Variable Message Signs: Tips for Hiring the Best
These days, more creative and efficient methods are used to display information. For instance, variable message signs (VMS) are a preferred choice for displaying information to all motorists on the road. Some of the common areas where they are installed include overhead beam structures, roadway shoulders, and full-span overhead sign bridges. In addition, they are suitable for temporary notices such as notifying motorists of temporary road construction, repair, or maintenance works. They display real-time information that can be altered as wished according to the situation. That said, information displayed on them allows motorists to be keen so as to avoid incidents or to get travel directions.
Having noted the areas of use for variable message signs, it is crucial that a person hires the best according to the type of information to be displayed. This means that there are different types of VMS. First of all, the most common VMS are referred to as freeway VMS and are mainly used on highways. They are large in size for easy visibility since they are best suited for highways where motorists travel at high speeds. The display area is comprised of two display areas including a pictogram and a message are that is normally in an alphanumeric format.
Since freeway variable message signs are not ideal for all places, we have a second classification that is comprised of tactical VMS. These signs are generally designed to help motorists understand the core reasons behind lane closures or recommended lower speed limits. Size wise, they are a little bit smaller than freeway VMS, and they typically display messages in yellow color.
At last, there are the arterial variable message signs that are best suited for arterial road networks. They require proper positioning since the messages displayed on them often requires motorists to respond to the displayed message. Since the three types of variable message signs are not the exclusive ones in existence, others such as changeable message signs exist though they are exclusively used on short timespans where they are required to inform motorists for a short while after which they are removed.
Once the type is established, people willing to hire VMS must inquire further information regarding the individual characteristics of each to evaluate its usability or ease of use. Powering VMS’s should be a pressing issue as you have to ensure that you are in a position to use the one you hire without having the power getting depleted or expensive to provide; therefore, it is economical to use solar-powered VMS’s. Besides, various programming options should be available such as via SMS, laptop on site, or internet.
