Análise de indicadores de confiabilidade em uma linha de transporte público

Abstract

The collective public transportation has been gaining more attention as urban chaos and resulting environmental problems become a reality in the lives of the majority of people. The inadequacy of urban planning at the current pace of city growth and the widespread use of individual motorized transport in large urban centers contribute to an increasingly inefficient and unattractive public transportation system. Faced with this scenario of reduced access to quality public transportation and in the availability of November 2018 data from the operation of the public transportation fleet in the city of Fortaleza, an opportunity arose to analyze this system in terms of the reliability of travel times and headway on a major mixed-traffic route. This analysis takes into account the quality issues associated with AVL (Automatic Vehicle Locating), GTFS (General Transit Feed Specification) and Smart Card data sources. The applied method involved preprocessing the data to prepare it for the analysis of travel times based on performance indicators in sections of the "075 – Campus do Pici / Unifor" route in both directions. It also involved the analysis of headway and its distributions at selected stops in each section based on their proximity to areas likely to experience high boarding activity, identified from Open Street Maps data. As a result, sections with good reliability in relation to both analyzed aspects during peak and off-peak periods were identified, such as the "Av. J. Feitosa" section. Additionally, sections that are potentially bottlenecks in the route's operation, such as the "Av. 13 de Maio" section, were identified, revealing opportunities for improvements in route planning.
