  Despite the plethora of research devoted to analyzing the impact of
disability on travel behavior, not enough studies have investigated the varying
impact of social and environmental factors on the mode choice of people with
disabilities that restrict their ability to use transportation modes
efficiently. This research gap can be addressed by investigating the factors
influencing the mode choice behavior of people with travel-limiting
disabilities, which can inform the development of accessible and sustainable
transportation systems. Additionally, such studies can provide insights into
the social and economic barriers faced by this population group, which can help
policymakers to promote social inclusion and equity. This study utilized a
Random Parameters Logit model to identify the individual, trip, and
environmental factors that influence mode selection among people with
travel-limiting disabilities. Using the 2017 National Household Travel Survey
data for New York State, which included information on respondents with
travel-limiting disabilities, the analysis focused on a sample of 8,016 people.
In addition, climate data from the National Oceanic and Atmospheric
Administration were integrated as additional explanatory variables in the
modeling process. The results revealed that people with disabilities may be
inclined to travel longer distances walking in the absence of suitable
accommodation facilities for other transportation modes. Furthermore, people
were less inclined to walk during summer and winter, indicating a need to
consider weather conditions as a significant determinant of mode choice.
Moreover, low-income people with disabilities were more likely to rely on
public transport or walking.
