4 Easy Steps to Choose the Right Size of your DMS

Posted by Phil Perut on Nov 10, 2017 9:51:54 AM

We have created this additional reference to follow our last blog, defining the right size of dynamic message signs In most cases, DMS users already know what they want to display and what messages or graphics will be needed in order to do so. Today, most DMS are full matrix, making it very difficult to determine how many lines and characters a DMS is capable of displaying. This blog helps answer these questions and provides a 4 step procedure to help choose the right dimension of the display area, in addition to some tips like what fonts to use.

Managed Lanes: Optimal Application for DMS with Custom Options

Posted by Mike McKay on Nov 7, 2017 7:42:05 PM

 

With the continued burden of finding funding sources for US urban roadways construction and maintenance, state agencies and regional transportation commissions are employing segmented toll opportunities which often require little infrastructure adjustment- converting urban freeway High Occupancy Lanes to income producing toll lanes,  commonly known as managed lanes. The challenge faced by DOT is to inform drivers of the rules applicable to the managed lanes. Are the lanes open? What is the toll rate? The only way to inform all drivers is to use Dynamic Message Signs,

Getting to Perfect: True Compliance to MUTCD on Variable Speed Limit Signs

Posted by Phil Perut on Sep 25, 2017 8:03:21 AM

 

In the past, we’ve blogged the proper use and application of Variable Speed Limit Signs on U.S. highways as it pertains to use relative to either traffic or weather conditions. Highlighted were typical designs and regulations with options regulatory agencies employ in color and size of the overall sign, both for the static and the LED aspect of the sign. In the majority of applications however, typical 12 or 18” characters employed fall short of MUTCD full compliance.

How to Define a Good Variable Speed Limit Sign

Posted by Phil Perut on Apr 3, 2017 1:30:00 PM

 

State DOT highway Intelligent Transportation Systems (ITS) are progressively capitalizing on comprehensive Variable Speed Limit (VSL) designs. As a more advanced and timely safety warning system, changing the speed limit based on weather or traffic conditions in focused locations offers more precise warning to stretches of especially vulnerable roadways. In often non-negotiable winter road conditions, unreliably slippery roadways require more precise, distinctly locational, lower speed limit advisories. Ideal weather conditions of summer, not so much. Variable speed limit systems are continually proven ITS safety devices in such states as New Hampshire, Wyoming, Minnesota, and Utah.  The VSL Subscribers list continues to climb as a cost effective, dynamic messaging system, in particular with rural locations.

VSLs foster opportunity for DOT’s to utilize accurate placement for both regulatory and warning applications. Serving as warning signs with amber colored characters in particularly hazardous locations, the dynamic aspect of posting variable speed limits or for that matter, blanked out signs, creates a positive and engaging interface with the driving public. Applied as a regulatory sign, VSL’s with white characters bring into play stricter standards with law enforcement options.  Excising proper design criteria, these signs can meet MUTCD standards for lettering in sizes 12 to 18 inches.

How To Calculate An Optimized System for Solar Powered Dynamic Message Signs

Posted by Brandon Tessier on Jan 9, 2017 11:00:00 AM

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.

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.
