Articles for ITS market Companies attempt new Vehicle-to-Infrastructure communications, including traffic volume measurements and vehicle positioning. -ITS Asia Pacific Forum in Fukuoka-

 ITS Forum was held in Japan for the first time in 22 years. Countries and governments commended the city’s redesign.

The ITS Asia Pacific Forum was held on May 8 - 10, 2018 at Fukuoka International Conference Hall. ITS is an abbreviation for Intelligent Transport System and has an important role in the development of next-generation cars. Regarding the ITS Forum, there are three distinct sectors , International, Europe, and Asia Pacific. ITS related forums will be held in Japan for the first time in 22 years since Tokyo in 1995.
Many research institutes including governments, automobile manufacturers, auto parts manufacturers, IT-related manufacturers and universities in Asia and Oceania participated in exhibitions and lectures at the forum. The main items were many announcements on the automated driving and connected cars. On the technical side MaaS (Mobility as a Service) and the service business.
Also each countries government emphasized redesigning cities that they would support MaaS related policies in the future. Combining buses, trains, trams, bicycles, taxis, ride sharing and walking they aim to eliminate congestion in urban areas and reduce greenhouse gas emissions.

  Utilizing sensor technologies to measure traffic volume and vehicle position are original ideas from ITS in the 1990s.

Japan was an early world leader in this technology.
In the background there are various service projects in which the public and private sectors collaborate.
For example, Japan introduced ETC (automatic toll collection system) utilizing DSRC (Narrow area communication) on highways nationwide. Japan also introduced VICS (Vehicle Information and Communication System) which provides traffic information such as traffic congestion to onboard units, initially in the Tokyo metropolitan area.
In addition Japan is home to the most popular in-vehicle car navigation system in the world and technology competition among companies has further advanced in-car navigation product development. This environment at the ITS Asia Pacific Forum attracted the attention of various sensor technology companies for installation on the road side and efforts to utilize them to measure traffic volume and position of the car.

The following summarizes each company.

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.

I hope that new business models related to ITS will continue to be generated from Japan into the worldwide markets by continuing the various sensing technologies mentioned in the article above.
