  1. SCATTERSPRAWLING CITIES AND TRANSPORT:FROM EVALUATION TO RECOMMENDATIONS SCATTER WORKSHOP MILAN, OCTOBER 24th, 2003 Kari Lautso: Testing selected solutions to control urban sprawl -Case Helsinki

  2. Policy selection

  3. 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: 3+4, 3+4+5

  4. The model area The Helsinki model external zoning system The Helsinki Metropolitan area zoning system

  5. Projects included in the reference solution

  6. Example of impacts:Noise Level Differences

  7. Land use changes in the Do - nothing - scenario Housing Employment

  8. Land use changes in the car pricing policy (+75%) Housing Employment

  9. Land use changes in the PT policy Housing Employment

  10. Land use changes in the combined PT and car pricing policy Housing Employment

  11. Urban sprawl assessment

  12. Sustainability evaluation Environmental Social Economic

  13. 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
