Accident precursors and safety nets: leading indicators of tanker operations safety

Leading indicators, one type of accident precursor, are conditions, events or measures that precede an undesirable event and that have some value in predicting the arrival of the event, whether it is an accident, incident, near miss, or undesirable safety state. Leading indicators are associated with proactive activities that identify hazards and assess, eliminate, minimize and control risk. An empirical analysis of leading indicators of safety for an international energy transportation company was undertaken, utilizing a previously validated research model. Quantitative safety performance and qualitative safety culture data were obtained from 943 participants on 37 vessels from three fleets in the organization. Organizational, vessel and individual safety factors and leading indicators were identified and an analysis of fleet, vessel, and individual safety cultures was undertaken. The results indicate that individual and vessel-level leading indicators can provide important input to an organization's continuous safety measuring and monitoring systems.     

Multi‐criteria analysis procedure for sustainable mobility evaluation in urban areas

This paper proposes a procedure to evaluate sustainable mobility in urban areas. A set of indicators according to three dimensions of sustainability, i.e., environment, economics, and social aspects, are proposed to evaluate mobility in urban areas. The sustainable mobility evaluation is based on an Index calculated through a weighted multi‐criteria combination procedure. A group of specialists in Brazil was involved in the development of the Index by defining the weights for the criteria. An application of the methodology in the city of Belo Horizonte, capital of the State of Minas Gerais, with 2.24 million inhabitants, is presented to validate the methodology.
