SES America Inc.(SESA), a Rhode Island-based manufacturer of digital, LED signage for the transportation industry has been approved by the Massachusetts Department of Transportation for their Blank Out and Lane Control Signs. These models are now included in the MassDOT Qualified Traffic and Control Equipment List under Section 824: Flashing Beacons, Illuminated Warning Signs, and Lighted Barrier Arrows.
In the past ten years, the solar power industry has experienced an annual growth rate of almost 60%. At the same time, installation costs for solar technologies has decreased by more than 70%. These statistics point to a positive shift in acceptance and adoption, with a simultaneous reduction in product price.
Today, solar technologies generate enough electricity to power over 6.2 million homes. The commercial impact of solar power systems is growing at a fast rate, with 38 states in America that now have active corporate solar installs. Corporations are using solar power in distribution centers, retail stores, offices, and manufacturing centers.
Energy, in whatever form, is a key element all civilizations require in order for its citizens to not only grow, but thrive. Since the 1850's, the world (especially North America) has developed and capitalized on the opportunity of nature’s abundant resources. Over time, new tools for the extraction of assorted resources have been created and the ensuing applications have revolutionized the world’s overall quality of life, emphatically typified in the United States of America.
Many portable DMS (Dynamic Message Signs) are already powered by Solar on our roads but very few permanent DMS. Numerous misunderstanding still exists especially regarding the size of DMS that can be powered by solar, the maintenance of the system, the battery life, and the longevity of the solution.

Over the last forty years Dynamic Message Sign (DMS) or Variable Message Sign (VMS) technology for U.S. highways has evolved from mechanically operated florescent dots forming letters to present day color (Light Emitting Diodes) capable of bold, high definition images and text set on static green backgrounds and much more. In the evolution, ITS engineers have meritoriously continued the selection process of size of the sign while abetting MUTCD mandates.

Variable Message Signs like most ITS equipment needs to be maintained to guarantee reliable operation. There are two types of maintenance visits:
- Preventative maintenance
- Corrective maintenance
Defining the right type of sign for a specific project can be challenging. There are many different reasons and criteria that effect the choice of one product versus another. Designing a Variable Message Sign to solve a road safety challenge requires a thorough process and defined methodology - it is important to ask the right questions.
On one side, choosing the most advanced sign that can display anything, in any color, at any time is the easiest and most unlimited option. However, this often creates other challenges like power issues, monitoring complexity, and exorbitant costs for simple applications.
On the other side, very simple and cheap solutions exists, such as static signs with flashing beacons. Although, this can also have many disadvantages and does not solve most of the problems discussed in one of our previous blogs.
Throughout several blogs, we discussed the benefits of Blank Out Signs (BOS) and Lane Control Signs, and compared their technology against Dynamic Message Signs (DMS) and other types of signs. In this blog, we want to discuss the cost benefits of using Blank Out Signs and Lane Control Signs.
