摘要：AbstractThis paper describes a visual tool for data analysis applied to a case in public transport. Our tool is based on geo-referenced dynamic maps, created with free Web GIS applications, and allows users to visualize data and interact readily with a large database of public transport service information. This tool will support decision-makers in detecting issues of inefficiency and ineffectiveness related to the public transport services of a given area. The paper focuses on the visualization system, its features, and its use, detailing the indicators utilized and the analyses it may be employed for.
