Operation (STO) : driver, onboard ATP and ATO, with semi-automatic driving, limited actions required by driver (open/close doors, failure management)

� Driverless Train Operation (DTO) : Fully automatic, attendant provides customer care and failure management (i.e. London Docklands)

� Unattended Train Operation (UTO) : Fully automatic, no onboard staff at all, optional roving attendants (i.e. Copenhagen, Thessaloniki, Brescia, Taipei, Rome C, Milan 5, Riyadh, etc…)

Main advantages of Driverless Unattended Metro vs C onventional

� 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. Theattractiveness of public transport is increased

7

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

The Driverless Unattended metro assures high performances, from technical to transportation point of view.

From Integrator to Full System Approach

Integrator : The transportation system is 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 design phase, the Transportation System is conceived as a whole and each technology gain benefits. The overall system performances are higher then achievable through a simple integration

System/Safety Approach:

10







System/Safety Approach: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 the specific O&M needs and criticalities since the beginning of the concept and design phase

O&MO&M




O&MO&M Full System Approach: in order to effectively answer to all the transportation solutions market needs, it is important to improve the System conception from theExtended to the Full System Approach , taking into account all the possible transportation system’s External Constraints during all the project’s phases (from design to O&M)

• Viability/environmental impact

External Constraints *

• Viability/environmental impact• Pollution/CO2 reduction• Eco-sustainability• Energy saving requirements• Extreme climatic conditions• Particular security requirements• Urban development needs• Passenger/Operators needs not strictly related to system performances• Video-analytics• Alarm management• And much more…

With this new vision the, transportation systems are not just the solutions to the traffic congestion but are a

living part of the city answering to the passenger and operators needs of today and tomorrow

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.
