19. Sustainable mobility
• We aim for reduced congestion, reduced air
pollution or improved safety by stimulating people
to change their travelling behaviour.
• We investigate how positive incentives can stimulate
smart and sustainable traveling in urban regions.
• 1. Smart phone application senses behavior
• 2. System issues incentives , e.g. travel by bicycle and
get a free coffee
• 3. Smart phone application monitors impact of
incentives.
• 3 Living labs Enschede, Gotenborg and Leeds

20. How
• Locatienet’s focus in the
project is the collection
analysis of measurement
data.
• Application measures and
provides feedback
• Application is ubiquitous,
runs silently in the
background no need to
start / stop
• Measurements are
analyzed on a server

23. Measurement strategy
Smartphone has
many sensors. Some
of them use more
energy than others.
Use them smartly.
GPS & Networking
consume most
energy.
Radio, Accelerometer
and compass are
more efficient

24. Accuracy v.s. Batery usage
User leaves home
100% charge
Normal line = static
Dotted line = travel
Back home 60 %
Phone in charger

25. Basic data = simple
• Timestamp of measurement
• Position (lat / lon)
• Speed (GPS if available)
• Heading (GPS / Compass)
• Quality indicator (measurement error in meters)
• Measurement type
• Battery level
• Data gets a meaning if combined with other data:
− Maps (road network)
− Point of interest
− Other users
