Abstract
The journey to work had been the subject of
several studies. Results from dome of these studies
have been used to formulate models for use in travel
demand forecasts. However, virtually all these
studies have been carried out in the developed countries.
Because of differences in environmental factors,
one cannot arbitrarily adapt their findings
for use in developing countries like Nigeria. Hence,
it is necessary for similar studies to be carried out
in Nigeria, so as to evaluate the prospects of transfering
results and also to determine the limitations
of the study techniques as regards their applicability
to local conditions.
This work examines the commuting patterns of some
randomly selected Civil Servants working in Kaduna
State Government Secretariate.
The questionaire methods of data collection was
utilized in gathering information on the travel behaviour
of the selected subjects. Questions asked cover
both level of service attributes of the modes used
and socio-economic characteristics of the respondents.
Discriminant analysis was then used to isolate the
major factors responsible for differences in mode
choice.
Prior to administering the questionaires, the
distrubution by income of the total population of
Civil Servants, from which samples were taken, was
obtained. Proportionate numbers of worker were then
randomly chosen within each income group. However,
disproportionately small response rate was obtained
from the low income groups. This suggests that special
attention has to be paid to low income earners
when conducting such studies, with the use of questionaires,
in order to have a fair representation of
the lower income group. Personal income was found
to be a great determinar t of the mode selection of
the studied workers. It was also found that transport
fare weighs heavily in the mode choice decisions
of the workers. This letter findings would seem to
be at variance to the general belief that travellers,
in developing countries, are mode-captive. However,
no other level of service attribute was found to be
statistically significant from the discriminant analysis.
The results sugges that when questionaires are
used for data collection in developing countries,
special attention need be paid to the low income
earners. This would yield a more proportionately uniform
data representation across the income groups.
The results also suggest that variables like travel
times do not contribute significantly to the modechoice
decisions, in contrast to findings in similar
studies in developer countries. These findings indicate
that methods of model development derived in
developed countries are not generally transferable to
the developing countries.
