Samenvatting
A model for travel choice relations has been developed, which utilizes as independent variable a composite of the more traditional factors in traffic analysis The marginal disutility of given means of transport was the differential disutility. The final decision variable combined out of pocket cost of public transport and motorway travel, income, parking cost as well as time. The application of the mode choice utility function to the cities St. Paul-Minneapolis is described. The results reproduced base year (1958)transit travel patters well, without the use of curve fitting procedures. The behaviouristic approach used may surpass constraints of public transport service levels, as hitherto applied. It appears to be universally applicable
