Kinds
of
Problem
in
Urban
Systems
1. Broken
hydrants:
visible,
large
faults
Fukushima,
BP
oil
spill
2. Leaky
faucets:
a

of
waste

7. Main
elements
of
approach
• Random
rewards
and
redemp>on
games
‒ Small
determinis>c
rewards
don’t
incen>vize
change,
we
use
a
raffle-‐like
system
‒ Games
of
chance
are
essen>ally
“self-‐administered”
raffles:
intui>ve,
fun
and
engaging
• Social
nudging
‒ Is
powerful:
friends
significantly
affect
behavior
shiW
• Personalized
recommenda>ons
‒ Incen>vize
customer
segments
depending
on
impact
on
conges>on
and
propensity
for
shiWing
• Detailed
analy>cs
‒ Commuter
behavior
is
analyzed
along
temporal,
spa>al
and
behavioral
axes
• Smartphone
apps
‒ Act
as
sensor;
give
real-‐>me

recommenda>ons
to
users
