Such procedures are based on utility maximization where the utility depends on person and route characteristics (trip duration, route length, number of left turns

etc). In this paper it is proposed to integrate an additional (to the ones currently used) route feature in the choice process. In this paper it is proposed to integrate in the choice process an additional route feature (to extend the currently used set). The additional feature is the minimum number of intermediate destinations that is required to reconstruct the path from least cost components. The idea is that the traveler might have mentally constructed the path as a sequence of such intermediates (which can be landmarks) and then tries to reach each one of them as efficiently as possible.
