PANASONIC

• Vehicle-to-Infrastructure communication at intersection utilizing 60 GHz millimeter wave radar

  In recent years millimeter wave radar has been used as part of ADAS (Advanced Driver Assistance System) for the purpose of irradiating vehicles from the onboard device.
  On the other hand Panasonic is studying a concept model by installing a millimeter wave radar transmitter in the 60 GHz band on the intersection side and measuring the position of the traveling car. The mechanism is used to notify cars at the intersection of that information. According to a company official, because the frequency band is different from the millimeter wave radar for ADAS it does not interfere with millimeter wave radar radiated to the car from the intersection.

• Vehicle-to-Infrastructure communication using the 700 MHz band

  Toyota will deploy the Vehicle-to-Infrastructure communication system using the 700 MHz band around the intersection positioned at the center for diffusion and also to inter-vehicle communication with pedestrian smartphones.

• Reverse running prevention system

  This system utilizes a loop coil type sensor which has already been introduced for measuring traffic volume on the expressway. It will call attention to surrounding cars with an electronic road side display board when reverse running occurs. PANASONIC is now preparing it for introduction.

OKI Electric

A system that measures the position of a moving car using two radio receivers installed on the road side. Radio waves emitted from moving vehicles can use ETC / ETC 2.0, Wi-Fi, etc. They have been developing it for practical applications.

NEXCO West Japan

They have a Compact DSRC system compatible with ETC / ETC 2.0. It is intended for use in the vacation seasons such as New Year's holiday and summer holidays. It has been introduced initially in Kyushu and a part of expressway in Okinawa.

NTT DoCoMo

• Mobile space measurement

  Mobile space measurement is one of the services provided by NTT DoCoMo. Under the user agreement the user’s movements are visualized by obtaining location information of the mobile phone using GPS or Wi-Fi. By analyzing such data using artificial intelligence (AI) they developed a technology to predict human movement. In the future they will utilize it for setting routes such as bus, train, LRT (next generation tram line system) and formulating flight schedules. This service is also able to optimize the placement of temporary buses by predicting the movement of people before and after large scale events such as professional baseball games, soccer games and music concerts.

• AI bus

  AI bus is a DoCoMo project that collaborates with a startup company at the Public Hakodate Mirai University. It is an attempt to get the best match between suppliers and users of small buses using a dedicated algorithm. They have tested and demonstrated at Tokyo and Fukushima. The demonstration in Fukuoka city was arranged as part of this ITS Asia Pacific Forum.
