Abstract
This study assesses the determinants of urban household road travel demand and
transport mode choice. A negative binomial and ordinary least squares regression, and the alternative specific conditional logit model are estimated using survey data.
Results consistently show that daily demand for travel is inversely related to the cost
of travel and positively related to average monthly income. Trip volumes increase
with household size, age, and education level of the household head, but decreases
with car ownership and private sector employment as compared to public sector
employment. Distance travelled falls with household size, age and education level
but increases with car ownership. An increase in travel time by using a given
transport mode reduces the probability of using that mode while the chances of
choosing other modes increases. Relative to the chances of choosing a taxi (14-seater
minibus), an increase in travel cost and income increases the chances of using a
private car or boda-boda (motorcycle); the probability of choosing a private car or
boda-boda is inversely related to trip length and average daily trip volume; rich
households as compared to the poor and larger households prefer a private car
instead of boda-boda; those with older heads prefer less of boda-boda and private
car; unlike female headed households, male headed ones are more likely to choose
boda-boda instead of a private car. A combination of solutions is required for
sustainable travel demand and traffic management: provision of an efficient public
transit system coupled with increased private car parking costs, promotion of car- pooling; road tolls for drive-alone private cars; limiting access times and
