Variable Message Signs

SOlAri VAriAble MeSSAge SignS
Variable Message Signs (VMS) are a
proven technology as the most effective
means of communicating real-time traffic
information to drivers. The introduction
of VMS technology has significantly
contributed to the increase in traffic
safety on roads and highways. Another
advantage of implementing an advanced
VMS solution is that it may also be used
to suggest alternate routes to drivers in
order to alleviate heavy congestion conditions.
Devices types
Intended application
Solari VMS products are compliant with
all International standards and may be
used in any traffic application, including
highways, toll stations, road and city information.
Several models are available to address
different application requirements, including
alphanumeric models (for general
purpose messages), full-graphic/
full-color models (to display road signs)
and semi-graphic models (for non-
Western languages such as Arabic).

AlphAnuMeric VMS
Alphanumeric and full-graphic
VMS are often combined
in order to convey different
types of information.
In the example above
(GRA, Roma) a full-graphic and
full-color VMS displays
road signs, while the
alphanumeric VMS
provides supplementary
information.

SeMi-grAphic VMS
Semi-graphic solutions
are useful for applications
that require support for
non-Western character sets.
A typical example is the
Arabic language, which requires
a continuous stroke:
in such a case, character-based
LED modules cannot be used.
The picture shows an
application in Kuwait.
Solari was the first company to ever install a Public
Display System (Liege Railway Station, Belgium 1956)
and the first VMS System with LED technology (Udine
City Information System, Italy 1989).
With over 50 years of experience in the field,
Solari is the worldwide leader for the supply of
turnkey information display systems.
Full-grAphic VMS
Full-graphic solutions are
suitable for applications where
there is no pre-defined layout
for the information to be
displayed to drivers.
The VMS shown in the picture
above (No Regrets System in
the Nederland) provides a
full-graphic surface with
support for two colors
(white and red).
lcS And SlS
Lane Control Signs (LCS) and
Speed Limit Signs (SLS)
should be referred to as
Changeable Message Signs
rather than VMS.
They are specialized devices
that display a very limited
number of pictures. Nonetheless,
they are much cheaper than fullgraphic
solutions where each
pixel is individually addressable.

uggedized enclOSureS
Solari VMS are deployed with ruggedized enclosures which are suitable
for installation in any type of environment. Special care is paid
to temperature and humidity control, in order to avoid malfunctions
and condensation on front surface. The ambient temperature
is measured by multiple sensors and, according to preset rules which
implement a hysteresis cycle, cooling/warming devices are activated.
The enclosure is based on an aluminum extrusion and provided
with back doors for maintenance.
SOFTWAre
A very powerful, yet simple to use application is available to control
multiple VMS devices. This application implements a full traffic
management software including Graphical User Interface with GIS
with the ability to interface others systems such as Scada Systems.
Solari SW is a client-server application featuring a Microsoft Windows
graphic user interface. The main window contains a map of
the VMS system showing the location and the status of each device.
By clicking on an icon representing a VMS, it is possible to obtain
a detailed view including a real-time picture of the message that is
currently displayed on the selected VMS. The detail form also allows
the operator to select a new message, to change working parameters
for the VMS, and more. The FEP also allows the operator to handle
scheduled messages through a tool named Scenario. Additional
functions include a reporting utility, the management of vocabularies
(lists of pre-defined messages, city names, etc.) and a configuration
utility.
