  1. Emission Factor Development in Thailand Panya Warapetcharayut Director of Automotive Air Pollution Section Air Quality and Noise Management Bureau Pollution Control Department, Ministry of Natural Resources and Environment Bangkok,Thailand

  2. Background and Problems •Number of Motor vehicles •Transportation System - traffic condition - congestion - traffic volume •Automotive air pollution problems

  3. Vehicle Registered in BKK (2003)

  4. Pollution sources portion in Bangkok(PCD,1997)

  5. Automotive Emission Factor (PCD,1997)

  6. Emission Load from Mobile Source (1997)

  7. Objectives • Generate locality fleet data in Bangkok • Develop an air emission database by using MOBILE 6 • Evaluate the mobile source emission inventory data

  8. Scope of the study •Study area is covered Bangkok •Focus on mobile sources •Pollutants concerned: PM,NOx,CO,SOx and HC •prepare computerized database

  9. Air Quality management

  10. Methods and Materials Selection of vehicles HD 20 vehicles LDD 20 vehicles LDG 20 vehicles MC 20 vehicles Dynamometer testing : PCD’s Laboratory Driving Cycle : Bangkok Driving Cycle

  11. Examples of BKK Driving Cycle

  12. HD’s Driving Cycle

  13. LD’s Driving Cycle

  14. PCD’s Emission Laboratory

  15. Modified MOBILE 6 for Bangkok • Vehicle Type • Vehicle use assumption • Ambient temperature • Fuel parameters • I/M Program parameters

  16. MOBILE6 Input 1.Tampering rates 2.VKT mixes 3.Annual mileage accumulation rates 4.Registration distribution by vehicle type and age 5.Basic emission rates 6.I/M program 7.Anti-tampering programs

  17. MOBILE6 Out put The database output will provides: •grams/kilometer output by hour, •pollutants, •emission type, •vehicle class, •vehicle age, •facility type.

  18. QA/QC of MOBILE 6 • Compare emission with overall emissions inventory • Compare emission with per capita emissions • Compare emission with VKT • Compare emission with fleet data and fuel consumption statistics • Remote sensing surveys of exhaust emission • Use of ambient sampling data

  19. Expected Results •support environmental policy •monitor the environmental policy •analyze trends in the emission data •provide the official emission data •disseminate emission data to public

  20. Thank you very much
