NEVES, Diego Vieira. Use of supervised learning to analyze reliability of crowdsourcing bus location data. 2018. 87 p. Dissertation (Master of Science) – School of Arts, Sciences and Humanities, University of São Paulo, São Paulo, 2018. Researchers from different areas are studying the development of what we call Smart Cities: integrating Information and Communication Systems with Internet of Things to use city resources more intelligently. A major objective of smart cities is to solve problems related to urban mobility that significantly affects the quality of life of the population. An observable problem in big cities is the quality of their public transport services, specifically when we refer to the bus modal. The lack of reliable information, associated with the poor quality of public transport services, encouraging the user to look for alternatives, which aggravates urban social and environmental problems. To reverse this scenario, smart cities initiatives propose the use Intelligent Transport Systems, that can use various sensors and equipment to collect several types of data on public transport services. The capture and processing of these data allows, in theory, citizens to use the public transport with reliability and predictability. However, this data can be insufficient or of poor quality for usage in real-time. This master’s work investigates the use of crowdsourcing data as a complement to this information. To mitigate the uncertainties introduced by the use of crowdsourcing, this research proposes and compares the use of different machine learning techniques to create a reliability analysis model for the data collected that is specialized for use on public transport system (bus) in the city of São Paulo. The results show that the Decision Tree and Gaussian Naive Bayes algorithms are more effective and efficient in performing the classification activity of the data obtained with crowdsourcing. The Decision Tree algorithm presented the best performance indicators in terms of accuracy (94.34%) and F-score (99%), and the second best execution time (0.023074 seconds). The Gaussian Naive Bayes algorithm was the most efficient, with an average execution time of 0.003182 seconds and was the forth best result in terms of accuracy (98.18%) and F-score (97%).
