This study presents measurements of the overall level of service (LOS) for people with disabilities (PWDs) at public bus terminals. According to user perceptions, these metrics are helpful for evaluating the total LOS on a single scale. The process entails watching passengers and gathering a number of socioeconomic and physical factors that could affect how users rate the bus terminal. With the ability to assess and determine the LOS of transit terminals for physically challenged people, solutions to develop more empathetic transit terminals can be identified, and efforts to confirm the deficiencies can be put into place. It is possible to derive quantitative LOS ratings from survey data using a psychometric scaling technique. Following that, the relationship maps between these two categories of items were examined. The quantitative LOS ratings indices were rated using survey analysis. The findings revealed that the grand mean for expected service was 3.67 (SD = 0.77) while the mean for recorded LOS was 2.01 (SD = 0.58), indicating a significant gap between the two, thus needed attention to address LOS given to PWDs. A planning guideline for IPA is offered to design and optimise bus terminal access facilities for new or existing terminal stations, underscoring the practical usefulness of the approach. The outcome from this study evidently if incorporated in designing Bus Park will help in modelling bus terminal that will accommodate PWDs.
