A Case Study on Visualizing Metropolitan Public Transit on Interactive Tabletops
Smart cities need smart citizens
Urban Demos
LIVE Singapore! Provides people with access to a range of useful real-time information about their city by developing an open platform for the collection, elaboration and distribution of real-time data that reflect urban activity. Giving people visual and tangible access to real-time information about their city enables them to take their decisions more in sync with their environment, with what is actually happening around them.

Three Visualization Modes
• Map View
• Time-Series View
• Arcs View
Switching between these lets users focus on one view, and still enables them to select the best fitting one in order to gain insights based on different data properties.
