Application of mixed-criticality scheduling model to intelligent transportation systems architectures

Intelligent Transportation Systems (ITS) usage has transformed public transports' vision on operation management. However, the lack of common communication interfaces has brought redundancy within on-board applications. In this context, the European Bus System of the Future (EBSF) project has specified a common architecture based on IP standards [1]. It provides a Service Oriented Architecture (SOA) that permits the ITS applications to publish services and subscribe to others. The EBSF architecture enables Vehicle To Infrastructure communications (V2I) through a unique communication gateway, with managing needs of the different data flows depending on their priority in the network and the available communication resources (bandwidth).
