Machine Learning on Track with Rail Trials

Boasting one of the most advanced rail networks in the world, Japan is investigating the use of artificial intelligence and a machine learning technology approach that would attempt to add what promoters call a "train time delay" function intended to provide riders with up-to-date route-planning information. Fujitsu Ltd. (TYO: 6702) said this week it has begun field trials in Japan for a delay time prediction engine developed with partner SRI International of Menlo Park, Calif. The trial also leverages a route-planning app developed by partner Jorudan Co. that claims about 10 million monthly users. The partners said the time delay engine learns from past train delay information. Updates on train delays are delivered as a cloud service.
