LED traffic signs are illuminated roadside signs designed to provide information or warn of upcoming hazards to approaching vehicles. There are two main types of LED traffic signs: variable message signs (VMS) and fixed message LED signs. These signs can be permanent fixtures or temporary, mobile units for easy relocation.
VMS consist of a full screen of LEDs, allowing for dynamic changes and scheduling of messages and symbols. This flexibility enables VMS to convey different information based on traffic conditions, weather, or other factors.
Fixed message LED signs feature a specific arrangement of LEDs to display a particular symbol, message, or both. For instance, a Vehicle Activated Warning Sign (VAWS) will illuminate a “SLOW DOWN” message when a vehicle approaches exceeding the speed limit.
Both types of LED traffic signs enhance road safety by providing clear, visible warnings and information to drivers, thereby improving traffic flow and reducing accidents.
With advanced control boards and modern sign technology, both temporary and permanent VMS and fixed message signs can integrate with sophisticated software, allowing users to display real-time information. This capability is highly beneficial for traffic management. Using integrated software systems, LED signs can draw information from various data sources, such as crowd sourcing and in-situ traffic monitoring, to display up-to-date information on the signs.
For instance, if a traffic collision occurs on a highway causing disruption, this information can instantly be communicated to a VMS screen, displaying a warning hazard symbol to road users. Other warnings can include fog ahead, variable speed limits, congestion, and estimated journey times.
Additionally, fixed message VMS can be triggered by each approaching vehicle, instantly flashing to catch the motorist's attention. For example, a Speed Indicator Device can display the exact speed of a vehicle exceeding the speed limit in real time, providing immediate feedback to the driver.
LED signs stand out prominently in their environment. The bright, often flashing lights on an LED sign make the message clearer and more likely to impact road users effectively.
A Vehicle Activated Speed sign (VAS) illuminates when an approaching vehicle is traveling above the speed limit, providing immediate feedback to the driver and emphasizing the importance of adhering to speed regulations.
Safety standards also enhance the visibility of LED signs. All traffic signs from CHIANZONE come equipped with intelligent light sensors that adjust the brightness of the LEDs according to the ambient light conditions. Additionally, angled beam width LEDs ensure the light is directed onto the highway, maximizing visibility while minimizing light pollution and reducing distractions for other road users.
With a VMS, the displayed message can change with just the touch of a button. This flexibility allows a single sign to serve multiple purposes, displaying different information depending on the circumstances. For example, a medium VMS can show journey times, directions, hazard warnings, and more. These message updates can also be amended in real time, providing a significant advantage over standard static signs.
LED traffic signs offer numerous benefits, which can be categorized into three main areas: up-to-date information, eye-catching visibility, and versatility. Each factor enhances the effectiveness of the signs, offering a clear edge over static signage.
