This Technical Report surveys the status of Local Dynamic Map (LDM) regarding architecture, implementation, and standardization efforts. It summarizes the high level architectures of the most important implementations and compares it with the CEN/ETSI/ISO ITS-Station architecture.

This Technical Report derives out of the application needs the requirements for a global LDM concept in terms of functionality, technical and legal aspects.

A gap analysis with existing specification and standards will be performed and recommendations towards SDOs and decision bodies will be made.

This Technical Report does not give any decision on how or whether one of the solutions described is commercially feasible to be considered as an implementable offer to the user.

This Technical Report considers the most important documents and research projects to the knowledge of the authors, but does not claim to be complete or free of any mistakes.
