I <br />1 <br />1 <br />i <br />Generally speaking, the next -best type of control after a traffic signal is an officer or other <br />trained person manually�directing traffic at a busy intersection. As in the example above, <br />there are several large and/or complex intersections in the city where trained staff <br />(including specially- trained for this type of event) could direct. traffic. It would be <br />desirable to have these traffic controllers not be police or other emergency service <br />responders, since they are likely to have numerous and multiplying demands on their time <br />due to other needs. <br />b. Temporary power supply for traffic signals <br />Temporary power from generators could be supplied to some subset of the city's traffic <br />signals. This locallyi generated power could be used to operate a signal at close to normal <br />operation (including traffic actuation, pedestrian signals, etc.) or in a reduced operation <br />mode such as fixed -time or flashing red. <br />1 <br />1 <br />c. Stop sign control <br />A large number of intersections that normally operate with a traffic signal, could in a power <br />outage operate adequately with temporary stop sign controls. The temporary signs would <br />need to be secured in some fashion at each location. <br />d. Criteria for prioritization <br />In order to provide temporary traffic control in an orderly fashion and in a way that <br />addresses the most critical locations first, some type of priority- setting criteria are needed. <br />Generally the heaviest traffic volume locations will also be those with the largest <br />intersections and, in most cases, those with full traffic actuation and turn movement <br />indicators. Intersections with these characteristics will probably be the first priority for <br />installing temporary traffic control. At the opposite end of the scale, several traffic signals <br />at outlying locations with lighter traffic volumes will likely be the lowest priority <br />intersections for temporary control. In between there are many locations with moderate -to- <br />heavy volumes that should be assigned a second or third priority. <br />This plan uses Functional Classification as the basic framework for designating priorities. <br />Streets in Eugene are classified as either: <br />Major arterials (examples: Highway 99, Coburg Road, Franklin Boulevard) <br />Minor arterials (examples: Pearl and Oak Streets, Cal Young Road, South Willamette) <br />Major or minor collectors (examples: Willakenzie Road, Taney Street, First Ave.), or <br />Local streets (most residential streets and a few commercial or industrial streets) <br />These classifications are closely related to traffic volumes, typical trip length, and connectivity to <br />major destinations or higher - classified streets. Therefore using the classification of a given street <br />provides a close approximation of its rank or importance, relative to other streets in the overall <br />system. <br />The basic proposal for prioritizing traffic control is to put the highest form of control, and deploy <br />Page 23 of 36 <br />Last Revised all 0/08 <br />
