Hempen, Jr., P.E., Director of Public Works/County Engineer WI ' From: Wayne Howard, P.E., Sr. Engineer 14'..ta COLORADO RE: WCR 24 and WCR 19 Intersection I have received two service call requests, one from Wendy King and one from Bob Nehrig both concerning the intersection of WCR 24 and WCR 19 as well as a short stretch of WCR 24, approximately 1000' east of WCR 19. They are requesting a four-way stop be installed at the intersection as well as a reduced speed limit on the stretch of WCR 24 in front of the homes and businesses. I have been in contact with both parties and have performed a site visit to investigate their concerns. I have also received information from traffic classifier counters that I had placed at all legs of the intersection. Shown in Figure 1, are the results from the traffic counts. My findings are described below: Four-Way Stop The Manual on Uniform Traffic Control Devices (MUTCD) gives guidance on the applications of Multiway Stop Signs. Criteria such as accident history, traffic volumes, and speed are used to determine when multiway stop application should be used. This intersection currently does not meet any of the listed criteria. In the past this intersection has be a hot spot for accidents averaging three accidents per year. Public Works install oversized 48" stop signs and stop ahead signs in 2004 to help emphasis the forthcoming stopped condition. Since the installation of the 48" stop signs, the accidents have been reduced to one per year, although the accident in 2006 involved 12 people and three vehicles. Speed Limit on WCR 24 WCR 19 1 The posted speed limit in all AADT=1687/ directions is 55 mph. The 85%=61mph request was to reduce the AADT= 1632 p speed osted limit east of the 85%=53 MPH intersection in a section that—\ WCR 24 has several homes and Ai businesses adjacent to the roadway. The MUTCD gives guidance on establishing speed N / limits. When establishing a AADT= 1485 i AADT=1010 speed limit, it should be within 85%=62 mph 85%=57 MPH 5 mph of the 85% speed. In this area, the 85% speed limit Figure I was 57 mph. Based upon this criterion, 55 mph is a justifiable speed limit. The MUTCD also lists other Optional criteria that can be used to post speed limits. Factors such as road characteristics, shoulder condition, roadside development, etc., should be considered. As shown on the attached map, the area does have roadside development that should be considered. In my opinion, the speed limit for the section of WCR 24 shown on the map is less than 55 mph, based upon the high number of access points and roadside environment which includes trees and bushes. I recommend establishing a speed reduction zone on WCR 24 as it approaches WCR 19 from both directions. The speed limit of 55 mph on WCR 24 would be gradually reduced to 30 mph as it approaches the intersection as shown on the attached map. Speed limits would transition from 55 mph to 45 mph to 30 mph spaced at 1000' minimum transition lengths. I recommend extending this transition length to 2000' on WCR 24, east of WCR 19, based upon the roadside characteristics as discussed previously.
