Driverless Railway Transportation System

Nasir Khan, Layne Orr, Max Altshuld, Ryan Hinds, Matthew Lee

Overall System ConceptDriverless Railway Transportation System

◦ Beijing International Airport to Olympic events• Connects with existing Beijing subway system • 4500 passengers/train/hr @ 100 km/hr (62.5 mph)• Airport to downtown Beijing—16 minutes• 28 Mile Link—above and below ground

◦ Transport passengers safely and efficientlyAdvanced Technology

◦ Bombardier—Driverless Advanced Rapid Transport Technology (ART)

◦ Tadiran Telecom—Internet Protocol-based control system

◦ Video screens—latest news and Olympic stats

System Boundaries Bombardier trains Railway tracks & support infrastructure

◦ Below ground• Tunnels, ventilation, & emergency lighting

◦ Above ground• Bridges, traffic crossings & signaling systems

Ticketing—online, kiosks & teller stations Passenger platforms & stations Operations

◦ Control room, maintenance & security facilities Emergency back up power system

Electricity controls train functions.

Suspension calibration depends on structural system.

Backup needed for almost all

components.

Life Cycle Needs & Functions

Development◦ Control system interface with existing

infrastructure◦ Train route and traffic control

Manufacturing/Production/Construction◦ Tracks, cars, ticketing & support facilities◦ Road crossings, tunnels & bridges

Deployment◦ Material deliveries—construction & equipment◦ Assembling railway system on-site

Operation◦ Ticketing system & live update video feeds◦ In-service, emergency, w/ & w/o passengers tests

Life Cycle Needs & Functions

Support◦ Preventative maintenance—tracks, cars,

infrastructure & ticketing system◦ Train car status & control system diagnostics

Disposal◦ Repair parts—bearings, wheels, electronics, rails◦ Train cars—refurbish, replace & recycle

Training◦ Control—operational, ticketing, S/W & H/W◦ Inspection/Service—cars, tracks & infrastructure

Verification◦ Safety & “performance against schedule” metrics

Advanced Technologies Bombardier

◦ Advanced Rapid Transit Technology (ART)◦ Fully automated and driverless◦ ART 300 lightweight aluminum vehicles◦ Linear Induction Motors (LIM) for propulsion

Tadiran Telecom Control System◦ Internet Protocol-based communication◦ Multimedia messaging◦ Computerized attendant◦ Disaster avoidance & E911

Emergency Backup System◦ Cars, control, & infrastructure

Technical Risks Building the 28 mile long railway

◦ Manage subcontractors, quality control, & integration Technology transfer

◦ Concept is complex—needs a variety of new technologies to meet project goal

Design & construction complexity◦ Many engineering disciplines needed, complex

subsystem interfaces, & passenger safety issues System integration

◦ Tadiran, Bombardier & Beijing Trans. Authority Technical interfaces

◦ Complex system, many subsystems are cross-discipline & different design teams/contractors

Risk Priority & MitigationPriorit

y Risk Impact Mitigation*

1Design &

Construction Complexity

Prob.: HImpact:

H

Full audit to ensure compliance with Beijing construction codes versus railway

requirements. Special analysis, testing & fallback alternatives.

2 Technical Interfaces

Prob.: HImpact:

H

Special analysis and testing, relief of excessive requirements, fallback alternatives for risky

interfaces (use less risky technology).

3 Technology Transfer

Prob.: HImpact:

M

Start process with government agencies early. Fallback alternatives, analysis and testing on

new technology with rapid prototyping.

4 System Integration

Prob.: MImpact:

H

Training and inspection program development with local engineers and operational personnel

at least 1 year in advance. Integration specialists & fall back alternatives.

5 Building the Railway

Prob.: LImpact:

H

Special analysis and testing. Subcontract this task out to companies with the right

experience.* Technical/management reviews should occur as a mitigation plan for

each of these risks.

Context Diagram

Safety ART is safer than automobile travel

◦ 24x fewer fatalities per passenger mile Issues

◦ Braking/Propulsion• Safe travel—depends on correct speed & timing

◦ Entry/Exit• Incorrect door timing—may injure passengers

◦ Environmental/Temperature Control• Underground & rail car extremes must be moderated

◦ Collisions/accidents• Communication—data transmission failures• Railway/Traffic crossing impediments

Networks subject to malicious attacks◦ Moving trains require wireless networks—less

secure◦ Solutions• Multiple networks• Strong encryption & passwords

Physical threats—crime & terrorism◦ Potential danger in major cities (eg. Beijing)◦ Solutions• Infrared sensors surrounding tunnels• Cameras & video surveillance• Security checkpoints at subway connector stations

Ticketing◦ System must ensure patrons pay for rail usage
