A COMPARISON OF U.S. AND EUROPEAN COOPERATIVE SYSTEM ARCHITECTURES

摘要

From the point of view of global producers, ITS products should be uniformly applicable toglobal needs and markets in order to maximize return on investment. Nonetheless, some ITSproduct categories, such as cooperative systems involving roadside infrastructure, must takeinto consideration local conditions, resulting in product variations. In the case of solutionsproposed for intersection collision avoidance, traffic signals, signal timing, communicationstechnologies, road markings, roadside infrastructure and driver behaviors may all differ fromcountry to country. This paper compares the U.S. CICAS-V and the European SAFESPOTprojects, and illustrates how their solutions are similar, where and why they differ, and howinternational standards in communications, message sets and data models are used, resultingin lower deployment costs for all.
