摘要：For several years, telematics1) systems based on cellular mobile communications between service centres and on-board units have provided vehicles with basic and value-added subscription services. Millions of road users benefit from these services, generating significant economies of scale. Over recent years, cooperative intelligent transport systems (ITS) have advanced beyond the scope of telematics services. And in recent trials, many safety, mobility and environmental applications, enabled by connectivity among vehicles, infrastructure, and wireless consumer devices, have gained momentum.
