Avaliando a efetividade da Internet das Coisas aplicada ao sistema de transporte público: um estudo de usabilidade do aplicativo "Cadê Meu Ônibus?"

Abstract

This study analyzes the effectiveness of the Internet of Things (IoT) applied to the public transport service in the city of Manaus, Amazonas, identifying the usability factors that most contribute to the perception of improvement in the user experience. The analysis focused on users of the “Cadê Meu Ônibus?” app through a quantitative and descriptive survey, with data collected via questionnaire to capture aspects of usability, effectiveness and demographic characteristics of the sample. The analytical process included a description of the respondents' profile, correlation between usability and effectiveness variables, and non-parametric tests to assess differences between profiles. The results show that users consider the application to be easy to use and a means of reducing uncertainties when organizing their trips, but point to reliability as a critical aspect. The data from the correlation analysis showed that the perception of a reduction in the uncertainties associated with public transport, provided by IoT technology, and the ability to plan journeys are the main factors that contribute to improving the experience of users of the “Cadê Meu Ônibus?” app. Reliability and ease of use showed the least influence in the analysis, as they are fundamental characteristics and already expected by individuals looking for technologies similar to the one analyzed.
