Abstract
Beyond the state of the art of actual driverless systems will be presented areas of improvements and possible
innovations which may or are already taking place in the near future.
Among applications areas will be indicated new technologies trends for train control system, rolling stock,
energy savings, operation, communicating transport and maintenance.
As an example the SIEMENS CITYVAL next generation driverless system with the innovative rubber tires
rolling stock will be presented.

2. CITYVAL, NEW URBAN TRANSIT
SYSTEM.
Automation for driverless systems is a clear market
trend. Actual achievements of full automation
transportation systems make it possible to reduce dwell
time, adapt traffic to the demand and eliminate human
errors and thus increase line capacity and network
efficiency and safety.
Today these requirements of advanced passenger
service and more efficient transportation means
converge into a more global approach with the objective
to highlight over-all benefits in term of sustainable
development and reduction of carbon emission and
pollution.
Cityval, Siemens newly developed rubber tires AGT, is
following very strict roads in the area of Eco-Industrial
Design and sustainable development. This paper is
aimed at presenting these new features of our

transportation solution while focusing in three main
areas:
x
Eco-Industrial Design
x
Energy efficiency
x
Modularity and operation flexibility
But at first CITYVAL, in brief, is a complete turnkey
transport system using rubber tires trains (standard
tires), cars of 11,2 meters long and 2.65 or 2.80 meters
large, central guidance system (decreasing civil work
infrastructure) and able to carry until 30 000pphpd.
2.1. City Val Eco-Industrial Design
The sustainable development is a reference criterion for
public and decision-makers. Its principles are part of the
international commitments and are about to become an
essential part of the legal requirements in many
countries.
Cityval is designed according to the eco-industrial
development (EID) principles. Their baseline is to
integrate the needs of suppliers, designers, customers
and consumers since the design and to aim at a long
system lifespan with reduced ecological impact.
Taking into account sustainability by the eco-design,
Siemens Mobility Systems scope of work is widely
speaking the scope of a system integrator. In this
context, sustainability implies the introduction of clear
criteria and quantifiable objectives concerning the
choice of resources (materials, energy, components,
facilities, subsystems, etc.) as well as a lasting
performance.
These criteria and objectives are identified at design
phase and are incorporated in the suppliers’
specifications. Selection of each sub-system or
equipment is then widely based on the compliance with
Siemens EID requirements...
2.2. Energy efficiency
The
reduction of
consumptio
n is the
fastest
means to
reduce
greenhouse
effect gas
emission
and to
minimize
the ecological impact.
The energy efficiency is an important line in the design
of Cityval. Efforts were made at three levels: new
technologies, optimized energy management and energy
recuperation.
The vehicle propulsion uses integrated equipment that
limits the mechanical elements and increases the
efficiency by reducing consumption and saving volume
for the passengers.
The train control system, Siemens Trainguard MT
CBTC contributes to the same principle: the radio
communication decreases notably the number of fixed
components, eliminates track wiring and reduces the
maintenance effort. Furthermore, the moving block
minimizes the headway between the trains and so
increases the infrastructure efficiency.
Cityval benefits from the automatic traffic management
optimization that reduces energy by 15 to 20%. GTT the
Turin Val operator reports a reduction of about 1,500
MWhs per year equivalent to 620 tons of the CO² per
year. Cityval recovers almost 40% of the kinetic energy
when braking. The energy is reinjected into the system
to be used by another train in line. The mechanical
brakes are only applied for emergency braking saving
the wear of brake and reducing to a minimum the
particles diffusion.
2.3. Cityval modular concept
The
modular
concept
was a
major
develop
ment
focus
during product definition. The Cityval system was
designed for 1 to 6 vehicles train set.
This innovative concept handles passenger flows from
1,000 to 30,000 pphpd (passengers per hour per
direction with 4 pass. /m²) without additional
development costs.
The attractiveness of the service is one of the success
keys in an eco-industrial approach. Two major aspects
contribute to it: flexibility and quality.
The driverless CBTC Automatic Train Control provides
a very wide range of operating modes between any
stations on the line: loop operation, shuttle operation,

pinched loop operation with turnaround before or after
stations.
This increased flexibility in traffic regulation increases
reactivity to exceptional events and unexpected
transport demand: more frequent trains at peak times
and maintaining operation off peak time or “on-demand
service” at night. This adaptability makes Cityval one of
the most flexible systems available for 24/7 operation.

CONCLUSION
The design of Cityval answers concretely to the objectives
of sustainable development and has been acknowledged at
European level for its innovating character and priority
54
given to sustainable development. For these reasons, it has
been awarded development funds.
