Tern Symbols for LED-Variable Message Signs (VMS)
The Tern Symbol templates available here are provided in 4 dimensions which are governed by Austrian law. Please check if these dimensions can be applicable in your country.
Abreviations in the file names provide a multitude of information
TS0330 = Tern Symbol No. 0330
LED = TS for use on VMS with Light Emitting Diodes (LED)
64x56 = width and height of the image (in pixlel/LED)
b4 = border-strokewidth (in this case red and triangular) measured in pixel/LED
d16 = distance between LED in the matrix, measured in millimeter
ldd4 = distance between lit dots (lit LED), measured in pixel/LED
LDD governing viewing distance/time and speed
LDD2, the minimum distance of 2 pixel/LED gives a Symbol 100 m viewing distance
LDD3: 200 m viewing distance
LDD4 and above: more than 200 m viewing distance
Speed: LDD3 and above are recommended for roads laid out for speeds of 130 km/h. TS with LDD4 and above are recommended when more than one symbol is shown on a VMS, or longer viewing time or greater viewing distance is required. LDD2 should not be used on roads or road sections laid out for more tham 100 km/h.
Tern Symbol Templates for LED-Variable Message Signs (VMS) are provided as .BMP-files, ready for use. Additionally, an .XAML-file provides the symbol in vectors, for integration to generally represent the symbol in the software used for administration of content displayed on VMS.
Please note that the .XAML-file is not applicable for regular road signs, as their visibility requirements differ greatly from LED-signs. Instead, look up the Tern Symbol for "vectors", bearing the same TS-number (e.g. TS0330).
Maximum visibility of information on signs – improving road safety and fostering inclusion
Tern symbols are crafted to provide maximum visibility of visual information, despite difficult circumstances, such as movement at high speed, short viewing duration, long viewing distances and bad viewing conditions. This is crucial for adequate information perception in vehicular road traffic, as well as for citizens effected by visual impairments to profit from inclusive information.
