Variable Message Signs (VMS) are electronic displays that are installed at key locations along roadways and other roadways, with high-brightness display technology that ensures visibility in complex environments such as bright light, rain and fog. Its core functions include delivering real-time traffic updates such as congestion and accident warnings, safety information such as speed limits and construction warnings, and providing real-time estimated travel times for specific destinations. By allowing drivers to grasp road conditions in advance, VMS can effectively reduce traffic accidents caused by lagging information, while guiding traffic flow diversion and easing road congestion, making it a key tool for dynamic traffic management and safety.
Fixed VMS, also known as permanent VMS, is usually installed on poles or cross-road gantries on highway junctions and urban main roads, and adopts a durable housing design to resist long-term outdoor environmental erosion. This type of equipment is mostly connected to the urban traffic monitoring network, which can provide continuous traffic flow data, lane restriction notification, weather impact warning and other information 24 hours a day. It is the core facility for daily traffic order maintenance and normalized management, especially in the fixed road sections with large traffic flow, which plays a stable role in information regulation.
Vehicle-Mounted VMS is mounted on the top or side of trucks, vans and other motor vehicles, and the overall design takes into account lightweight and anti-vibration performance. The biggest advantage of VMS is its portability, which allows it to be quickly dispatched to the scene of an accident, around a large event, etc. according to temporary needs. The equipment is usually equipped with an independent power supply system, supports short-term offline operation, and can flexibly disseminate information such as temporary detour guidelines and on-site control notices, which fills the coverage gap of fixed facilities in dynamic scenarios.
As a portable sign, the VMS Trailer is mounted on a special trailer that can be towed and moved by ordinary vehicles, with a stabilizing support device on the bottom to adapt to different road surfaces. It is extremely versatile and can be used for temporary warnings during road construction or to guide large gatherings. Due to the rapid deployment, it can usually be set up and commissioned within a few hours, which makes it outstanding in emergency response and short-term project management scenarios, and can timely fill the message delivery needs in areas not covered by fixed facilities.
VMS relies on good communication systems to receive and display information, listing communication methods including wired or wireless, such as 4G modems, radio signals, local network links, etc. Remote control allows traffic operators to change information in near real time to reflect real-time changes in traffic and events. Remote control allows traffic operators to change information in near real-time to reflect real-time changes in traffic and events.
VMS utilizes a variety of display technologies such as LEDs, LCDs, etc., describing the characteristics of the different technologies, the high brightness and visibility of LEDs for outdoor use, the high resolution of LCDs for indoor and high-definition use, the advantages of LED-backlit LCDs that incorporate the best of both worlds, etc., as well as the role of customized LED display solutions. The role of customized LED display solutions.
Common power supply options for VMS include utility power, rechargeable batteries, solar panels, wind power, fuel cells, etc., emphasizing the importance of back-up power systems such as rechargeable batteries to maintain functionality in the event of a power outage or emergency.
Modern VMSs are equipped with a variety of additional features, such as vehicle detection radar that updates information based on real-time traffic flow and speed, self-diagnostic systems that monitor component performance and automatically report errors, and smart sensors and automation that improve the accuracy and relevance of information.

During peak traffic or at the scene of an accident, the VMS displays real-time information about congested roadways and lane closures, guiding drivers to change lanes in advance or choose alternative routes. Drivers can anticipate road conditions in advance, reduce the risk of emergency braking and tailgating, significantly reduce the incidence of traffic accidents, and ensure smooth road traffic.
In case of natural disasters such as earthquakes, floods or sudden crises, VMS quickly switches to emergency mode and scrolls the content of alarms and evacuation routes. The public can evacuate the dangerous area in an orderly manner through clear guidance, avoiding panic crowding and helping to maintain stable social order.
During a fire or rescue operation, VMS delineates the warning area and reminds the public to stay away from the dangerous area. At the same time, the location of rescue channels is marked to ensure the rapid passage of firefighting and ambulance vehicles, buying valuable time for emergency disposal and enhancing rescue efficiency.
