C ross Zlín develops, among
other products and
services, adaptive traffic
control for urban areas. This
includes smart systems to
control traffic via traffic signals,
speeding up traffic by using a
road’s maximum capacity, and
providing drivers with live
traffic information in their area.
Many modern systems for
traffic light control are ‘fed’ data
about the number of cars
passing through intersections.
Information about their speed
and class, or other attributes
such as public transport or
emergency vehicles, may be
input too. This applies to Cross
Zlín’s system too. For example,
its fourth generation of traffic
signal controllers, Cross RS4,
and its eDaptiva adaptive
control system can be connected
with an unlimited number of
traffic detection elements and
other available data in order to
set up the best traffic scenario in
real time.
Information – about travel
times, accidents, road closures,
warnings and more – can be
made more useful if shared with
drivers. Imagine if a smart city
platform integrated all of these
and processing data from
numerous sources – from traffic,
weather stations, parking space
and parking lots – directly into
roadside equipment.
In the future, traffic data
from numerous devices and
systems will become
increasingly integrated and
aggregated into useful
information that can be shared.
Currently, isolated systems are
becoming more integrated with
one another and they are
capable of interacting with each
other in real-time. By adopting
a progressive approach toward
traffic management, universal
road technology and a smart
integration platform, the
benefits of traffic management
in a smart city can be realized.
final destination, but are unable
to find a parking space.
Therefore, the time that you
saved during your congestionfree
drive is lost due to trying
to park. How can city planners
solve this issue? By monitoring
parking space occupancy so that
it is possible for drivers to
navigate to parking lots with
available spaces; and by using
parking time data and statistics
(including overstay times a
time limit applies) to set up a
smart parking strategy in the
area. This parking data could
also be integrated into a smart
city platform.
InVipo is flexible and open
smart city platform. It delivers
integration and interoperability
for smart cities. Data from
various systems are
interconnected by InVipo into
a single system with intuitive,
user-friendly outputs and
effective control.
Universal dataloggers, also
known as road-side control
units, are capable of integrating

datasets into one. The result
would be real-time traffic data
from signalized intersections
that could be used for other
applications – for example,
calculating travel-times. This
information could then be
shared with drivers via variable
message signs, car navigation
systems, mobile apps and
the radio.
There’s also the case of
parking. Imagine: travelling
seamlessly through a city and
only encountering a few short
stops at traffic signals, rather
than traffic jams, thanks to
smart traffic systems as
described above. You reach your
