With the collection of excessive amounts of movement data, the analysis of routes has become very important in the exploration of these datasets. To reveal the hidden information in the data, many visualization approaches are proposed according to analysis type. The analysis in this thesis involves visualization of route deviations which occur due to several reasons such as traffic congestion, accidents, weather conditions, or operational issues. The proposed system integrates two visualization techniques for multiple routes visualization: circle-glyph representation and route coloring. While route coloring emphasizes deviations on general trends, circle-glyph visualization concentrates on the detailed analysis of deviations. Level of detail is applied in some visualization parts. A usability study with statistical analysis of its results is performed to evaluate the success of the proposed approaches.
