<br />Technology Enhanced Traffic Control Policy <br /> <br /> <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 /> <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 /> <br /> <br />Policy <br />Devices considered for use include: flashing LED regulatory (stop and yield) 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 /> <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 /> <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 /> <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 /> <br /> <br /> <br />2 <br />
