What Are Variable Message Signs?

Variable message signs can display real-time information to assist drivers and inform them of traffic conditions. They can be permanently installed or portable and are operated remotely by traffic management centers.

They can help reduce rear-ended crashes by informing drivers of road closures and other issues. They are easy to read and can be changed for different events.

Real-time information

You’re probably familiar with variable message signs if you have driven on highways or traveled on public transport. These electronic signs display messages about traffic conditions or road closures. The information displayed on these signs is updated in real-time and can provide a variety of useful details. They are also a great way to communicate with the public. These signs are easy to read and can help reduce traffic congestion.

These signs can show text and graphics and effectively deliver important traffic information to drivers. They can also provide information about upcoming traffic incidents and events. They are an essential tool for traffic management and are used on highways, freeways, and motorways around the world.

Variable message signs can help to reduce accidents caused by bad weather or unexpected hazards. By providing advance warning of an upcoming lane closure, the sign can alert drivers to make alternative plans and avoid last-minute braking. This can greatly decrease the chances of rear-end crashes, which can be particularly dangerous.

VMS can also inform drivers about the location and type of incident on their roadway. The signs can be programmed to display specific road information, such as the location of an accident, upcoming construction work, or any other relevant event that may cause disruption to traffic flow. VMS can also provide traffic updates that are automatically fed from a central control center.

Several studies have shown that variable message signs can affect driving behaviors. One study examined how three levels of VMS location to route-diverging intersections and three types of VMS information format impacted driving behavior in a high-fidelity traffic simulator. The results showed that location and information content significantly influenced driver behavior.

VMS can be either fixed or portable, but they all have the same core features. They include a screen that can display text and graphics, and an integrated computer system controls them. They are compatible with other systems and can be connected to a centralized data server to collect and analyze performance data.

Easy to read

A variable message sign (VMS) is a traffic information system that displays real-time road conditions to drivers. These signs can be a helpful tool for managing traffic congestion, reducing accidents, and providing directional information. They can also be used to warn of hazardous weather or unexpected road conditions. In addition to their safety benefits, VMS signs are easy to read in a variety of lighting and weather conditions.

A VMS display is usually an LED or LCD screen that contains text, symbols, or graphics. Depending on the type of VMS, it can be either stationary or movable. Generally, a static VMS has more limited capabilities than a movable one. It is also more likely to be damaged during transportation and storage. A movable sign has the advantage of being easier to move and more flexible.

Although VMSs can be effective in reducing traffic congestion, several factors can affect their effectiveness. These include driver characteristics, such as age and visual abilities. According to research, the most important factor for understanding a VMS message is its legibility. Legibility is measured by the distance at which a message can be read. The longest legibility distances occur during midday when the sun is overhead. The shortest legibility distances occur during the evening when the sun is below the horizon, and the sign faces into the shade.

Despite these challenges, researchers have found that variable message signs can effectively influence driving behaviors. A survey of urban roads revealed that driver behavior is influenced by the type of road conditions displayed on a sign and the level of attention paid to it. Another factor that influences driving behavior is the driver’s familiarity with the road network. The findings of the study indicate that a VMS can change a driver’s route choice and driving speeds, but it must be placed strategically.

Moreover, a VMS can be used to inform motorists of road/lane closures, provide directional information, and communicate safety and accident management messages, as well as speed-related messages. These signs are useful in dispersing traffic from work areas or a potential bottleneck locations.

Easy to change

Message signs provide real-time road traffic information to commuters. This is especially helpful when lane closures, construction sites, or other events may affect traffic flow. These signs can help reduce the number of rear-ended crashes by allowing drivers to see the change in traffic conditions and respond accordingly. VMS boards can also display public service messaging, such as extreme weather warnings, evacuation notices, and Amber Alerts. They can also prompt drivers to buckle their safety belts and lock their vehicles.

InstAlert is a portable variable message sign system that is designed to be operated from the comfort of your office, home, or while traveling. It can display multiple screens of custom text, chevrons, or images and is powered by a Lithium battery, integrated solar, AC, or trailer. It can also be programmed remotely using ATS TraffiCloud web-based software.

Variable message signs can be changed quickly and are very useful in displaying important road traffic information. The information displayed on these signs can be communicated in a very short amount of time and can help to avoid congestion or accidents. They can be used to warn people about special events or conferences in the city and encourage them to take alternative routes during peak hours.

While many agencies are using variable message signs, some concerns remain about their effectiveness. One such concern is that they can be difficult to read when driving at high speeds. To address this issue, many agencies are using more sophisticated display technology. This includes LED screens with high brightness and resolution, which can be more visible to drivers at higher speeds.

Another concern is that variable message signs can be expensive to maintain. However, in some ways, agencies can save money on maintenance costs. They can use data collection tools to gather feedback on message impressions, which can then be used to improve the messages being displayed. This can also be used to determine when the message is most effective and when it is not.

Variable message signs are a great tool to have in the arsenal of any highway agency. They can be used to communicate any changes in road traffic conditions and help increase road safety. They are also a cost-effective way to deliver important information that would otherwise be difficult to convey.

Easy to maintain

VMS are an important part of the road infrastructure and must be well maintained to keep them safe for travelers. They are often located in remote areas and must be kept in good condition to avoid malfunctioning or failing due to poor weather conditions. This is why hiring a professional to maintain these signs is important. They have the experience to ensure that they are working properly at all times and can also help with maintenance if necessary.

Variable message signs (VMS) are electronic roadside signs that display a variety of information to drivers, including traffic conditions, traffic delays, and weather alerts. They are integral to modern transportation systems and can be found on most highways and urban roads. In addition to displaying information, variable message signs can collect data and provide useful feedback to transportation agencies.

The most common type of VMS is the LED sign, which uses light-emitting diodes to produce various messages and graphics. These signs can be used in a wide range of applications and are easy to read in a variety of weather conditions. They are also able to be updated quickly and easily, making them an excellent choice for roadside communications.

There are two main types of VMS: permanent and portable. Both come in a variety of sizes for different applications. Both can be easily programmed remotely and have a bright multicolor display. Permanent VMS are usually mounted on a pole or overpass, while portable ones can be installed in a vehicle. Both have many benefits and choosing the right one for your needs is important.

Both kinds of variable message signs use the latest Integrated Technology to communicate with motorists. The central control command types a message into an interface designed by Photonplay Inc, and the sign displays it on a real-time basis. It’s important to note that these messages are usually short, as they are intended for motorists who may not have the time to read them while driving.

In addition to displaying traffic information, variable message signs can be helpful for conveying public service messaging to the community. For example, they can display extreme weather warnings, evacuation notices, Amber Alerts, and reminders to buckle safety belts. They can also be used to communicate important time change information and prompt motorists to keep their vehicles fueled. In addition, VMS systems can gather data and provide valuable feedback to law enforcement agencies.
