Beginning of Serious Vehicle Automation
Real Evolution Since the DARPA Challenges..

They’re Addressing the fact that…
We really don’t want to drive…
Addressing the fact that…
We aren’t that good…

Evolution in Transit Buses
http://www.bus2.me.umn.edu/
Objective: Efficient Utilization of Narrow Bus-Only Shoulders
Methodology: Driver Assistance via • Virtual Images,• Haptic Feedback, and • Tactile Feedback
(It Knows Enough to Steer the Bus, but doesn’t)
Bus 2.0: Initial Demonstration ofTransit-based Driver Assistance
Fleet of 10 Gillig low floor busesMorning and evening express services22 mile (one-way) travel distanceReliable travel times in all weather and traffic conditions
Bus 2.0: Transit-based Driver AssistanceHow Do They Do It?
Bus 2.0: Transit-based Driver AssistanceHow Do They Do It?
It Just Works!
• Fact: For over 40 years New Jersey has had the World’s Best “Bus Rapid Transit” System!
• It Consists of:• Efficient Boarding/Alighting @ Port Authority Bus Terminal
– 223 Departure Gates– Readily Accommodates 700 Buses/hr
The World’s Best Bus Rapid Transit System
• Fact: For over 40 years New Jersey has had the World’s Best “Bus Rapid Transit” System!
• It Consists of:• Efficient Boarding/Alighting @ PA Bus Terminal• Direct Access/Egress to Exclusive Lanes in the
Lincoln Tunnel
The World’s Best Bus Rapid Transit System
• Fact: For over 40 years New Jersey has had the World’s Best “Bus Rapid Transit” System!
• It Consists of:• Efficient Boarding/Alighting @ PA Bus Terminal• Direct Access/Egress to Exclusive Lanes in the Lincoln
Tunnel• 3+ HOV Lanes on the NJ Turnpike that are, by
default, essentially bus-only

• Fact: For over 40 years New Jersey has had the World’s Best “Bus Rapid Transit” System!
• It Consists of:• Efficient Boarding/Alighting @ PA Bus Terminal• Direct Access/Egress to Exclusive Lanes in the Lincoln
Tunnel• 3+ HOV Lanes on the NJ Turnpike that are, by default, essentially bus-only • Many Strategically Located Park&Ride Lots
The World’s Best Bus Rapid Transit System
• Pieces are Connected by:• “495-viaduct” Counter-flow Exclusive Bus Lane
(XBL)– 2.5 miles
The World’s Best Bus Rapid Transit System
• Pieces are Connected by:• “495-viaduct” Counter-flow Exclusive Bus Lane
(XBL)– Lane Segregation is by Removable Plastic Peg– Yet exceedingly Safe
» 3 (?) accidents in 41 years, no fatalities.
The World’s Best Bus Rapid Transit System
• Pieces are Connected by:• “495-viaduct” Counter-flow Exclusive Bus Lane
(XBL Movie)– Daily (6am->10am): 1,800 Buses; 65,000 pax– Peak Hour: 700 Buses; 35,000 pax– Peak Hour: At Capacity!
» Physical Driver Limit» Av. 5 sec. headway
The World’s Best Bus Rapid Transit System
– Additional Demand Exists for “BRT 2 NYC”– How to increase capacity of XBL?
• “Take a 2nd Lane”?– Political suicide!
• Widen the Viaduct and Helix?– Very expensive/disruptive
• How about Driver Assistance?– Extend Bus 2.0 Technology
Improving The World’s Best Bus Rapid Transit System
• Go Beyond Bus 2.0:– add Intelligent Cruise Control with Lane Assist to the
2,000 buses…• e.g. Daimler Benz Distronic Plus with Traffic Jam Assist• even at an incremental $100,000/bus this is just $200M
• Could achieve sustained 3.0 second headways– Increases practical throughput by 50%
• from 700 -> 1,000 buses/hr; 35,000 -> 50,000 pax/hr
– Increased passenger capacity comparable to what would have been provided by $10B ARC rail tunnel
• Institutionally manageable:– All Express Buses are leased for 1$/yr from PANY&NJ– Facilities (XBL, LT, PABT) are controlled by PANY&NJ DoT
• Ideal test facility available: – Ft. Monmouth
Improving The World’s Best Bus Rapid Transit System
• Concept Not New:
• Concept Makes Even More Sense Now!
