RESOLUTION NO. R-1314-117: A RESOLUTION OF THE COUNCIL OF THE CITY OF NORMAN, OKLAHOMA, APPROPRIATING $15,229 FROM THE CAPITAL FUND BALANCE TO PURCHASE TRAFFIC SIGNAL PARTS TO UPGRADE TRAFFIC SIGNALS AT THE INTERSECTIONS OF IMHOFF ROAD AND JENKINS AVENUE AND IMHOFF ROAD AND CHAUTAUQUA AVENUE TO BE REIMBURSED BY THE UNIVERSITY OF OKLAHOMA.
Body
BACKGROUND: The University of Oklahoma has plans to reconstruct a portion of Imhoff Road between Jenkins Avenue and Chautauqua Avenue. This portion of Imhoff Road was originally constructed by the University and remains under University ownership and maintenance. In January, 2014, Staff was first briefed about the project by Garver Engineers, the University's consultant on this roadway improvement project. The construction sequencing to be utilized on this project will have one half of the existing roadway closed at a time. During one phase, all traffic (one lane in each direction) will be carried on the existing two westbound lanes, and the other phase will have all traffic (again, one lane in each direction) carried on the existing two eastbound lanes. Each end of this segment of Imhoff Road is controlled by existing traffic signals. The existing vehicle detection systems utilized at both of these intersections involves loops cut into the pavement. The University is scheduled to begin work on this project in April, 2014.
The existing vehicle detection loops will become largely ineffective during various phases of the traffic control sequencing. The result could be that multiple movements will be forced into operation under maximum timing intervals because there will be no vehicle detection available through the existing loop detectors. For example, during the phase when westbound traffic is carried on the existing eastbound lanes, the existing loop detectors, even if construction does not destroy them, would be unusable on the other side of the median. To combat this issue, staff approached the...
