Intelligent transportation systems (ITS) integrate information and communication technologies (ICT). They play a crucial role in modernizing urban infrastructure and promoting sustainable mobility to ilmprove the efficiency, safety and sustainability of transport networks. The component and systems suppliers have to promote the integration of their product offer in the value chain (drivers, cyclists, pedestrians, repair or maintenance operators, sellers, etc.) as well as in the full range of mobility connected devices (cars, cycles, tools, rads, etc.), based on digitalization and open data. This will allow to give a better understanding of mobility, anticipating failures or troubles in a preventive or predictive way and to participate actively to that efficient and sustainable mobiliy system. These Mobility techdays in Auvergne-Rhône-Alpes will introduce some outstanding projects covering digital and connected devices or products, and sustainable mobility solutions : Infrastructures and smart grids, Connected vehicle and new Human-Machine interfaces, driving assistance/automated vehicle, Cybersecurity, Innovation, through uses and MaaS.
