PUBLIC URBAN TRANSPORT SYSTEM "METRO CONTINUA"

SISTEMA DI TRASPORTO PUBBLICO URBANO "METRO CONTINUA"

A TRANSPORT SYSTEM IS CHARACTERIZED AND MADE VALUABLE BY THE MAXIMUM QUANTITY OF PASSENGERS THAT IT CAN MOVE IN A GIVEN PERIOD OF TIME. FOR THIS VALUE THE FLOW THROUGH ANY GIVEN SECTION OF LINE, EXPRESSED IN PASSANGERS PER HOUR, IS GENERALLY CONSIDERED. THE CONDITIONS FOR WHICH A TRANSPORT SYSTEM CAN BE DEFINED AS CONTINOUS, CAN BE MORE EASILY ANALYSED BY EVIDENCING THAT THE VALUE OF THE FLOW IS STRICTLY CONNECTED TO THREE FUNDAMENTAL PARAMETERS: THE NUMBER OF PASSENGERS CARRIED BY THE VEHICLE, THE INTERVAL BETWEEN VEHICLES,THE SPEED OF THE VEHICLE. CONSEQUENTLY, FLOW CAN BE CONSIDERED AS THE PRODUCT OF A MASS DENSITY (WHERE THE CONSIDERED MASS IS ONLY THE PAYLOAD) AND A SPEED, IN OTHER WORDS DIMENSIONALLY IT IS THE EXPRESSION OF "TRANSPORT MOMENTUM". THE "DIMENSIONING" OF A TRANSPORT SYSTEM IS TIED TO A VALUE WHICH CAN ALSO BE DEFINIED AS THE "DESIGN FLOW". THEREFORE, IN A CONTINOUS SYSTEM, THE CONVENTIONALLY INDICATED "MAXIMUM PEAK" COINCIDES WITH THE MAXIMUM TRANSPORT MOMENTUM, IN OTHER WORDS THE DESIGN FLOW. IN A DISCONTINOUS SYSTEM INSTEAD THE "MAXIMUM PEAK" IS INDICATIVE OF A MEAN VALUE OF TRANSPORT MOMENTUM. WHEREAS THE DESIGN FLOW REACHES VALUES WHICH ARE EVEN MUCH GRATER THAN THAT WHICH PRACTICALLY CHARACTERIZES THE SAME TRANSPORT SYSTEM.
