NETWORK AGGREGATION EFFECTS UPON EQUILIBRIUM ASSIGNMENT OUTCOMES: AN EMPIRICAL INVESTIGATION

Three network models were developed for the road network of Eindhoven (population: 200,000): a fine, a medium and a coarse network model. In this article the results of the equilibrium assignments are presented, which are occasionally compared with all-or-nothing outcomes. Mainy load figures are dealt with here. The experiment indeed showed a significant effect of the level of detail on most assignment outcomes. This effect proved to be consistent but diminishing; an increase in the level of detail always yielded better results but only marginal improvement could be obtained beyond a certain level. Compared with all-or-nothing assignment results, equilibrium loads agree much better with the counts at all levels of spatial detail.
