NTT DATA Automobiligence Research Center, Ltd.

　On June 18,2021, NTT DATA Automobiligence Research Center, Ltd.(abbreviation:ARC) released "GARDEN ScenarioPlatform". This is open source software developed through the GARDEN project, which aims to promote the development of various software functions for next-generation mobility. this works as a platform for scenariobased validating autonomous driving systems.
　　ARC hopes that this free and refurbish able open source will be utilized widely in the automotive industry. As a result, it would be grateful to promote the development of autonomous driving ststems.

Background and Purpose

　Today, when the automobile industry and transportation society have entered the CASE era, automotive industry companies are energetically pursuing research and development toward the realization of autonomous driving. Ensuring the safety of this system has become a major issue. Safety validation is also becoming more important in the software development process that forms the basis of autonomous driving systems.
　ARC is an R&D center in ＮＴＴ ＤＡＴＡ's automotive software business. ARC believes that using scenario-based processes in the development of autonomous driving software by OEM and suppliers is an important solution for achieving sufficient and efficient safety validation.ARC has decided to release this scenario-based validation platform software as an OSS that incorporates some of the results of the R&D project "GARDEN", for free.

Function overview of GARDEN ScenarioPlatform

　GARDEN ScenarioPlatform supports the scenario-based validation process in autonomous driving software development and generates executable scenarios in the functional operation simulation of autonomous driving systems.
　This OSS user will be able to analize the driving data obtained from FOT etc., extract the scenario, and specify the parameter range from the statistical processing. When building a validation scenario obtained from expertise, it is possible to gradually grow from ahighly abstract scerario description to a concrete scenario that can be simulated.
　CARLA is used in the simulation.It is possible to connect to Autoware and Simulink.There is also an interface that can link with existing simulators that support the international standard formats OpenSCENARIO and OpenDRIVE in scenario-based development.
