8/14/2023 0 Comments Traffic signs ncRRFBs are not traffic signals, and are not intended to stop vehicular traffic at a pedestrian crossing. When activated, the beacons flash in a wig wag pattern, enhancing pedestrian visibility by alerting drivers on the road of their presence. Rectangular rapid flash beacons (RRFBs) are used as warning devices for vehicular traffic at select pedestrian crosswalks. The Town of Apex maintains all crosswalk flashing beacons within corporate limits and extra-territorial jurisdiction. Town of Cary maintains some of the beacons found along the border of corporate limits. Otherwise, the school calendar is programmed in advance. Adjustments are made to the times of operation for special events when staff are notified by the school system. They operate in a flashing pattern for a set duration before and after the school bell times. These beacons are placed along routes where school zones have been established to warn drivers of school activity during school start and end times. The Town of Apex maintains most of the school zone time of day flashing beacons within corporate limits and extra-territorial jurisdiction. Preemption provides a green light to the prioritized movement as intended to aid emergency response efforts. The Town of Apex maintains preemption equipment within traffic signals at select locations to prioritize emergency vehicles. Traffic signals are primarily intended to reduce delays for high volumes of traffic on conflicting approaches over extended periods of time that could not otherwise be managed efficiently by stop signs. In some cases, installation of a new traffic signal or changes to an existing signal may actually result in an increase in crashes, although it may change the types of crashes occurring most often. Traffic signals are traffic control devices and do not necessarily reduce or prevent crashes. Costs typically range from $120,000-$350,000 per intersection depending on the size and type, with geometric improvements adding substantially more cost where requiredĪny intersection where at least one of the roads is a state-maintained road cannot be signalized until NCDOT finds that the signal is warranted and permits the design and installation to proceed.NCDOT Division Traffic Engineer may/may not approve location for signalization – applies to all state-maintained roads and/or where a signal would be connected to a nearby NCDOT timing system and/or require railroad preemption.NCDOT may propose to design and fund a traffic signal as a safety improvement project on state-maintained roads subject to crash history and limited funds.Town identifies potential public funding source or private development responsibility in a proposed or previously approved plan.Warrants met – traffic signal is recommended for installation may also require geometric improvements subject to traffic analysis.
