siemens.com/mobility
Small and smart
or complex and sophisticated –
Sitraffic sX is a traffic controller
that can be both.
Setting parameters for traffic signal systems
using a smartphone or tablet computer?
With Sitraffic® sX, this is no longer a futuristic scenario: The new traffic controller can
be easily operated via the Web while meeting the highest security standards and
availability requirements. For all its simplicity, Sitraffic sX covers a wide range of
applications: It can be used as a stand-alone
solution without connection to sensors
and a higher-level traffic control system, or
works smoothly as an integral part of the
extensive traffic management system of a
large city.
The controller that started out as a smart,
basic solution can now do even more: In its
advanced version, it offers an extended
range of features and functions that allow
the implementation of solutions for challenging traffic control applications as well as
the integration of different standards.
The advanced version of Sitraffic sX:
The new traffic controller for demanding control tasks
Integrated planning and data supply via Sitraffic Office. As part of a Sitraffic
end-to-end solution, Sitraffic sX ‘advanced’ can be projected and configured in
Sitraffic Office.
PDMx control method. In the advanced version, the established and proven
traffic-actuated PDMx control method includes a library of its own.
Up to four partial nodes. In the advanced version, Sitraffic Office and PDMx allow
planning and configuration of up to four partial nodes.
VSR control centers. The advanced controller version can be linked up to traffic
computers via the Sitraffic Canto and OCIT-0 V2.0 protocols.
Accessibility – secure
communication between control center
and Web interface
For both the smart and the advanced
versions, a secure connection can be established from the Sitraffic Scala or Sitraffic
smartGuard control centers right through to
the Web interface of the controller’s processor. Hence, in terms of secure access, it
makes no difference whether you choose to
check the operating details of the controller
directly on site or from the convenience of
your office desk. For those who are looking
for a compact solution that will meet their
complex traffic control requirements or
who are planning to expand their existing
solution, Sitraffic sX ‘advanced’ offers a
range of useful new features.
The advanced version of
Sitraffic sX – now even more powerful
The new functions for “Advanced Traffic
Engineering (ATE)” and “Advanced Traffic
Management (ATM)” make it possible to use
Sitraffic sX for sophisticated advanced control, with numerous highlight functions
such as the connection of up to four partial
nodes, the PDMx control method, integrated
planning and data supply via Sitraffic
Office as well as parameterizable signal
monitoring functions. What is more, Sitraffic
sX is now also equipped for advanced
traffic management: The open system architecture enables seamless connection to
third-party control centers, using either
Sitraffic Canto or OCIT as the protocol, as
well as the project-specific implementation
of additional protocols from local development partners.

The latest in Web technology allows
easy operation of Sitraffic sX at any time
and from anywhere. The advanced
version offers a whole range of additional
useful functions that will help you
prepare perfectly for tomorrow’s tasks.
3
Traffic control made easy: Sitraffic sX
is equipped for intuitive and convenient
operation via the Internet. The easy-toconfigure controller uses modern software
architecture and features automated
data synchronization between traffic center
and controller.
4
Lean structure, easy configuration
and unparalleled user
-friendliness –
Sitraffic sX is setting new standards.
Usability – from direct Web access
to error memory
No tools, no software to install – just open
your Web browser and start using the device! HTML 5 enables easy and user
access to the Web user interfaces of the new
Sitraffic sX controller. Even customization
or the implementation of project
language packages becomes easy with modern HTML 5 interfaces. And innovative features such as an intuitive error memory are
no longer wishful thinking, but have been
developed and integrated in Sitraffic sX.
The Web user interface meets the high
requirements of IT security.
Over-the-air updates –
unique processor architecture
A processor innovation complements the
idea of remote operation: In addition to the
main CPU, a dedicated real-time processor
can take over control if required, as a kind of
“hot stand-by”. This not only maximizes
the availability of the intersection control
system, but also enables full over-the-air
(OTA) firmware updates of all Sitraffic sX
controllers in the field. Especially in times of
ever stricter IT security requirements and
breathtakingly fast hardware and software
innovation cycles, this innovative idea helps
prepare the device for future challenges.
Smart configuration –
fast parameterization of basic systems
The Sitraffic smartCore tool makes configuring a Sitraffic sX controller child’s play!
After selection of the appropriate city or
country template, the software assistant will
guide you through the entire configuration
process. The definition of the signal groups
automatically creates a topology for the
intersection that allows the user to maintain
an overview at all times, both during the
subsequent configuration steps as well as
on the Sitraffic sX Web interface.
-friendly
-specific
The tool automatically pre-generates signal
groups, detectors, output terminals and
schedules as well as signal programs and
includes them in the graphical representation. As an option, it even takes over the
parameterization of the Sitraffic sLX traffic
actuation module. Even users with little
experience or training can thus produce a
flawless configuration, including signal
monitoring, for Sitraffic sX.
Plug & play link-up to the control center –
with automatic data synchronization
The new technology also facilitates the linkup of the traffic light system to the traffic
computer. Sitraffic sX offers true “plug &
play” functionality with automated data
synchronization between traffic center
and controller. This helps eliminate frequent
error sources and ensures full data consistency within the Siemens system at all
times.
Openness – API interface
for local applications
The modern software architecture of
the Sitraffic sX controller also includes an
Application Programming Interface (API) for
connection to customer-specific applications. This interface has been developed
especially for the integration of customerspecific control philosophies and control
center link-ups as well as for auxiliary
functions such as data exchange with third-
party systems (e.g. Car2X). Thanks to this
unique, cutting-edge software architecture,
the Sitraffic sX controller is open for the
integration of additional applications and
perfectly prepared for future technological
developments.

technology, Siemens ITS is
certified to the international information security
management standard
ISO/IEC 27001. All Sitraffic
products, systems and
