An increasing amount of data available in different localization references is a barrier to future development of the transport community. The aim of the project LASDIM is to create a totally open environment that enables to explore, visualize, disseminate or re-use data in a common geo-localization reference. This will require specifying and building a new data model, authoritative reference and attractive for the data or service providers. The ClaireSITI platform will be used as an intelligent and multimodal system able to manage both the public transport and the road transport. The project will allow for global brainstorming on fast and real-time exchange of information with the aim of reducing the negative impact of transport. This will be a brand-new feature encouraging positive behaviour changes in and allow lower traffic congestion, reduce pollution levels and optimize emergency-response time.
