PROJECT 1.2 CPS-ATIS PLATFORM SEAMLESS COORDINATION OF CYBER-PHYSICAL INTELLIGENT TRANSPORTATION SYSTEMS MOHAMED ELSHENAWY
OBJECTIVE: A Cyber-Physical Platform capable of: 1. Acquiring real-time urban informatics provided by interconnected sensors, wearable devices, and smart phones (aka internet of thing (IoT)); 2. Transcending acquired informatics into knowledge and awareness of city dynamics; 3. Applying of the acquired situational & contextual knowledge to intelligently deliver city services.
WHAT IS CYBER? Software components (services) such as general-purpose statistics, prediction algorithms, clustering algorithm, etc.
WHAT IS PHYSICAL Sensors and devices generating data at high rates reflecting a detailed status of the city infrastructure
CHALLENGES LACK OF COORDINATION Current ITS solutions are mostly stand-alone systems that are used by a small group of users with little or no support for larger scale collaboration and integration. Incompatible data models, data formats, communication protocols, and implementation technologies limit the interoperability among the composed services and sensors and reduces the end-to-end integrity of the shared information across the different applications. The lack of intelligent and autonomous mechanisms to automatically discover and select IoT sensors and cloud services. The lack of intelligent and autonomous mechanisms to compose and coordinate selected sensors and services
