Scenarios tested

• Reference scenario
  Includes PT and road investments as
  defined in the transportation master plan
• 2. Do nothing
  No investments at all
• 3. PT policies
  Increase speed/service by
  5, reduce fare by 20
• 4. Car pricing
  Increase car operating
  cost by 75
• 5. Land use
  PT oriented land use
• Combinations
  34, 345

Conclusions
Car pricing policies are efficient instruments
in fighting urban sprawl
PT policies may contribute to urban sprawl
The combination of the above policies has
positive sustainability effects while
maintaining city sprawl at a reasonable level
The positive effects could be further improved
by supporting the above combination with a land
use policy
14
Conclusion for further research
Introduction of an overall urban sprawl indicator
Introduction of more efficient land use policies
Introduction of a land pricing instrument that
takes into account the external costs of land
development
Approaching the optimum combination of car, PT
and land pricing policies
