SETA is heavily based on real world requirements and data. Therefore, it has implemented use cases in three different cities: Birmingham, UK; Turin, Italy and Santander, Spain. All three metropolitan areas are complementary as they provide different social and technical challenges, as well as different mobility objectives. They all are regarded as extreme congestion locations, with two of them ranked within the most extreme of congestion locations across all of the EU cities. They will therefore enable the definition of very comprehensive requirements as well as validation in very different situations.
