ABSTRACT
The origin-destination matrix is an useful tool for traffic and transport analysis. This kind of matrices are increasing in volume and complexity due to the availability of new technologies to gather new information. In this project we present a novel way of representing origin-destination matrices using a connection barchart and two coordinated maps. The main goal is to use the connection Barchart as the center of the interactive visualization providing an overview of the dataset. Through interaction, the information about specific origin-destination nodes in the origin-destination matrix is shown in both the connection barchart and the coordinated maps, giving the user information about origin, destination, direction, and volume of flow. Additionally, an evaluation with users was conducted to test the usefulness and usability of the interactive visualization using real data for the RBT system in Bogota, Colombia.
