The number
of automobiles expands exponentially. City roads and highways witness traffic
congestion that has become more the norm than an exception. For authorities,
controlling traffic is a nightmare and, in future, the problem is bound to
escalate. Traditional methods of traffic control and management no longer work.
Safety of drivers as well as others is at risk.
Variable message system is
the key to better and dynamic traffic management. ITS based VMS variable
message signs adapt to changing traffic patterns. Feature rich, these VMS
sign for speed warn, guide and inform drivers on highways as well as on
city streets. These LED based digital signage systems incorporate into
existing computer networks or can even operate independently in the form of portable
variable message sign systems that can be deployed with ease in case of
need. Such tied or independent VMS led screens are used to designate
lanes, for emergency warnings, for traffic updates, to warn motorists about
tunnels, toll booths or roadblocks ahead. Digital LED Screens can also
be set up in vehicles to take care of temporary requirements. These computer
controlled VMS LED screens can be programmed to display messages with
automatic adjustment of brightness according to ambient conditions. Another
modern traffic aid are radar based VMS sign boards that warn drivers
about their vehicles’ speed and also display the safe speed limit for that
specific zone. All these products are the present and future of dynamic traffic
management of congested city roads and highways, bringing order into chaos.
How are
these VMS variable message signs better than traditional signage? For
one, they employ high brightness flashing LEDs that are strikingly visible even
in bright sunlight. Whereas passive signs tend to be ignored, these LED screens
catch the attention of motorists. Since messages can be customized according to
conditions, these are more helpful for drivers to warn them about, say,
landslide ahead or traffic jam or a bridge. In time, it will become a habit for
motorists to check such variable message sign displays. Since their vehicle’s
speed can be displayed on these traffic message signage the motorists will also
make a conscious effort to keep within safe speed limits, thus reducing dangers
to pedestrians and risk of accidents to their vehicles. For the authorities these ITS enabled VMS
signage help gather data that will help them develop strategies to reduce
congestion, that will, in turn, help reduce fuel consumption and levels of
pollution.
