Background
Public safety, incident management, risk reduction and access to clear evidence - today’s transit authorities face many challenges. Metro systems are commonly deployed in cities, urban agglomerations and metropolitan areas to transport large numbers of people at high frequency. Some of the busiest metro systems in the world, just to name a few, include New York City Subway, Shanghai Metro, London Underground, Tokyo Subway, Moscow Metro and Seoul Metropolitan Subway. In Taipei, the capital city and the largest metropolitan of Taiwan, with a population of 6.9 million as of January 2012, a well-designed, reliable metro system to transport travellers is crucial.
