Abstract

A captive ridership estimation technique seems to be more appropriate to the needs of a city in an underdeveloped economy than the choice ridership estimation techniques used in the technologically advanced countries of Western Europe and North America. Discriminant analysis has been used in this study to estimate the proportion of captive riders in the city of Ile?Ife (estimated population in 1980 was 233,397). Six variables were found to be significant beyond the 0.001 level. These are trips per day by household, annual income of respondent, education, vehicles owned by respondent's household, home?workplace distance and home?workplace travel time. One discriminant function derived for this analysis has been named vehicle ownership dimension based on the relatively high coefficient of the household vehicle variable. This technique correctly classified 81.43% of the total 490 ?grouped? cases, and 50.2% of the trips have been classified as captive ridership.
