Development of On board Passenger Information Display
Kiaki Matsumoto Koji Nakada Kazuya Azuma Hiroshi Hatakeyama Tatsuya Tokunaga Kazunori Takahashi OVERVIEW: Advances in ICT and display panels in recent years have led to on board passenger information displays becoming commonplace on commuter trains. Hitachi commenced serious development in 2006 with the development of an on board passenger information display based on the concept of experience design from a user's perspective and achieving a high level of equipment utilization by adopting the autonomous decentralized architecture that was already being used for our traffic management systems. This involved performing information design (visibility and intelligibility) for the passenger information display to suit the diverse variety of people who ride on commuter trains. Hitachi adopted open system interfaces and software to implement the functions of a total system (including both onboard and wayside systems) that would be able to grow over time without becoming obsolete.
