<br />1 <br /> <br />I <br /> <br /> <br />1 <br /> <br />GOSNEY & SONS, INC. ENTRANCE ANALYSIS <br />The entrance to the gravel pit batch plant site is at the intersection of CR 521 <br />and the site driveway. There are no serious problems indicated with this <br />access to the site relative to capacity and level-of-service at the present time. <br />There is, however, some concern relative to the safe operation of the main <br />entrance to the site at CR 521. Observations indicate that the through traffic <br />on CR 521 travels at relatively high speeds iii the vicinity of the site. This <br />situation is present because of a variety of factors one of which is that the <br />posted speed limit is 55 mph. The State Highway Access Code indicates that <br />a right turn deceleration speed change lane and a right turn acceleration speed <br />1 <br />1 <br /> <br /> <br /> <br /> <br /> <br /> <br />J <br />change land would be required if this were a State Highway. In view of the <br />heavy trucking operation involved, and the current relatively high accident <br />rate on this road (0.72 accidents per mile per year), a right turn deceleration <br />speed change lane and a right turn acceleration speed change land should be <br />considered. Figure 5 shows a possible geometric configuration for the driveway <br />intersection at CR 521. This figure indicates the geometry for both 45 mph <br />and 55 mph speed limits on CR 521. It may be desirable to reduce the posted <br />speed limit from 55 mph to 45 mph in the vicinity of the site. This would <br />improve the safety of CR 521 as well as improve the egress left turning <br />movement performance. <br />19 <br /> <br />