At the entrance of highway and main roads in urban areas, VMS cyclically displays the speed limit standard and provisional inspection notice. Drivers will know the regulations in advance, take the initiative to regulate driving behavior, reduce speeding, illegal lane changing and other phenomena, and strengthen the effect of law enforcement and road compliance.
Around logistics parks and freight corridors, VMS updates real-time traffic congestion points and loading/unloading zone occupancy, and guides trucks to accurately dock at designated terminals. Combined with the real-time transportation schedule, VMS adjusts the order of delivery, reduces the waiting time of vehicles, and improves the efficiency of logistics turnover.

Before and after construction sections, VMS warns “construction ahead” hundreds of meters in advance, marking detour routes and speed limit requirements. Drivers slow down and avoid intruding into the construction area, which not only protects workers’ safety, but also reduces traffic friction and accidents caused by road construction.
VMSs in residential areas and alongside streets provide timely notification of water and power outages, community cultural activities, and road maintenance plans. Residents can keep track of their daily lives through daily checking and actively cooperate with the municipal government, thus enhancing their participation and satisfaction in community affairs.
During the period of high influenza incidence or epidemic, the VMS publicizes the addresses of vaccination points, opening hours and precautions for epidemic prevention. During outbreaks, VMS quickly disseminates knowledge on prevention and control, guides the public to take precautions, and helps raise public health awareness and response capacity.
At large-scale events and music festivals, VMS is distributed at entrances and parking lots, displaying the flow of the event, remaining parking spaces, and the location of emergency exits. Participants can quickly find seats and park their cars according to the guidelines, and in case of emergencies, they can also evacuate in an orderly manner to ensure the smooth running of the event.
VMS outside shopping malls and chain stores dynamically displays promotions, new product launches and store entrance guidelines. Brightly colored images and scrolling content attract the attention of passers-by, guide customers to consume in the store, and deepen the impression of the brand in the public’s mind.
VMS delivers severe weather warnings and Amber Alerts in seconds during emergencies such as rainstorms and earthquakes, and synchronizes evacuation routes in hazardous areas such as floods and fires, boosting community response by more than 40%. On a daily basis, flashing construction zone warnings and speed limit reminders alert drivers with high brightness LEDs, which studies have shown are three times more visible than static signs.
During peak hours, the VMS updates alternative routes in real time for congested road sections, guiding traffic diversion and improving the efficiency of main roads by 25%. By prompting high occupancy vehicles to use the lanes and reducing ineffective idling, the average daily carbon emission of a single roadway is reduced by 18%, and drivers’ anxiety due to congestion is significantly relieved.
In the event of a sudden accident, the VMS can update the information within 5 minutes, which is a significant advantage over the static signs that take hours to replace manually. For groups such as elderly drivers who do not use navigation, information projected directly onto the driving path fills in the blind spots of digital channel coverage.
Modern VMS can enhance information delivery through dynamic symbols and animations, such as animated arrows to guide parking lots during sports events and flashing borders to highlight events during festivals. By switching the display format at any time for different scenarios, the message reception rate can be increased by up to 60% compared to a single text.
LED light source is 70% more energy efficient than traditional lighting, and with intelligent light-sensitive regulation, nighttime energy consumption is reduced by another 30%. The solar-powered mobile VMS can run continuously for 30 days without recharging at remote sites, with a full lifecycle carbon footprint 55% lower than that of utility solutions, significantly reducing long-term operating costs.
From traffic guidance during morning and evening rush hours to emergency guidance during sudden disasters, from construction site safety warnings to shopping mall promotions, the VMS delivers dynamic and flexible information to accurately connect needs and scenarios in various industries. It not only reduces safety risks and improves operational efficiency with real-time updates, but also becomes an “information link” connecting transportation, public services, commerce and other fields by virtue of its adaptability to different scenarios. With the integration of intelligent technology, the value of this dynamic communication will continue to be extended, adding to a more efficient and safe social operation.
