2.0 Existing Conditions Geometrics and Traffic Control Existing geometrics and traffic control at the subject intersections are as follows: CSAH 14 /CSAH 23 This intersection is presently controlled by stop signs on all approaches. Control at this intersection is supplemented by an overhead intersection control beacon providing a flashing, circular red signal indication for each approach. The north approach provides one through -left turn lane and one right turn lane. The south approach provides one through -left turn lane and one right turn lane. The east approach provides one through -left turn lane and one channelized right turn lane under yield condition. The west approach provides one through -left tum lane and one channelized right turn lane under yield condition. The speed limit for the north and south approaches is 50 mph. The speed limit for the east and west approaches is 40 mph. Intersection lighting is provided in the northwest and southeast corners. CSAH 14/4`h Avenue North This intersection is currently controlled by stop signs on the north and south approaches. The north approach provides one left - through -right turn lane. The south approach provides one left - through -right tum lane. The east and west approaches provide one through -left turn lane and one right turn lane. The speed limit for the north approach is 45 mph. The speed limit for the east, west, and south approaches is 50 mph. CSAH 23 /Pine Street This "T" intersection is currently controlled by a stop sign on the west approach. The north approach provides one through lane and one right turn lane. The south approach provides one through -left turn lane. The west approach provides one left- turn/right- turn lane. The speed limit for the north and south approaches is 55 mph. The speed limit for the west approach is 30 mph. Pine Street is aggregate surfaced. Existing Traffic Volumes To better understand the existing traffic conditions at the subject intersections, turning movement counts were completed during the AM and PM peak periods on April 26th and 27th and May 2nd and 3rd, 2006. The existing peak hour volumes are presented in the Traffic Forecasts section. The collected turn movement data indicated the AM peak hour occurs from 7:00 to 8:00 AM and the PM peak hour from 4:30 to 5:30 PM.
