PM peak hours; however; none of the nearby intersections are expected t© meet any traffic signal warrants <br />as described in the IManual on Uniform Traffic Control Devices (MtTTCD). <br />RANIEY KEiV(P <br />`-ASSOCIATES <br />
