EMFAC Hong Kong Vehicle Emission Calculation
EMFAC-HK Web Based Training
Example 7: Burden Mode (calculating based on TCM and VKT)
Hong Kong has developed a TCM, which allows medium and heavy goods vehicles to travel
between 10 p.m. and 8 a.m. the next day only. Further, 5% of the VKT occurs at average
speed >0-8 km/hr (Speed Bin#1 in GUI), 25% at 24-32 km/hr (Bin#4), 20% at 48-56 km/hr
(Bin#7), 25% at 56-64 km/hr (Bin#8), and 25% at 64-72 km/hr (Bin#9). Let’s examine what the
emissions are from this change.
