The high degree of reliance on motorcycles for daily commuting in low-income communities of the Special
Region of Yogyakarta has emerged as a pressing transportation issue, stemming from economic disparities that
have led many low-income individuals to experience transport or mobility poverty, further constricting their
overall mobility. This reliance on motorcycles as the predominant mode of transport demands attention, as it
conflicts with the principles of sustainable mobility. The present study collected survey data from 430 respondents
in
order
to
explore
this
phenomenon.
The
study
then
examined
socioeconomic
conditions,
mobility

patterns,
and
behavioral
factors
among
the
respondents
using
the
theory
of
planned
behavior
(TPB)
framework,

with
the
structural
equation
model
(SEM)
serving
as
the
analytical
tool.
The
findings
of
the
study
reveal
that
cost

savings,

time efficiency, and societal factors exert a significant influence on the high reliance of low-income
communities on motorcycle use. These findings underscore the practicality and affordability of motorcycles,
which, in the absence of viable alternatives, become the primary mode of daily commuting.
