As for ITS technology, Clarion has developed two original technologies as a result of our work in developing the SS wireless communication system. One is the Automatic Dependent Surveillance System that allows centralized management at the control tower, of vehicles operating in a vast area, through a wireless data link. Clarion participated in a development project to create a system primarily intended for vehicle surveillance at an airport. Currently the system is installed and operating at various sites including Shin-Chitose Airport and Chubu International Airport in Japan. The other development is a dispersed type control system, namely our wireless Intervehicle Communication System for IMTS (Intelligent Multimode Transit System). IMTS enables automated linear running of multiple vehicles through the high-speed communication of information such as vehicle speed and position data using transceivers installed on each vehicle. An amusement park in Awajishima uses this technology to effectively control shuttle bus services within the park.

* Spread Spectrum (SS) wireless communication spreads data over a spectrum and transmits it over a wide frequency range.
