The third phase of transport planning named as modal split is intended to know which modes of
transportation (bus, train etc.) are used by how much fraction of people. Teodorovic and Kalic
(1996) used fuzzy logic to solve the mode choice problem. The authors illustrated the possibilities
of fuzzy logic in solving the mode choice problem using a hypothetical numerical example. The
fuzzy rule base was generated using available numerical data on the differences between the
travel times and travel costs of competitive modes. In other words, learning from examples
generated the fuzzy rule base. The technique proposed by Wang and Mendel (1992a) was used to
generate the fuzzy rule base by learning from examples. There was extremely good agreement
between the results obtained using fuzzy logic and real results.
