The objective of the operation is to gather and enrich all the mobility data of the Lyon-St Etienne metropolitan area, foreshadowing a real mobility resource center by centralizing multimodal data and facilitating intermodal journeys. The operation must make it possible to offer users, via adapted digital interfaces, the most complete and up-to-date information possible by favoring less polluting travel than autosolism (collective transport, carpooling, active modes ...), it must allow the facilitation of their travel. The project integrates more partner networks, new types of networks and aims to improve public action on mobility through data sharing, service coordination workshops and SMTAML support for data producers.
