Communication Architecture for Land Mobiles (CALM) is a series of Intelligent Transportation System (ITS) communications standards from ISO. These architecture standards form the basis for most of the next generation ITS communication systems. CALM has been adopted by several Asian projects, and have cooperation agreements with IEEE 802.11p. New policy decisions in the United States of America (USA) show a direction towards CALM. European projects have been early adopters of CALM architecture and ideas. The three largest Co-operative system projects CVIS, SAFESPOT and COOPERS all adopt the main ideas and architecture elements. CVIS perform proof-of-concept and validation for CALM. ETSI together with COMeSafety has extended on theoriginal CALM ideas. Several European interoperability tests and demonstrations are planned for 2009 and 2010 based on the extended CALM architecture.
