7. Main advantages of Driverless Unattended Metro vs Conventional
Lower O&M expenditure due to a significant decreasing of the staff, as drivers and on
board personnel are not required
There are additional savings in operating costs, since the system is operated in compliance
to an optimum fully automated specification reduction of energy consumption, components
wearing, spare parts, etc…
Trains can be shorter (no cabs) and run more frequently without increase expenditure for
staff
The metro Operators are able to often and easily vary the service frequency to meet
sudden and unexpected transport demands, without increasing the staff costs
High level of performance, availability and reliability. Headway down to 75s. The
attractiveness of public transport is increased
High quality of service with high frequencies, even when the tickets incomes don’t justify
the operation, without increasing the staff costs
Driverless metros are safer than conventional (most rail accidents are caused by human
errors)
Large benefits in terms of safety and comfort thanks to the Platform Screen Doors
Train turnover time at terminals is extremely short as trains go into the holding track and
returns immediately reducing the fleet size needed for operation and consequent savings
in terms of investment and maintenance costs

10. From Integrator to Full System Approach
Power Rolling Integrator: The transportation system is
Signalling
Supply
Telecom
… Stock conceived just assembling a certain number of
technologies. It has low performances and it’s not
suitable for high technology and complex applications
System Approach: since the beginning of
Civil Power Rolling design phase, the Transportation System is
Works
Signalling
Supply
Telecom
… Stock conceived as a whole and each technology gain
benefits. The overall system performances are higher
then achievable through a simple integration
Civil Rolling
System/Safety Approach:
Power
Works
Signalling
Supply
Telecom
… Stock System Approach should focus on safety for more
reliable, safe and with higher performance than a
generic System Approach
Extended System Approach:
Extend the system approach, taking into account
Civil Power Rolling the specific O&M needs and criticalities since the

O&M
to effectively answer to all the transportation
solutions market needs, it is important to
improve the System conception from the
Extended to the Full System Approach,
taking into account all the possible
transportation system’s External
External Constraints* Constraints during all the project’s phases
(from design to O&M)
• Viability/environmental impact
• Pollution/CO2 reduction
• Eco-sustainability
• Energy saving requirements
• Extreme climatic conditions With this new vision the, transportation systems are
• Particular security
not just the solutions to the traffic congestion but are a
requirements
* • Urban development needs
living part of the city answering to the passenger and
• Passenger/Operators needs not operators needs of today and tomorrow
strictly related to system
performances
• Video-analytics
• Alarm management
• And much more…

14. Exemple of unattended Metro in the GCC:
Princess Noura University for Women
The first Driverless Unattended Metro in the Kingdom of Saudi Arabia
In the North of the Saudi Capital Riyadh, a huge site is under construction in order to
host the biggest University in the world in one single site.
The PNU-APM, is a 11.5 km of high technology serving the whole campus of the
university and enabling the students to access easily to each part of the campus
(faculties, housing, recreation areas, etc…). The line is completely on viaduct, has 14
stations and is characterized by a central loop of 6 km.
