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.
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.
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.
