The NOESIS Decision Support Tool is using machine learning techniques to predict the potential value of Big Data investments in Transport. The prediction algorithms are based on a sample of over 100 Big Data in Transport use cases that the NOESIS consortium analysed. To use the Tool you input information on "Transport mode", "Transport sector", "Type of data", "Sample size", "Operational costs", "Investment costs", "Transport challenges", and you get as output the potential value of your investement. The Tool can be used for pre-screening when considering Big Data in Transport investments and solutions.
