World’s First*1 Test of Expressway Traveling of CACC*2 -mounted Trucks in a Caravan with Drivers in the Second and Following Trucks to be Launched Demonstration test of traveling of trucks in a caravan with drivers in the second and following trucks as an effort for achieving the mobility revolution

The Ministry of Economy, Trade and Industry (METI) and the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) have been advancing a project titled “Research and Development/Demonstration Project for Implementation of an Advanced Autonomous Driving System in Society.” As part of this effort, on January 23, 2018, they will launch a demonstration test of expressway traveling of trucks in a caravan in which the second and following trucks are driven by people, taking advantage of a CACC technology. This test will be conducted on part of the Shin Tomei Expressway between Hamamatsu Service Area (SA) and Enshu-morimachi Parking Area (PA).

Under the Future Strategy 2017 (approved by the Cabinet on June 9, 2017), METI and MLIT aim to commercialize expressway traveling of trucks in a caravan with unmanned driving of the second and following trucks in 2022 at the earliest possible time, which is one of the major goals for achieving the mobility revolution in Japan. To achieve this on an expressway, i.e., the Shin Tomei Expressway, in 2020, they have been advancing preparation for launching public-road demonstration tests of traveling of CACC-mounted trucks in a caravan with drivers in the second and following trucks by the end of FY2017 and traveling of trucks in a caravan with a system for unmanned driving of the second and following trucks, in which some drivers ride in the vehicles in case of an emergency.

In 2016, METI and MLIT held discussions concerning issues on inter-vehicle distances required to secure safety during public-road demonstration tests, and prepared a traveling plan in which specific roads and methods are stipulated.

In light of the results of past discussions, METI and MLIT decided to launch, on January 23, 2018, the world’s first expressway demonstration test of trucks, developed by four domestic manufacturers, in a caravan with drivers in the second and following trucks, as part of the project above.

Notes:
*1 This expressway traveling of trucks in a caravan with drivers in the second and following trucks, the trucks of which use a CACC technology jointly developed by multiple truck manufacturers and have been developed by four different truck manufacturers, is the world’s first effort.
*2 The term “CACC” is an abbreviation of “Cooperative Adaptive Cruise Control.” Using a communication means of the cooperative support system for keeping a predetermined inter-vehicle distance, the CACC function receives control information from a leading vehicle, automatically controls speed, and keeps the predetermined inter-vehicle distance.
