Mobility of passengers and freights in most European capital cities such as Lisbon is not yet sustainable. Road traffic is associated with significant externalities (social, economic and environmental costs) due to daily congestion, traffic noise, air pollution, accessibility problems, and road accidents. In addition, mobility data is dispersed through several entities/operators. The iLU project aims to (i) consolidate the multiplicity of data sources on city mobility stored in the Plataforma de Gestão Inteligente de Lisboa (PGIL) and guarantee its real-time updatability; (ii) discover actionable spatiotemporal patterns of mobility from such heterogeneous data sources, particularly non-trivial correlations between road traffic and situational context data; (iii) anticipate traffic congestion using advanced and integrative predictive models; (iv) real-time support of mobility decisions through the use of deep reinforcement learning to positively condition the city traffic by, for instance, controlling traffic lights and road message panels.
