This repository contains the multimodal transportation network of Ile-de-France which is modelled by graph layers corresponding each to a different transportation mode, interconnected together into a multilayer graph. The graph of the transport networks is provided under various format (graphml, gml, edge and vertex files format). The network is composed of three layers: the road network, the train network is a hybrid commuter rapid transit system in France serving Paris and its suburbs and the subway network which is only present inside the Paris city limits. To build this graph, multiple geospatial datasets, namely the road network from the French National Geographic Institute and the rail transport network (train and metro) from OpenStreetMap were aggregated. Each node in the graph is either a road intersection, a rail station or a metro station. A key feature of the proposed multimodal transportation network is its modelling of transitions between different transport modes during a given trip. Cross-layer transition modelling is ensured by adding cross-layer appropriate edges between layers.
