VMS is a type of electronic equipment used to convey critical messages and information, which typically consists of a large LED screen that displays graphics, text, and symbols mounted on a portable trailer, pole, or vehicle, allowing it to be easily deployed and moved to different locations as needed.
The VMS has been deployed on New Jersey toll roads since at least the s. Back then, variable message signs included static signs with illuminated text (often using neon tubes) indicating the type of event occurring, or signs using rotating prisms (tri-prisms) to change the displayed information. Since the late s, the latest LED display screen technology has been applied to VMS. This article primarily focuses on electronic VMS.
There are three main types of VMS that are suitable for different situations and scenarios.
Fixed VMS: Fixed VMS, also known as permanent VMS, is typically installed on telegraph poles or gantries on highways, roads, or urban areas to provide continuous traffic updates and control.
Vehicle-Mounted VMS: Vehicle-mounted variable message signs are installed on vehicles like trucks or vans, which are portable and can be effortlessly transported to various locations as required.
VMS Trailer: VMS trailers are portable signs mounted on trailers that can be towed by vehicles. They serve a variety of purposes and can be swiftly deployed in various locations.
Based on the characteristics and usage scenarios, variable message signs manufactured by OPTRAFFIC are divided into the following six types.
Portable Traffic Message Signs
Mobile Commercial VMS
VMS Truck Signs
TMA Traffic Signs
EU Variable Message Signs
LED Traffic Display
LED screens are often able to display information in a variety of colors and modes. The color, pattern & text are customizable based on user preferences.
Color: VMS can use different colors to convey diverse meanings or urgency levels. Variable message signs of OPTRAFFIC are manufactured in three color variants: monochrome, multicolor, and full-color.
Pattern: Bright and clear patterns and text can attract attention or emphasize urgent information. In OPTRAFFIC&#;s WEB system, there are 200+ preset patterns and texts available, and users can also customize as needed.
Overall, the colors and patterns of VMS are carefully selected to ensure clear communication of information to drivers, while maximizing visibility and effectiveness, especially in adverse weather.
VMS primarily utilizes solar energy as its primary power source. Equipped with solar panels on its top, the VMS captures sunlight and transforms it into electricity, which is stored in batteries for uninterrupted operation, even during low light conditions like nighttime or cloudy days.
Solar power allows VMS to operate uninterruptedly, reducing reliance on traditional power sources and minimizing environmental impact. There are many benefits of this sustainable energy, including low cost, high effectiveness, low carbon emissions, and high installation adaptability.
Years of experience and customer feedback have proven that OPTRAFFIC solar power VMS can operate continuously in high latitude and low light areas without the need for charging, relying on solar-converted electricity.
Variable message signs are strategically placed in different locations, such as highways, urban areas, and construction sites. After positioning, the operator selects suitable patterns on the controller and inputs relevant information such as traffic advice, road conditions, or safety instructions. Then, the data is transmitted to VMS, processed there, and finally displayed on the LED screen. The real-time information on VMS provides drivers and pedestrians with timely updates and guidance for traffic and flow management. Real-time monitoring and adjustment can ensure the effectiveness of VMS in optimizing traffic management and enhancing road safety.
VMS is widely used in various industries due to its effectiveness in conveying important messages and information. Here are the industries that use VMS.
Traffic safety: In order to improve road safety and reduce traffic accidents, VMS boards are extensively used to display crucial road information like traffic congestion, lane closures, and others to drivers and pedestrians.
Public safety: VMS boards can display emergency alerts, evacuation instructions, and other important information in natural disasters, terrorist attacks, or other emergency situations to maintain order.
Emergency service: The fire department and rescue team are also buyers of VMS boards, as they can convey safety instructions to the public in the event of a fire or other incident.
Law enforcement: Law enforcement agencies, such as traffic police, use VMS boards to display traffic laws, checkpoints, and other related information to prevent illegal behavior and promote public compliance with regulations.
Transportation and logistics: VMS boards help transportation and logistics companies manage traffic flow, guide trucks to loading terminals, and display real-time transportation schedules.
Construction: Construction sites often use VMS boards to remind drivers of road closures, detours, and construction areas to improve the safety of workers and drivers.
Municipal services: The municipal authorities use VMS boards to inform residents of community activities, road maintenance plans, utility work, and other municipal services to increase public participation and awareness.
Health department: Health departments can deploy VMS boards to communicate public health advisories, vaccination clinics, disease outbreaks, and other health-related information.
Competition & activities: VMS boards are used for sports events, festivals, concerts, and other events, providing attendees with activity schedules, parking instructions, and safety reminders.
Business: Enterprises can use VMS boards for advertising, promotions, store guidance, and other marketing purposes to attract customers and increase brand visibility.
In short, VMS boards play an important role in various industries.
The widespread use of VMS in various industries is due to its outstanding functions and advantages. Below are 6 major benefits of VMS.
Protecting pedestrians and drivers: VMS helps drivers make informed decisions and drive safely by providing real-time information about road conditions, hazards, and other traffic events. In addition, VMS can also display safety information to pedestrians, reminding them to walk on pedestrian crossings, pay attention to oncoming vehicles, or remain vigilant in busy areas.
Protecting law enforcement officers: VMS assists manage traffic flow, control speed, and enforce traffic regulations without requiring police to stand on the road, thereby reducing the relationship between law enforcement officers and potential hazards and protecting their lives.
The VMS minimizes delays and improves overall road safety by providing real-time information, promoting communication with drivers, and optimizing traffic flow, greatly improving work efficiency and traffic management efficiency.

Reduce labor costs: VMS can automatically perform tasks, such as directing traffic or updating information. A person can manage multiple devices simultaneously and solve multiple situations through OPTRAFFIC&#;s WEB system. VMS significantly reduces labor costs related to traffic management.
Lower infrastructure costs: Compared to traditional static signs, portable VMS requires less infrastructure investment. It can be easily installed and moved to different locations as needed, eliminating the need for expensive permanent installation.
Solar energy and low energy consumption: VMS are generally equipped with solar panels to reduce reliance on traditional power sources. In addition, VMS adopts energy-saving LED technology to minimize energy costs.
VMS was designed with portability and flexibility in mind, vehicle-mounted VMS and VMS trailer can be easily transported and deployed in different locations.
Portable VMS is typically used for temporary activities or emergencies, such as road construction, accident sites, or building areas, as it can be easily towed to a location, quickly installed, and adjusted as needed for quick response. Portable VMS can also be deployed in remote areas where permanent infrastructure may be impractical.
Actual usage data proves that VMS manufactured by OPTRAFFIC can be deployed by a single person within five minutes.
