We strongly believe that spatial information
systems can bridge traditional domains
that deal with mobility and foster new and
innovative ways to analyze, plan and
manage our daily mobility demands.

Benefits of being mobile
Is mobility per se benefitial?
No: must serve a purpose
Yes: as recreational activity
What was the purpose of your last trips?

Accessibility
Focus solely on mobility as such of little help
Accessibility as major parameter
Costs and restrictions:
Distance
Time
Monetary costs
Availability of transportation
Physical barriers
Legal barriers
Emotional barriers

The cities will be part of the country; I shall
live 30 miles from my office in one
direction, under a pine tree; my secretary
will live 30 miles away from it too, in the
opposite direction, under another pine
tree. We shall both have our own car.

Multiple Perspectives

Cool, no cars on the
road. I can enjoy a
safe ride!
Stupid pedestrians.
Watch out – the street
is mine!
How beautiful it would
be if this park were
larger. I‘d remove the
parking lots.
A pedestrian zone
would raise the urban
quality enormously.

Synthesis
Mobility is a spatial phenomenom by its very nature
GIS facilitates integrated approach – GIS is everywhere
Analysis
Planning
Operation
GIS addresses ecological, economical and social
implications of mobility
Mobility is a function of space ↔ Mobility shapes space
GIS helps to make these interdependences visible
Spatial analysis for informed decissions
