A significant part of the computing time requirements of highly disaggregate transport models is due to the large number of iterations required to achieve user-optimal equilibrium in trip assignment. This chapter on iteration-free microassignment is one in a book of essays published in honor of David Boyce for his contributions to the fields of transportation modeling and regional science. In this chapter, the author outlines a methodology to assign individual trips generated in a microscopic activity-based travel forecasting model to a multi-modal transport network without iteration. The rationale of the method rests on the assumption that travelers have only limited information about the current state of the network and that they base their travel decisions on prior knowledge from earlier experience. The author notes that the iteration-free nature of the approach makes it particularly suitable for integrated models of urban land use, transport, and environment (LTE), which are increasingly becoming more disaggregate. The author illustrates the method by a first simulation experiment using the urban region of Dortmund (Germany) as a case study.Read More
