ClockPetals: Interactive Sequential Analysis of Traffic Patterns VAST Challenge MC1 Award: Multi-Challenge Award for Aesthetic Design

Abstract

The visual analytics system ClockPetals aims to reveal the spatiotemporal and sequential patterns of a large traffic record dataset. The system features appealing interactive web graphics that fast illustrate traffic patterns and allow users to locate unusual, anomalous traffic events from multiple demographical and temporal dimensions. ClockPetals also provides the interactive exploration of different vehicle batches via common sequential characteristic clustering. This paper presents the system’s architecture and the benefits of its adoption.
