RESOLUTION NO. R-1415-33: A RESOLUTION OF THE COUNCIL OF THE CITY OF NORMAN, OKLAHOMA, APPROPRIATING $60,500 FROM THE CAPITAL FUND BALANCE TO BE USED TO FULLY FUND AND IMPLEMENT AN ADAPTIVE SIGNAL SYSTEM ON STATE HIGHWAY 9 BETWEEN 24TH AVENUE S.W. AND JENKINS AVENUE.
Body
BACKGROUND: The Traffic Control Division manages traffic signal timing in a variety of ways. The simplest is an isolated traffic signal, such as the one located at the intersection of 12th Avenue NE and Franklin Road. Traffic signals such as this one operate in response to the traffic demand independent of the operation of other nearby traffic signals. In situations where the City has a series of traffic signals along a busy arterial roadway and in close proximity to each other, it becomes desirable to coordinate the operation of the signals. This is done by physically interconnecting each signal with fiber optic cable or copper wire cable to assure that the beginning and end of the green interval from one signal to the next is programmed in a way that facilitates the flow of traffic along the more heavily travelled roadway. An example of this is the ten signalized intersections on Robinson Street, between 36th Avenue NW and Porter Avenue.
Over the years, City staff has work diligently to modernize the traffic control equipment used at intersections along coordinated corridors. This effort has allowed the City to begin considering the use of higher-level systems such as "adaptive control". This modernization effort has included using fiber optic cable to interconnect intersections, using video to detect vehicular traffic rather than in-pavement loop detection, and using the most modern traffic signal controllers.
A project was requested as part of the FYE 2015 Budget to implement a higher-level, traffic signal adaptive control system for State Highway 9, between 24th Avenue SW and Jenkins Avenue. This corridor was chosen because of heavy use during special events at th...
