Intelligent transportation systems (ITS) have the potential to transform road transportation and personal mobility. Advances in information and communication technologies are leading to the emergence of intelligent vehicles (IVs) that involve many challenges from vehicle design to control, coordination, decision-making and human interactions. Using a combination of Engineering and Statistics, scientists of the EU-funded BITS project will work on a novel methodology for uncertainty identification and efficient estimation of various unknown parameters of ITS. They will conduct physical tests to validate the proposed methodologies. This work will provide an accurate representation of a network of IVs and will contribute towards the deployment of IVs in real traffic networks.<\/strong><\/p>\n

        • Posterior distributions are derived for the unknown parameters and quantities of interest, which are the required representation of uncertainty, and are used to make predictions of the system through the posterior predictive distributions.<\/li>\n
        • Bayesian nonparametric methods are able to modify the model\u2019s complexity based on the complexity of the data.<\/li>\n<\/ul>\n

          This project will provide an accurate representation of a network of IVs along with the probabilistic uncertainty concerning the vehicles, to gain insights on their performance, reliability and safety and improve the predictability of the system. As part of the project, physical tests will be conducted to validate the proposed methodologies and with the use of computer science tools will evaluate and minimise risks in the dynamic environment of IVs.<\/p>\n

          BITS is highly interdisciplinary and combines methods from Engineering, Statistics and Computer Science. It will bring together the best practices and state-of-the-art methods of different fields and support the Fellow, who has a strong background in Bayesian learning, to make significant contributions via collaboration with the supervisors, who are experts in ITS, and with leading groups in the field.\u00a0<\/p>\n
