Smarter Cities thanks to Smart Street Lighting!
Smart Street Lighting is the natural entry point for Smart Cities hardware infrastructures!
Smart Street Lighting control
is based on deploying
intercommunicating sensors
along the streets to adapt,
in real-time, lighting levels to traffic
density and type of users (cars, cyclists
and pedestrians). Without sacrificing
security or visual comfort, Smart
Street Lighting control contributes to
minimize electrical energy consumption
and light pollution.
This is exactly the SmartNodes™
(www.smartnodes.be) design
philosophy: each street user receives a
light bubble that moves with him!
The best results, in terms of service
performance, are obtained by
dedicating to each luminary a control
module (sensors, communication with
neighbor modules and local computing
power). This confers maximal response
speed, system robustness and ease
of extension. The lighted zones are
stand-alone, but nevertheless, thanks
to appropriate gateways, they are able
to communicate with the outside world,
allowing tele-control, tele-monitoring
and embedded software upgrades.
With that approach, Smart Street
Lighting offers you a dedicated
computer network that fits precisely
to the streets network. It provides a
high resistance to failures (information
hops over a failing module), and it is
stand-alone but easily acccessible to
the outside world.
Such an infrastructure, equipped with
adequate sensors, is precisely what
is needed to acquire the information
about outdoor public space and
required to manage Smart Cities.
That information may be processed
by a common Control Monitoring
System (CMS), providing, whatever
the domain, an integrated access for
city administration and relieving it of a
multiplicity of different dashboards.
By design the system gives you the
best control of street lighting (for EACH
luminary: real-time individual control,

electrical energy consumption statistics,
monitoring of the driver and the LEDs,
etc.). Moreover, it gives you real-time
access to traffic information, sampled
under each luminary!
It is already a good entry point for the
management of mobility, a pillar of
Smart Cities, opening the way to many
applications by controlling, in the most
secure (and user friendly) way, traffic
lights, pedestrian crossings, traffic and
warning signs. All the information
needed is available through the sensors
of street lighting.
SmartNodes is also introducing a range
of remote sensors, tied wirelessly to
the SmartNodes network, with local
energy harvesting, providing a fully
maintenance-free access to other

parameters needed for Smart Cities
administration. The first applications
are aimed at: management of parking
lots by detection of free spaces,
optimization of waste collection
by remote monitoring of garbage
cans filling level, street sound level
monitoring, atmospheric pollution
monitoring, road icing conditions, etc.
In addition to their lighting function,
Smart Street Lighting networks are
the natural candidates to gather and
transfer information, measured in the
streets, for Smart Cities administrations.
That exceptional versatility largely
compensates their additional cost
compared to dimmed traditional
solutions. l
