The present invention relates to a method of determining physical parameters (Phy) relative to pollutant and/or noise emissions and/or road safety of a vehicle fleet (P1) on a road portion. The method comprises the following steps:a) measuring (MES) the positions (posGPS), speeds (vGPS) and altitudes (altGPS) of vehicles on the road portion so as to determine (DET1) a speed profile (pv),b) determining (DET2) at least one physical characteristic (Tab) on the road portion for each of the fleet vehicles, according to the characteristics (PAR) of these vehicles and to the speed profile (pv) determined in step a),c) applying (APP) the fleet to the physical characteristics determined in the previous step to obtain a distribution (Rep) of the physical characteristics on the fleet,d) determining (DET3) physical parameter (Phy) on the part of the road network portion by means of distribution (Rep) of the physical characteristics obtained in step c).
