The document discusses the BigDataEurope project and its 7 societal pilot projects that demonstrate the value of big data technologies across different domains. The pilots implement workflows using the Big Data Integrator platform across challenges in transport, security, health, agriculture, energy, climate and social sciences. A transport pilot is presented in detail, showing how it uses open source tools like Kafka, Flink and Elasticsearch to enable real-time traffic condition estimation. Finally, the security pilot is demonstrated.
