A new hypothesis on traveler behavior in a network is described which is based on empirical findings in the theory of travel budgets. It is translated into an assignment principle for characterizing the distribution of travelers, as well as the demand and mode split. A numerical technique is proposed, and it is applied to several examples to illustrate qualitative features. It is applied to a small network to assess the effect of using vehicle-actuated signal control. It is also applied to a rather large network to investigate traffic control policies and construction policies. Open questions and areas for future research are discussed. The new hypothesis is significant because it considers all travel decisions -- whether or not to travel, where to go, and what mode to use -- in a single, unified way. The feedback from travel time and money costs on links and modes to traveler behavior is explicitly considered.
