Abstract

The paper examines the theoretical underpinnings involved in rail/road inter?modal split in Tanzania?type economies. Two inter?modal split models geared to the search for an optimal transport mode, i.e. the least?cost mode (Moses, 1958) or a rational combination of least?cost modes (Moses, 1968 and Daughety/Inaba, 1977) are presented. The empirical illustration of the models shows that the ?service?induced costs? are greater determinants of the shipper's market?mode choice than (direct) transport charges. Furthermore it is shown that although the direct costs weigh heavily against road, indirect costs and service characteristics weigh heavily against rail. Thus the optimal choice might in fact be a rational combination of least?cost modes.
