REMARKS ON THE EQUIVALENT OF A VEHICLE IN PASSENGER CAR UNITS (P.C.U.)

ASSUMING THAT THE COLLECTION OF VEHICLES IN A GIVEN TRAFFIC SITUATION CAN BE SEPARATED INTO TWO CLASSES OF WHICH ONE CONSISTS OF REFERENCE VEHICLES, THE AUTHOR INTRODUCES THE IDEA OF AN EQUIVALENT, WHICH CAN BE ASSIGNED AS THE FICTITIOUS MEASURE OF TRAFFIC FLOW MEASURED IN UNITS OF REFERENCE VEHICLES. CONDITIONS ARE DESCRIBED WHICH WOULD FACILITATE THE CALCULATION OF AN EQUVALENT IF IT EXISTS. ASSUMING THAT AN EQUIVALENT EXISTS WITH RESPECT TO ONE CHARACTERISTIC OF TRAFFIC FLOW, THE AUTHOR CASTS SOME A PRIORI DOUBT UPON THE POSSIBILITY OF GENERALIZING THIS GIVEN EQUIVALENT TO OTHER CHARACTERISTICS. HE SHOWS CONDITIONS WHICH WOULD PERMIT, OR FORBID, THE EXTENSION OF AN EQUIVALENT FROM ONE CHARACTERISTIC TO ANOTHER. CONSIDERING A TRAFFIC MODEL OF A TWO-LANE ROAD, THE AUTHOR ILLUSTRATES HIS THEORETICAL ANALYSIS BY SHOWING THAT ONE CHARACTERISTIC CANNOT GENERATE AN EQUIVALENT AND THAT TWO CHARACTERISTICS MAY GENERATE TWO EQUIVALENTS WHICH CAN BE NEARLY IDENTICAL OR DISTINCT. /AUTHOR/
