Technology Enhanced Traffic Control Policy <br />Purpose <br />The CinT of Elk River seeks to optimize its existing traffic control measures in locations <br />�uhere unique situations e�st. With evolving Technology Enhanced Traffic Control devices, <br />it is cYucial to analyze the effectiveness of each device and determine whether their use <br />factuallyT increases the safetyT and well-being of the public. <br />This policyT defines how devices are evaluated and recommended for application. Devices <br />failing to meet the guidelines established by this policy will not be considered foY installation <br />unless theyT are a replacement to a previouslyT installed, older technology system (standard <br />flashing beacons, etc.). <br />Po�icy <br />Devices considered for use include: flashing LED regulator�T (stop and yTield) and warning <br />(curve ahead, etc.) signs, digital speed feedback signs, and rectangular rapid-flashing beacons <br />at pedestrian crosswalks. Ne`v devices, as developed, `vill be considered for addition to the <br />policyT. <br />The cinr will follo`v guidance for appropriate use as provided b�T the iVlinnesota Manual on <br />Uniform Traffic Control Devices (MN iVIUTCD). <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 conspicuityT or to increase the legibilityT of sign <br />legends and borders. <br />Prior to implementing a flashing LED sign, the following conspicuityT improvement <br />alternatives shall first be consideYed: <br />■ Install an advanced `varning sign on approach to the intersection or warning <br />condition. <br />■ Increase the size of the e�sting signage. <br />■ Install a second sign of equal or lesseY size on the left-hand side of the Yoad (if <br />allo`ved byT MN iVIUTCD). <br />■ Add one or more red or orange flags (cloth or retroreflective sheeting) above a <br />standaYd sign, with flags oriented at 45 degYees to the vertical. <br />■ Add a strip of retroreflective material to the sign support. <br />Flashing regulatoryT and warning signs shall on1yT be considered for installation in situations <br />necessitating enhanced visibilityT of the sign not accomplished byT the above treatment <br />techniques. The cityT 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 ]imited to locations where both of the following conditions e�st: <br />� <br />
