摘要

The Swiss federal government has asked the IVT, ETH Zuerich in collaboration with the TU Dresden and Emch + Berger, rnZuerich to estimate origin-destination matrices by mode and purpose for the year 2000. The complex zoning system employing about 3000 zones required an algorithm which is fast, but also able to face generation, distribution and mode choice simultaneously.rnThe EVA algorithm developed by Lohse et al. [Lohse, D., Teichert, H., Dugge, B., Bachner, G., 1997. Ermittlung von Verkehrsstroemen mit n-linearen Gleichungssystemen unter Beachtung von Nebenbedingungen einschliesslich Parameterschaetzung rn(Verkehrsnachfragemodellierung: Erzeugung, Verteilung, Aufteilung). Schriftenreihe des Instituts fuer Verkehrsplanung rnund Strassenverkehr, H. 5/1997, Fakultaet Verkehrswissenschaften "Friedrich List", Technische Uniyersitaet Dresden] was adapted for this purpose. The key properties of the algorithm are a disaggregate description of the demand, and its use of appropriate logit-type models for the demand distribution, while maintaining the known marginal distributions of the matrices generated. The algorithm calculates trip production and attractions by zone using activity pairs. The combined destination and mode choice models are estimated for the different traveller types and activity pairs.rnThe paper derives and describes for the first time the EVA algorithm in English, including the solution method used. Second, it summarises the results of choice model estimation providing generalised cost elasticities of demand by purpose and traveller type. Third, it discusses the quality of the results by assessing the structure of the matrix against actual census data for road and rail traffic.
