Individualized Traffic Data enables
combining of traffic data
and associated DBs.
Examples
Combining Socio-economic activities
with traffic data
SEGi : Socio Economic Geographical Index
It divides the area into several blocks and provides
the statistics for each block.
Socioeconomic
activities of
people can be
converted to
SEGi data and
then combined
with existing
traffic data.
Individualized traffic data can be linked to the associated
databases.

Conclusion
Existing traffic data shows just the phenomenon of movement.
WHAT Passenger, Freight
HOW Car, Bus, Truck,
Flight, Boat, etc.
WHEN Departure & Arri-
val time, etc.
WHERE Origin & Destina-
tion, etc.
WHO ?
WHY ?
We could know WHO and WHY in mobility
