13. SCATTER WORKSHOP 24.10.2003KARI LAUTSO / LT CONSULTANTS 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. SCATTER WORKSHOP 24.10.2003KARI LAUTSO / LT CONSULTANTS 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
