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.
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.
