NEDO is driving a major R&D project to develop traffic management systems for drones. As part of this project, NEDO, NEC, NTT DATA, HITACHI, ZENRIN, Japan Meteorological Association, and JAXA cooperated with Fukushima Prefecture, Minamisoma City, and the Fukushima Innovation Coast Framework Promotion Organization conducted an interconnection test with a drone traffic management system for safer flights by multiple operators in shared airspace, and completed 100 flights per square kilometer per hour. In total, 29 drone operators participated in the test at the Fukushima Robot Test Field (located in Namie, Minamisoma City, Fukushima Prefecture)
Each participant tested interconnection with a drone traffic management system that handled information sharing among multiple drone operators relying on an Integrated Traffic Management function server installed in the operations control center of the Fukushima Robot Test Field, as well as the APIs and API connection support services of the drone traffic management system. In addition to seventeen NEDO Project members, twelve general drone operators participated in this trial. The participation of ordinary drone operators in this test proved the usefulness of the drone traffic management system and the effectiveness of security measures for interconnection.
The National Institute of New Energy and Industrial Technology Development (NEDO) is advancing a major project※1 to develop a drone traffic management system for safe flight of drones by multiple operators in the same airspace and to conduct demonstration tests※2 of a traffic management system at the "Fukushima Robot Test Field※3" (located in Namie-cho, Minamisoma-shi, Fukushima Prefecture). In the future, NEDO aims to enable all operators to operate drones safely and with peace of mind, with an eye toward making proposals to international standards.
In the traffic management system, drone operators can share information on the flight plan of the drone, real-time flight conditions, airspace safety, such as prohibited airspace, with other drone operators by connecting the Traffic Management Function they operate to the Integrated Traffic Management function and Information Provision Function.
Recently, a server was installed in the operations control center of the Fukushima Robot Test Field to provide integrated traffic management functions to enable multiple drone operators to share information. The server went live on August 30, 2019. In addition, rules were developed for the use of APIs※4 for the drone traffic management system. This enabled ordinary drone operators not participating in the NEDO Project to access the server through APIs, and established an interconnection test environment with the drone traffic management system.※5
NEDO, NEC, NTT DATA, Hitachi, Zenrin, Japan Meteorological Association, and JAXA conducted interconnection tests of the drone traffic management system in the Fukushima Robot Test Field in cooperation with Fukushima Prefecture, Minamisoma City, and the Fukushima Innovation Coast Framework Promotion Organization.
In this connection test, seventeen NEDO Project participants and twelve ordinary operators not affiliated with the NEDO Project participated. Looking to the future of wider deployment of drones in the 2020s, testing included airspace densities of 100 flights per square kilometer per hour.
This interconnection test was based on two agreements: Cooperation Agreement※6 on Demonstration of Robot Drones concluded by NEDO and Fukushima Prefecture on November 22, 2017, and the Cooperation Agreement※7 on Human Resources Development for Robots using the Fukushima Robot Test Field concluded by NEDO and Minamisoma City on April 10, 2019.

2. Development and evaluation of integrated traffic management and information provision functions aimed at broader implementation
Within the traffic management system, the Traffic Management Function enables safe drone operations even when multiple operators fly in the same airspace by using information sharing provided by an Integrated Traffic Management Function. In addition, operators can obtain the information necessary to operate drones using map information and weather information provided by the Information Provision Function.
In the October interconnection test, the Integrated Traffic Management Function and the Information Provision Function were connected via a network so that general drone operators not involved in the NEDO Project could participate. To improve the security of the network, firewalls and intrusion detection systems (IDS) were installed, authentication keys were distributed to the providers connecting, permitting only approved operators to connect. In addition, managing flight plans and flight conditions assuming multiple simultaneous drone use cases such as multiple drone weather observation, and multi-drone formation flights for delivery.
The NEDO Project also verified and evaluated the use of airspace and flight rules for the safe operation of these drones through traffic management simulations.
3. Interconnection test with the participation of ordinary drone operators
In this interconnection test, drone operators who were not part of the NEDO Project participated. These ordinary drone operators were as follows. (10 flight test implementation teams, 12 operators, 23 drones)

The NEDO Project supported these ordinary operators to connect to the APIs. The outcomes of flight plan applications and approvals/denials were provided as a Web service, making it possible to submit the area and time of a flight through an Internet browser. In addition, the NEDO Project provided flight control devices onboard the drones to report the position and speed of drones to the traffic management system during flight.
In the future, the NEDO Project plans to improve the user interface so that many more ordinary operators can easily participate in interconnection tests.

By cooperating with the integrated traffic management function and the information provision function, Hitachi, Ltd. demonstrated safe and reliable delivery using multiple drones that assumes the use of a kind of drone highway.
- SUBARU, Nippon Radio Co., Ltd., Nippon Avionics Co., Ltd., Mitsubishi Electric Corporation, and Autonomous Control Systems Laboratories demonstrated that systems equipped with collision-avoidance technologies currently under development under a separate effort with NEDO can interconnect with the drone traffic management system. As a result, the aim was to integrate the UAS traffic management system with collision avoidance technology.
