DISTANCES BETWEEN LINES AND STATIONS IN URBAN PUBLIC TRANSPORT SYSTEMS

LINIEN- UND STATIONSABSTAENDE IN OEFFENTLICHEN STAEDTISCHEN VERKEHRSNETZEN

THE PAPER CONTAINS STATEMENTS ON THE RELATION BETWEEN THE DENSITY OF PUBLIC TRANSPORT NETWORKS AND THAT OF ITS STOPPING PLACES. THE RELATIONS ARE DERIVED FOR IDEALISED NETWORK MODELS (HOMOGENEOUS AND SUPERIMPOSED ORTHOGONAL GRID), IN WHICH TWO CRITERIA NEED TO BE APPLIED - THE MINIMISATION OF TRAVEL TIME AND OF VIRTUAL TRAVEL COSTS. VIRTUAL TRAVEL COSTS HAVE TO BE UNDERSTOOD AS ONE OUT OF SEVERAL OBJECTIVES RESULTING FROM SUPERIMPOSED TARGET VALUES, IN WHICH TIME AND COST FACTORS ARE VARIOUSLY WEIGHTED. FOR THE WEIGHTING, THEORETICAL OR BENEFIT VALUE ASSESSMENTS ARE APPLIED. BECAUSE OF THE IDEALISED ASSUMPTIONS AND THE MULTIPLICITY OF VARYING PARAMETERS DURING THE PREPARATION OF THE MODEL, NO UNIVERSALLY VALID VALUES FOR OPTIMUM DENSITIES CAN BE PROVIDED, BUT NEVERTHELESS AN ECONOMIC RANGE CAN BE DEFINED. IT SHOWS THAT THE CHOICE OF INTERVALS BETWEEN STOPPING PLACES AS WELL AS THE DENSITY OF THE NETWORK IS IMPORTANT TO THE SUCCESS OF THE TRANSPORT SYSTEM. THE LESS THE DENSITY OF THE NETWORK, THE SHORTER SHOULD BE THE DISTANCE BETWEEN STOPS. THIS HAS THE CONSEQUENCE THAT IN THE PLANNING OF RAPID OR UNDERGROUND SYSTEMS CONSIDERATION MUST BE GIVEN TO THE SECONDARY FEEDER ROUTES. FEEDER ROUTES ONLY MAKE SENSE WHEN THE PRIMARY NETWORK REACHES AN ADEQUATELY HIGH DENSITY.
