This report summarizes the current state of the art in cooperative vehicle-highway automation systems in Europe and Asia based on a series of meetings, demonstrations, and site visits, combined with the results of literature review. This review covers systems that provide drivers with a range of automation capabilities, from driver assistance to fully automated driving, with an emphasis on cooperative systems that involve active exchanges of information between the vehicles and the roadside and among separate vehicles. The trends in development and deployment of these systems are examined by country, and the similarities and differences relative to the U.S. situation are noted, leading toward recommendations for future U.S. action. The Literature Review on Recent International Activity in Cooperative Vehicle-Highway Automation Systems is published separately as FHWA-HRT-13-025.

This literature review supports the report, Recent International Activity in Cooperative Vehicle-Highway Automation Systems. It reviews the published literature in English dating from 2007 or later about non-U.S.-based work on cooperative vehicle-highway automation systems. This review covers work performed in Europe and Japan, with application to transit buses, heavy trucks, and passenger cars. In addition to fully automated driving of the vehicles (without human intervention), it also covers partial automation systems, which automate subsets of the total driving process. Recent International Activity in Cooperative Vehicle Highway Automation Systems is published separately as FHWA-HRT-12-033.
