Variable Message Led Traffic Signs Standard Highway Sign For Environmental
Â
VARIABLE MESSAGE SIGNS,
short for VMS. Â The phrase VMS is referred to exclusively
throughout the contents of this document. Â However, other
commonly used terms describing highway signs that can display
different messages are found within National and New York State
publication and policy documents. Â Examples of these terms are
as follows:Â
• VMS (Variable Message Sign) shall mean a device
to display a variety of text messages to motorists traveling the
Thruway. Â It is a traffic control device that typically
suggests motorists alter their driving in some manner and take
appropriate actions. Â A VMS is not typically used as a
regulatory sign as recognized within the MUTCD.Â
• CMS (Changeable Message Sign) shall mean a
non-static sign that supports a limited number of fixed
messages. Â An example would be the rotating drum sign used in
E-ZPass operations. Â This term is currently contained in the
***3 edition of the Federal MUTCD. Â
• CEVMS (Changeable Electronic Variable Message
Sign) shall mean a changeable message sign of a
digital/LED-LCD display type that conforms to Federal and State
statutes. Â Â
• DMS (Dynamic Message Sign) shall mean a
changeable message sign as part of the NTCIPÂ (National
Transportation Communication for ITS Protocol). Â
• BOARDS shall mean changeable message signs as
used in the Authoritys Traffic SafetyÂ
VMSÂ ApplicationÂ
Generally speaking, VMS is
used to communicate in real-time with motorists. Â VMS messages
must address current conditions on the roadway by being dynamic,
accurate, timely and understandable. When there are multiple
requests to post VMS messages simultaneously, messages will be
prioritized in the following order of importance:Â
1. Incident Management/Public SafetyÂ
2. Congestion Management/Motorist GuidanceÂ
3. Construction/Maintenance Activity Â
4. Special EventsÂ
5. Environmental Â
6. Law Enforcement MessageÂ
7. Public Service Campaign
VMS Small Knowledge:
When using text, care
should be taken that the text can be read at a sufficient distance.
One rule of thumb is that the minimum reading distance (in
metres) is about 5 to 6 times the letter height (in cm). For
example: a **-cm high letter can be read at a distance of about **0
m from the sign.Â
When planning to install new VMS, authorities should know that the
European VMS standard (EN ****6) is obligatory for all fixed
VMS signs used in traffic applications. This is not yet
the case for temporary or mobile VMS because the Construction
Products Directive (CPD) is only valid for products that are
in permanent use. An informative appendix of the European
VMSÂ standard (EN ****6) provides guidance in choosing the
correct combination of the various items mentioned
above.
