How to Choose a Variable-Message Sign: Tips and Considerations.

Variable-Message Signs (VMS) are electronic display boards that provide traffic information and other relevant messages to drivers on the go. They are commonly used on highways and roads to inform drivers about weather conditions, traffic congestion, road closures, and other events that could affect their travel time. VMS are an essential tool for effective traffic management, and selecting the right message sign can be a daunting task. Here are some tips and considerations to help you make an informed decision.

1. Purpose of the Sign.

The first thing to consider when choosing a VMS is the purpose of the sign. What is the primary message you want to convey to drivers, and how often will you need to change the message? Some VMS are designed for permanent installations, while others are more suitable for short-term or mobile applications. Determine the number of lines and the size of the display board needed to provide the desired message.

2. Location of the Sign.

The location of the VMS is another crucial factor to consider. Will the sign be placed in a high traffic area? Will the sign be exposed to harsh weather conditions? These factors will influence the type of display board and protective casing needed to ensure the durability and readability of the message.

3. Message Capabilities.

The message capabilities of the VMS are also essential to consider. Some signs are capable of displaying text, graphics, and animations, while others are limited to text-only messages. Determine the level of complexity needed for your message, and choose a sign with adequate capabilities.

4. Visibility and Legibility.

The visibility and legibility of the message are crucial for the effectiveness of the VMS. A good VMS must be easy to read, even from a distance. Consider the brightness of the display board and the type of font used for the text. The contrast between the background color and the text color is also essential to ensure readability.

5. Communication Protocol.

The communication protocol used by the VMS is also vital to consider. Different signs use different protocols, such as serial communication, Ethernet, or fiber optic. Choose a sign with a protocol that is compatible with your existing communication infrastructure to avoid compatibility issues.

6. Software and Programming Capabilities.

The software and programming capabilities of the VMS are also essential to consider. Some signs come with proprietary software, while others are compatible with standard programming languages such as Java or C++. Determine the level of customization needed for your message, and choose a sign with adequate programming capabilities.

Closing Dialogue.

In summary, selecting the right VMS requires careful consideration of various factors, including the purpose of the sign, location, message capabilities, visibility and legibility, communication protocol, and software and programming capabilities.
