About TrueMotion
3. Driving is one of the most
dangerous things people do daily
4. We use signal processing and
machine learning to characterize
driver behavior and accident risk
● How much you drive: annual mileage
● When and where you drive: city vs. highway,
road conditions, time of day
● How you behave behind the wheel: speeding,
acceleration, braking, cornering, and especially
distracted driving habits
5. Distracted driving dramatically
elevates your risk of an accident
Drivers who admit to texting while driving1
36%
Drivers who actually text while driving2
70%
Increase in baseline driving risk due to
texting while driving36x
1. State Farm Distracted Driving Survey 2015
2. TrueMotion 2015 field test of 360 drivers / 17,000 trips

9. Behavioral economics
● Why do people make
irrational / sub-optimal
decisions?
● Biases: information we
use to make decisions is
often not representative
● Heuristics: we often
approximate hard
decisions with simpler
ones
10. Biases and heuristics
Optimistic bias / overconfidence
● We often think we have more control over events than we
really do (“illusion of control”)
● Thinking we have too much control while driving can lead us
to make poor decisions while behind the wheel
Availability heuristic
● We estimate true probabilities using the frequencies of our
real-world experiences
● By driving without getting into an accident, we believe driving
is less risky than it actually is
11. TrueMotion’s goal: to get people to
think differently about the risks of
distracted driving
12. Data visualization helps counteract
our cognitive biases by allowing us to
explore complex causes and effects
13. Data visualization can help us to...
● Show drivers how individual choices aggregate
into long-term behavior
● Help drivers understand how their actions
affect their risk of an accident
● Illustrate how changes in risk equate to
real-world consequences

19. TrueMotion GradeMyDrive
● Visualization project with Matt Beaulieu (WPI)
● Combines predictive risk modeling with accident
data to help people understand the impact of their
driving behaviors
● Allows drivers to experiment with behavior to
understand how choices can change outcomes

23. Ongoing work
● Real-time feedback of driving risk (based on
behavior, traffic, road conditions)
● Modeling and visualization of risk habits:
understanding when, where, and why you take
your biggest risks
● Relative risk: modeling and visualizing how your
choices and risk compare to drivers like you
