Transit and Autonomous Vehicle Technology
• Impact of Self-Driving Cars on Transit • Opportunities for Autonomous Driving
Technology in Transit
• Our proposal to FTA
How Autonomous Cars Will Affect The Market for Transit
Transit riders generally fall into two categories, captive and choice • Captive riders – cannot drive or do not have access to a car • Choice riders - generally do own cars, but choose transit
when it can offer a faster, cheaper or more convenient trip. Choice riders can avoid congestion, use time on transit to read, work or sleep, and can avoid parking costs and hassles at their destinations.
Automation Coming in StagesNHTSA Preliminary Policy on Automated Vehicles
Level 2 (Combined function automation) • Automation of at least two control functions designed to work in harmony
(e.g., adaptive cruise control and lane centering) in certain driving situations.
Level 3 (Limited self-driving) • Vehicle controls all safety functions under certain traffic and environmental
conditions. • Driver expected to be available for occasional control. Example: Google car Level 4 (Full self-driving automation) • Vehicle controls all safety functions and monitors conditions for the entire
trip. • Vehicle may operate while unoccupied.
Functional Capabilities of Currently Available Commercial Collision Avoidance
and Driver Assist Packages for Autos
• Adaptive cruise control• Adaptive headlights• Autonomous emergency
braking• Blind spot detection• Cross traffic alert/avoidance• Driver fatigue/inattention
alert• Forward collision avoidance
• Lane departure warning• Lane keeping assist• Parking assist• Pedestrian
detection/avoidance• Rear collision
warning/mitigation• Self-parking• Side impact detection
These Systems are Reducing Claims
Vehicles rated “Superior” in front crash avoidance by the Insurance Institute for Highway Safety
• Cadillac ATS sedan and SRX crossover-utility vehicle
• Mercedes-Benz C-Class sedan• Subaru Legacy sedan and Outback wagon• Volvo S60 sedan and XC60 crossover
Impact of Level 2 Technology - Cars
Key Features• Jam assist• Adaptive Cruise Control• Lane-keepingLikely Impacts• Fewer crashes• Lower Stress• Some increase in auto commuting trips
Google Self-Driving Car (Level 3 Automation)and Someone Who Really Needs One!
Impact of Level 3 Technology - Cars
Key Features• Automatic Valet Parking• Limited Self-driving – freeways, pre-mapped or
programmed routes, good weatherLikely Impacts• Significant reduction in center city parking time
and cost• Drivers safely can do some non-driving activities• Increases in longer auto commuting trips
Impact of Level 4 Technology - Cars
Key Features• Unrestricted self-driving• Empty vehicle movements permittedLikely Impacts• Growth in shared automated taxi services• Non-drivers can make low-cost individual trips• Time spent in motion no longer wasted – in-vehicle
experience is transformed• Vehicle trips may exceed person trips
Could This be the Future of Self-Driving Cars?
The self-driving car as an extension of living or working space
You could live in this.
Impact of Self-Driving Cars on Transit
• Self-driving cars will offer mobility to those transit captives who cannot drive, and, in conjunction with car-sharing, can offer mobility to those who do not have ready access to a car.
• For choice riders, self-driving cars can offer amenities similar to those of
transit in terms of how one can use time while traveling, to read, sleep or work.
• According to studies, automated cars could double highway capacity. Couple that with the ability to self-park, and the transit advantage could melt away.
• So the impact on many transit systems could be huge.
Potential Applications of Autonomous Driving Technology to Bus Transit

Casualty and Liability Claims are a Huge Drain on the Industry
• For the 10 year period 2002-2011, more than $4.1 Billion was spent on casualty and liability claims
• For many self-insured transit agencies these expenses are direct “out-of-pocket”
• Large reserves for claims must be budgeted• Claims experience is reflected in insurance
premiums• There are gaps in data reporting
Costs of Bus Crashes – Industry WideTangible – reported as casualty and liability expense
• Physical damage insurance premiums • Recovery of physical damage losses for public liability and
property damage insurance premiums • Insured and uninsured public liability and property damage
settlement pay outs and recoveries • Other corporate insurance premiums (e.g., fidelity bonds,
business records insurance)
Costs of Bus Crashes – Industry Wide
Tangible -likely not reported as casualty and liability expense
• Accident investigation• D & A testing• Emergency services response• Hearings and discipline• In-house legal services• In-house vehicle repair• Lost fare revenue• Overtime• Passenger and service delays• Sick time• Spare vehicles and replacements• Vehicle recovery
Costs of Bus Crashes – Industry Wide
Intangible• Human loss and suffering• Media attention• Good will
Level 2 Automation - Potential Impact for Transit – Claims Reduction
• Adaptive Cruise Control• Autonomous emergency braking• Blind spot monitoring (for vehicles and
pedestrians)• Driver fatigue and attentiveness monitoring• Lane keeping assistance• Obstacle detection and avoidance• Rear collision warning and mitigation

Opportunities for Autonomous Driving Technology in Transit - Recommendations
• Institutional Response • Technological Response
Recommendation - Transit Institutional Response
• Promote shared-use autonomous cars as a replacement for transit on many bus routes and for service to persons with disabilities
• Exit markets where transit load factors are too low to justify operating a transit vehicle
• Concentrate transit resources in corridors where more
traffic and parking will be too costly and too congested, and where transit can increase the people carrying capacity of a lane beyond that of a general traffic lane
Recommendation - Transit Institutional Response- Continued
• Focus attention on land use – work with partners to create Transit-Oriented Development that limits the need for driving and where trip-end density will provide enough riders
– Create compact activity centers – Allow higher density– Promote mixed use development– Make streets pedestrian and bike friendly– Manage parking ratios and configuration
Recommendations- Transit Technological Response
What we need to do
Prepare for Technological Evolution and Obsolescence
• Buses last from 12 to 18 years or more• Computer technology becomes obsolete in 18
months to two years• Expect to replace components and systems
several times during the life of a bus• Do not expect replacement parts to still be
available • Sometimes stuff does not work as expected
Need Open Architectures and Standards
• Avoid problems of legacy systems and sole
source procurements• Modular systems and components• Standard interfaces between systems and
components• Multiple sources and innovation from vendors• “Plug and play”
Federal Transit Administration Notice of Funding Availability
• Federal Register October 1, 2013• Seeking Research Development Demonstration &
Deployment Projects – 3 Categories– Operational Safety– Resiliency– All Hazards Emergency Response & Recovery
