In our quest to make roads safer for motorists and pedestrians, LED enhanced signs are being used to draw attention and deliver messages at all times. Certain areas of the country may be prone to snow, floods and other types of inclement weather. There may be a dangerous curve, a blind pedestrian crossing, a low overhead or a highwind area.How can you reduce the potential threat? Look no further than a wireless traffic control system with LED enhanced signs.
Signs with LED enhancements must comply with Section 2A.07 Retroreflectivity and Illumination in the MUTCD, which provides information on the signage regulation. LED enhanced devices innovate and redefine safety standards.
Here are a few of the most popluar:
LED Enhanced Stop Signs
The front runner in the search for safer roads was, and will always be, the static stop sign. In terms of signage, the STOP is typically the most recognizable. However, a stop sign may be difficult to notice if it is installed at the end of a dangerous curve, at a blind intersection or at a high volume traffic site.
LED enhanced stop signs are the solution, effortlessly commanding a driver's attention and raising the probability for sign recognition and compliance. According to the Federal Highway Association (FHWA), LED stops yielded a 52.9 percent reduction in blow-throughs that eliminated the potential for injury.
At times, midblock crossings and roudabouts are not visible or well-marked. Alternately, there may be improper parking restrictions in a tourist area. A 2011 Vermont study showed a twenty-three percent increase in yield-to-pedestrian data after an LED enhanced sign was installed. The result was an eighty percent total yield rate.
Increase visibility by properly installing the crossing and adding a highly conspicuous pedestrian sign. It can be actuated by push button, motion or duration. Further distinguish the crossing by adding pavement lighting to enhance visibility.
Rectangular Rapid Flash Beacon
Rectangular Rapid Flash Beacon (RRFB) LED Crosswalk Warning Systems are user-actuated LED enhanced signs that draw attention when a pedestrian is anticipating entering the crosswalk. RRFBs are under interim approval by FHWA.
Research data by the City of St. Petersburg, FL shows very high rates of motorists yielding to pedestrians, mostly in the high eighty percent range, in comparison to far lower rates (fifteen to twenty percent) for standard beacons.
Do Not Enter and Wrong Way
Do Not Enter and Wrong Way LED enanced signs alert a driver when he is traveling in the wrong direction so that he may rectify that potentially fatal mistake. If the driver continues moving the wrong way, radar detection and a snapshot can be sent to the local agency or overhead message boards to alert others to the wrong way vehicle.
Wrong way driving factored into 3.1 percent of all fatal crashes in the U.S. according to the National Transportation Safety Board (NTSB). There was a thirty percent reduction in San Antonio after installment of Wrong Way and Do Not Enter warning systems.
Curve Warning Systems
Curve Warning Systems send a wireless communication and synchronize LED signs dynamically to warn and guide motorists through a dangerous curve. This signal directs the chevrons to flash sequentially, delivering a "pull-through" effect. Curve systems reduce head-on and cross-median crashes and help to prevent and mitigate roadway departure collisions.
If you have an area with traffic issues and you can't find a way to fix it, try an LED enhanced solution. Just be sure to meet all of the MUTCD requirements.
