where:
Kind,pis the interpolation coefficient for the considered individual vehicle for period p;
E1,pis the energy demand for the considered period for vehicle L in accordance with paragraph 5. of Sub-Annex 7, Ws;
E2,pis the energy demand for the considered period for vehicle H in accordance with paragraph 5. of Sub-Annex 7, Ws;
3,pis the energy demand for the considered period for the individual vehicle in accordance with paragraph 5. of Sub-Annex 7, Ws;
