Technology Enhanced Traffic Control Policy <br /> Purpose <br /> The City of Elk River seeks to optimize its existing traffic control measures in locations <br /> where unique situations exist. With evolving Technology Enhanced Traffic Control devices, <br /> it is crucial to analyze the effectiveness of each device and determine whether their use <br /> factually increases the safety and well-being of the public. <br /> This policy defines how devices are evaluated and recommended for application. Devices <br /> failing to meet the guidelines established by this policy will not be considered for installation <br /> unless they are a replacement to a previously installed, older technology system (standard <br /> flashing beacons, etc.). <br /> Policy <br /> Devices considered for use include: flashing LED regulatory (stop andyield) and warning <br /> (curve ahead, etc.) signs, digital speed feedback signs, and rectangular rapid-flashing beacons <br /> at pedestrian crosswalks. New devices, as developed,will be considered for addition to the <br /> Policy. <br /> The city will follow guidance for appropriate use as provided by the Minnesota Manual on <br /> Uniform Traffic Control Devices (MN MUTCD). <br /> Flashing LED Signs (Regulatory and Warning) <br /> Light Emitting Diode (LED) units may be used individually within the legend of a sign <br /> and/or the border of a sign to improve the conspicuity or to increase the legibility of sign <br /> legends and borders. <br /> Prior to implementing a flashing LED sign, the following conspicuity improvement <br /> alternatives shall first be considered: <br /> ■ Install an advanced warning sign on approach to the intersection or warning <br /> condition. <br /> ■ Increase the size of the existing signage. <br /> ■ Install a second sign of equal or lesser size on the left-hand side of the road (if <br /> allowed by MN MUTCD). <br /> ■ Add one or more red or orange flags (cloth or retroreflective sheeting) above a <br /> standard sign,with flags oriented at 45 degrees to the vertical. <br /> ■ Add a strip of retroreflective material to the sign support. <br /> Flashing regulatory and warning signs shall only be considered for installation in situations <br /> necessitating enhanced visibility of the sign not accomplished by the above treatment <br /> techniques. The city will follow the MnDOT Traffic Engineering Manual to create premises <br /> for use. For local road situations the manual provides instruction that use of these devices <br /> should be limited to locations where both of the following conditions exist: <br /> 0 <br />
