It is worth exploring in the following illustrations how this new technology might influence the way we live.
Big Data for the Public Good
Seoul and its satellite cities are home to more than 25 million people who are often forced to take expensive taxi rides late at night when buses and subways are no longer available.
When city officials decided to provide a new late-night bus service to commuters, they had to figure out the highest frequency routes and commuter hot spots so they could accommodate as many people as possible.
With the help of Big Data analytics, city officials examined the records of five million late-night taxi rides and 30 billion late-night mobile phone communications, and discovered a sudden increase in rides and text messages at certain places and times.
Based upon this information, they settled on several late-night routes and schedules to provide the bus service to th e maximum number of people.
This was how the Seoul Owl Bus came to be.
