In the early 80's, the first versions of Dynamic Message Signs (DMS) used fiber optic technology which has since been improved and upgraded to incorporate LED technology. Today, the technological improvements have resulted in significant differences in the DMS market, some affecting the actual display of the message, the frequency of the message, and the quantity and placement of DMS units on a particular roadway or throughout a specific region. Some congested areas may have DMS installed in closer proximity to each other, displaying various messages, whereas more open and desolate areas may have a single DMS displaying a single, more general message.
As I travel the US attending ITS conferences and other industry events, I am often asked a familiar series of questions: What is the future of the DMS industry? Do you think DMS will become obsolete very soon ? The answers to these very good questions are not that obvious. Most people argue that newer technology will eliminate the need for DMS but reality shows a different perspective......
In most cases, contractors purchase Dynamic Message Signs (DMS) and ITS equipment from different suppliers and vendors for multiple reasons. However, we recently heard feedback from our customers who would prefer a 'bundled package' and essentially a ' one stop shop' to source all their DMS and other ITS equipment. Here are several benefits to this approach……

Blank Out Signs (BOS), due to their cost efficiency, design, and speed to market have long been employed, mostly in a MUTCD regulatory or warning sign capacity. Nationwide, there is increased attention to more situational traffic issues such as wrong way driving. Customizing designs whether in the message or actionable symbols, specialized Blank Out Sign applications are more rapidly moving up the ladder in importance with several manufacturing companies focused on furthering product development to fit industry trend for safer and simpler roadway information
On a recent trip to China related to my wife’s business, I was able to do a quick tour of ITS like Traffic signage in and surrounding the City of Shanghai, now the largest metropolitan city in the world at 24 million people.
Traffic operations professionals have long implemented Blank Out Signs (BOS) as reliable solutions to improving traffic flow, while increasing traffic safety, especially as attention grabbing warning signals in vulnerable zones or areas of recognized hazard. Prior blank out sign blogs have discussed merits of Blank Out Sign usage and applications. Given the nationally recognized need and value of blank out signs with repeated year after year growth in applied use, How do state and local governments monitor as well as control, remotely installed BOS? Ease of use, and low cost software is available for any number of blank out signs, regardless of message or use, via cloud based software.
The evolution of intelligent transportation systems has experienced in a very small window of time, the interactive communication of smartphones, more efficient data collection and tolling technologies, the better use of detection devices for warning systems as well as for transportation planning, and the early onset of market implementation of autonomous vehicles. Going back to core visceral beliefs, it is still the driver and the resulting decisions to the current transportation experience over the road that impact all of our safety. Trucking transportation best illustrates this experience.
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.
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,
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.
