1 SCOPE

This specification covers the requirements for an electronic message sign that can display any of the following:

• Colour regulatory symbols of minimum 0.6m x 0.6m dimensions; • 3 rows of upper case text, with each row 6 characters long.

This sign is typically expected to be used on motorway ramps placed on traffic signal posts, at times and in locations where traffic speeds are low.

This sign type may be used as a “versatile” CMS, by calling up pre-set images or text, both by a local switched input such as from a traffic signal controller, or by remote command using the defined protocol. It may also be used to display variable text or graphics, delivered via the remote protocol, although it is to be noted that its 6 character wide display limits its use in a text role. The sign does not have the display to act as a standardised VMS, in that it does not support the 18 characters per row required for that function.

Item 3.1.2 and table 3.1 in AS4852.1 [1] do not apply. They are replaced by the requirements below.

Text lines 5.17.1

Three lines, each of 6 characters.

Text Case 5.17.2

The required text to be displayed is Proportional Upper case. Lower case is not required.

Diagram explaining terminology 5.17.3

Character height 5.17.4

Minimum 165.5 mm, measured from outside edges of illuminated pixels.

Character width 5.17.5

Minimum 118.2 mm measured from outside edges of illuminated pixels. This limit applies to the normal, modal width alphabetic characters such as “S”, but not to characters such as “I”.

Stroke Width 5.17.6

Minimum 23.6 mm measured from outside edges of illuminated pixels.

Character spacing 5.17.7

Minimum 47.3 mm measured between outside edges of illuminated pixels.



Line spacing 5.17.8


Word spacing 5.17.9


Text alignment 5.17.10

Text shall be centrally aligned horizontally, within the display window.

Text Dimension principles (for information) 5.17.11

The text dimension principles used to generate the above are based on the following:

The following minimum ratios against character height were observed: character width=5/7, stroke width 1/7, character spacing 2/7, line spacing 3/7, and word spacing 4/7.

The 4/7 space between lines, and 2/7 space below the bottom line to display lower case descenders is not added, since this sign is targeted for upper case use only.

The generation of dimensional values was based on a nominal 168mm high character, with a 1.5% negative tolerance, shown rounded to the nearest 0.1mm.

Default Text messages 5.17.12

The sign shall be equipped with the appropriate default text messages for the project in the defined colours. These default text messages shall be available via both remote control and local facility switch control as ‘Message 1’ and ‘Message 2’ respectively (defined in items 3.1.6 and 3.1.7 of AS4852.1 [1]). Unless otherwise specified by the RMS Representative, these default text messages shall be the following:

5.17.12.1 The ‘RAMP SIGNAL ON’ message;

5.17.12.2 The ‘ROAD CLOSED’ message.

5.18 LED

The requirements in item 3.1.3 of AS4852.1 [1] do not apply.

5.19 LED arrangement The requirements in item 3.1.4 of AS4852.1 [1] do not apply.

5.20 Character formats The requirements in item 3.1.5 of AS4852.1 [1] are replaced with the requirement below.

One set of character formats is required, for displayable ASCII characters 32-127, similar in general appearance to the fonts in AS4852.1 [1], but modified to suit the character pixel



matrix supplied. The proposed font set shall be submitted for approval. Lower case character values shall result in display of the upper case character.

5.21 Display Changes As per item 3.1.6 of AS4852.1 [1]

5.22 Display Changes due to facility switch operation As per item 3.1.7 of AS4852.1 [1]

5.23 Display Changes due to external switch inputs As per item 3.1.8 of AS4852.1 [1] except that

A minimum of six (6) external switch inputs shall be provided (rather than the 3 5.23.1required by AS4852.1 [1]).

A common terminal for these inputs shall also be provided. 5.23.2

Switch inputs shall have 3 kV isolation. 5.23.3

5.24 External switch outputs A matching number of voltage-free contact closure outputs with that of external 5.24.1switch inputs referred to in 5.23.1, plus another two voltage-free contact closure outputs respectively for an ‘alarm’ output and a ‘service fault’ output, shall be provided.

NOTE: These external outputs permit acknowledgement to a local device(s) that has demanded a display via the switching path (such as a traffic signal controller). The number provided follows the logic of the number of inputs, plus two, these being intended for use as fault flags.

A common terminal for these outputs shall also be provided. 5.24.2

Outputs shall have a minimum of 3kV isolation, and be rated to full ELV levels, such 5.24.3that they are able to accept both 24 V dc, and 32 V ac, applied by an external device between input and the common.

Omission of these outputs may be requested on a project basis under the TS202 [9] evaluation process, with accompanying rationale, including operational and maintenance perspectives.

5.25 Electrical interfaces It shall be possible to equip or configure the control housing to accommodate the 5.25.1different control arrangement examples given in Appendix A, as suited to project requirements.



5.26 Graphics requirement

As per item 3.1.9 of AS4852.1 [1], and additionally as below:

Diameter of Circular Regulatory Symbols 5.26.1

Circular Regulatory Symbols displayed in graphics shall have a minimum outer annulus diameter of 600mm, measured from the edges of illuminated pixels.

Sign detail proportions 5.26.2

Circular Regulatory Symbols displayed on electronic signage shall closely represent the proportions of the same symbol as used on non-electronic signage, within the sign’s constraints, including consideration of stroke width.

The display pattern and overall size selected, above the minimum, shall be based upon that expected to give the best recognition. This does not necessarily mean the largest possible. Not utilising outermost pixels for the regulatory display may aid recognition where the sign is backlit, by providing an increased effective border.

The proposed display pattern defining the illuminated pixel pattern shall be submitted as part of the approval request.

Default Graphic symbols 5.26.3

Unless otherwise specified by the RMS Representative, the sign shall be equipped with the following default regulatory graphic symbols, respectively allocated as Message 3, Message 4 and Message 5 defined in items 3.1.6 and 3.1.8 of AS4852.1 [1]:

5.26.3.1 The No Entry Symbol;

5.26.3.2 The No Right Turn symbol;
