Least-Cost Transportation Planning : Eine Konzeptidee : Eine neue Methode zur ökologischen und ökonomisch effizienten Verkehrsplanung

Least-cost transportation planning is meant to permit a cost-oriented evaluation of traffic planning variants. For that purpose, a procedure which was originally introduced in energy business is used as a model. If all relevant traffic service industries (private cars, public transport and cyclists) and traffic offerers (users, traffic businesses, communes) are seen as belonging to one imaginary company, its measures could be evaluated economically. Income and expenditure structures result from communal household plans, annual closings of accounts of traffic businesses and other statistics. In Freiburg, the model city of such an evaluation, 2600 Marks per capita were spent on passenger transport a year: 70 Percent of it were covered by private households, mostly for private cars. For the communes, using the bicycle - with regard to distance - is by far the most economical traffic service.
