This paper presents a comparison of U.S. and European Cooperative System Architectures in the arena of intelligent transportation service (ITS) products. The authors maintain that, from the point of view of global producers, ITS products should be uniformly applicable to global needs and markets in order to maximize return on investment. Nonetheless, some ITS product categories, such as cooperative systems involving roadside infrastructure, must take into consideration local conditions, resulting in product variations. In the case of solutions proposed for intersection collision avoidance, traffic signals, signal timing, communications technologies, road markings, roadside infrastructure and driver behaviors may all differ from country to country. This paper compares the U.S. CICAS-V and the European SAFESPOT projects, and illustrates how their solutions are similar, where and why they differ, and how international standards in communications, message sets and data models are used, resulting in lower deployment costs for all. The authors conclude that there is a need to have international standards to work with a variety of infrastructure solutions for communications, message sets including spatial data, and semantics in general.
