II - BACKGROUND DATA Roadwav Characteristics CSAH 14 (Main Street) is an cast/west "A" Minor Arterial (connector /expander) traveling through the City of Centerville. Primarily, this roadway, through the City of Centerville, is a two lane facility (one lane in each direction) with paved shoulders. Adjacent to the elementary school, a sidewalk exists on the north side of the roadway. A 30mph speed limit is posted through the area adjacent to the elementary school. Approaching the intersection of Progress Road, from the east (westbound), a slight upgrade exists. A striped pedestrian crosswalk is provided across CSAH 14 (Main Street) on the east side of Progress Road. Currently, pedestrian crossing signs exist approaching the intersection from both direction. A figure illustrating the existing roadway configuration, signing and striping is included as Figure 2 in the Appendix. Currently, the CSAH 14 corridor has substantial "Visual Interference ". The narrow right -of -way together with several buildings /obstructions immediately adjacent to the right -of -way, contribute to this interference. A slight upgrade exists on CSAH 14 approaching the school from the west. The Anoka County Highway Department conducted a review of the existing traffic control devices on CSAH 14 (Main Street). Several recommendations for improvements were identified on or adjacent to the roadway, including, sign locations and obstructions to sight lines. A copy of the County study is included in the Appendix. Existing_ Traffic Volumes Traffic volume data was obtained from the Anoka County Traffic Volume Map for 1996 traffic conditions. The average daily traffic (ADT) in 1996 on CSAH 14 (Main Street), in the area of the elementary school, was 7,759 vehicles. Based on an hourly traffic count at the intersection of CSAH 14 and CR 54, the peak hours on Main Street are 5:00 -6:00 PM and 7:00 -8:00 AM with the peak school times of 3:00 -4:00 PM and 8:00 -9:00 AM. Existing Pedestrian Volumes The Anoka County Highway Department conducted a pedestrian/gap -time study at the existing school crossing on CSAH 14 at Progress Road, on December 17, 1997. The study found there was an adequate number of gaps on CSAH 14 for pedestrians crossing this roadway. Based on the School Crossing Study, no additional controls were warranted at the crossings. A copy of the County's study is included in the Appendix. School Crossing Study Anoka County WSB Project No. 1044.08 Page 2
