  This guideline defines the ITS application sublayer (ITS-ASL: ITS Application Sub-Layer). The ITS-ASL builds and extends ITS platforms for various applications and various wireless communication terminals by expanding the lower layer application scope of the basic application interface (basic API) on narrow area communications (DSRC) defined by the standard ARIB STD-T75 and using this basic API. The ITS-ASL also enables execution of applications using basic API by making it possible to complement the communication protocol functions of other narrow/wide area communications such as ITS FORUM RC-005, IEEE 802.11, IEEE 802.11bd, ETSI EN 302 636, ARIB STD-T109, 4G, and 5G.

 This will make it easier for the existing communications technologies used by ITS and new communications technologies such as V2X technologies to be used in automated driving systems, advanced driving systems, and next-generation satellite billing systems, for which practical implementation and product release are proceeding at a rapid rate both in Japan and overseas.
