7 Myths About  Solar Powered Dynamic Message Signs

Posted by Phil Perut on Nov 21, 2016 9:00:00 AM

 

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.

Let the Message Guide the Size of Your Variable Message Sign

Posted by Mike McKay on Nov 14, 2016 9:00:43 AM

 

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.

6 Criteria To Decide if a LED Blank Out Sign Works For Your ITS Application

Posted by Emily Boissonneault on Oct 18, 2016 3:30:00 PM

  

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.

Discover the Environmental Standards Defined by NEMA TS4

Posted by David Connolly on Sep 16, 2016 10:00:00 AM

We recently published a blog about the 5 Display Properties Defined by NEMA TS4 and are continuing with our series referencing these specifications for Dynamic Message Signs (DMS). This installment will examine the Environmental Requirements described in Section 2 of NEMA TS4 that establishes the limits of operational conditions in which the DMS must perform. They are also intended to make sure the DMS is delivered in good condition.

VMS Pricing vs Value: 7 Considerations When Assessing Your Priorities

Posted by Mike McKay on Aug 15, 2016 2:00:00 PM

In the last 40 years, since dynamic messaging signs became an integral part of the U.S. highway’s persona, the industry has gone from flipping mechanically iridescent orange dots to advancing fiber optic designs, and now, LED lighting.  With continued advancements  in solar due to greater energy efficient design and product with ventilation or cooling systems are no longer necessary.  Trending along with LED advancements is the critical need for agencies to maximize their purchasing power while still acquiring ITS devices that truly match their most recent concerns in the field and on paper.  As a result agencies are looking towards value versus finding the lowest VMS pricing in contract assessments.

Vision Zero:  The Human Approach to Road Safety

Posted by Phil Perut on Jul 20, 2016 1:00:00 PM

The Center for Disease Control and Prevention (CDC) reports that over 32,000 people are killed and more than 2 million are injured every year from motor vehicle crashes. That works out to roughly 90 deaths each day across the United States - with one third involving drunk driving and almost another third involving speeding. In order to combat such a staggering number of transportation-related casualties, federal and state “Vision Zero” (known in the U.S. as 'Towards Zero Deaths') initiatives are being rolled out to achieve a future where there are no fatalities or serious injuries in road traffic.

4 Reasons DOTs Should Power Travel Time Data Through the Cloud

Posted by Phil Perut on Jul 1, 2016 1:49:10 PM

Since the late 1920’s, engineers and planners have conducted travel time and delay studies to unravel the intricacies of transportation. With the instatement of the revolutionary Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA), flexible state and local programs were developed to address urban, suburban, and rural congestion. Travel time, a key performance measure in congestion management systems, is one of the few ITS concepts readily understood and communicated by everyone from your local news reporter to the daily commuters in the trenches.

How to Choose the Best Dynamic Message Sign Manufacturer

Posted by Phil Perut on Jun 24, 2016 1:30:00 PM


When considering a DMS Manufacturer, there are a variety of factors to take into account. You might be inclined to choose a manufacturer strictly based on cost, but have you truly done your due-diligence? Entering into or accepting a bid with an under performing DMS manufacturer can have serious consequences - consequences that outweigh upfront savings. 

 

Take a look below for the eight criteria we believe defines an outstanding DMS manufacturer:
