ESTIMATING ORIGIN-DESTINATION FLOWS BY SIMULATING TRIP CHOICE

For many traffic studies it is necessary to know the numbers of trips from origins to destinations, but it is difficult and expensive to measure such data. This paper describes a new method which is being developed to estimate o-d trip tables from counts of average traffic flows. The method, called modcost, is based on a simulation of the choices made by several thousand individuals whose different perceptions of the costs of options is represented by a randomisation procedure. The accuracy of the method is assessed using a data-set from a medium-sized town and comparisons are made with other methods of estimating o-d trip tables. (Author/TRRL)
