D5 Annex WP 3: DATABASE METHODOLOGY AND DATABASE USER MANUAL – FREIGHT TRANSPORT DEMAND f, g, h and dc are provided as coefficients relevant for calculating cold emissions Evaporative correction E evap, VOC, j = 365. a j (e d + S c + S fi ) + R and: x = v j / (365. l trip ) S c = (lq) (p . x . e s, hot + w . x . e s, warm ) S fi = q . e fi . x R = m j (p . e r, hot + w . e r, warm ) l trip average trip length (km) Examples from e.g. UNITE : corresponding unit costs Examples from RECORDIT: FREIGHT transport including marginal costs 120 Document2 27 may 2004
D5 Annex WP 3: DATABASE METHODOLOGY AND DATABASE USER MANUAL – FREIGHT TRANSPORT DEMAND Variable definition Variable computation method Directly from a database or agreed classifications/nomenclatures Output of the model Method variable V1 Method variable V2 Method variable V3 Method variable V4 Method variable V5 Method variable V6 Method variable V7 Method variable V8 Method variable V9 Method variable V10 Method variable V11 Method variable V12 E total= Total emissions E hot= Hot running emissions e= the hot emission factor (in g/km) m= the activity, in distance travelled per time unit (usually in km/year) n= is the number of vehicles in each category l= is the average distance travelled by the average vehicle of each category over the time unit (in km/year) ec= the corrected hot emission / consumption factor for the vehicle fleet, in consideration of the influence of gradient and in the case of catalyst vehicles of mileage i=the number of vehicle categories v=the road type, practically signifying the mean speed k=the number of pollutants s= the gradient class x= the number of gradient classes Document2 27 May 2004 121
