Understanding the dynamics of vehicles is a major issue in smart cities evolution. Impacts are preponderant in user guidance, fuel consumption, pollution, but also in instrumentation efforts to deploy the infrastructures of communication. Most intelligent transportation systems concentrate on macro-mobility with centralized decisions and global optimizations for whole cities. With the great development of autonomous cars and vehicle-to-vehicule communication systems, micro-mobility is again of special importance for opportunistic data dissemination and local decisions - for instance when arriving at traffic lights or when vehicles meet.
We believe in the strong integration of the two approaches - hybrid decentralized ITS.

Simulation tools are widely used to evaluate assumption correctness and performances of optimization algorithms. Several macroscopic vehicular mobility trace exist, but few detailed ones at the microscopic level. Most of macro traces integrate simplistic models for intersections and roundabout, while the complexity of this fine-grained mobility can greatly affect the global optimization. For that purpose, we propose a dataset describing a complex roundabout in Creteil, France.

The vehicular mobility dataset is mainly based on the real data collected by the General Departmental Council of Val de Marne (94) in France. The General Departmental Council of Val de Marne is a regional agency in charge - amongst other activities - of the transportation systems.

Different simulations tools and models are brought together to characterize and synthesize this trace:

• the street layout of Creteil roundabout area is obtained from the OpenStreetMap database,
• the traffic demand information on the traffic flow is derived from car counting and camera video analysis,
• the traffic assignment of the vehicular flows is performed by Gawron’s dynamic user assignment algorithm, included in the SUMO – Simulation of Urban MObility - simulator.
• the traffic light mechanism is derived from sequence adaptation manually documented in the regional transportation system.

The resulting synthetic trace includes a roundabout with 6 entrances/exits, 2 or 3-lanes roads, 1 bus road, 4 changing-lane spots, 15 traffic lights. It comprises around 10000 trips, over rush hour periods of two hours in the morning (7AM-9AM) and two hours in the evening (5PM-7PM).

The trace contains in each line the time (1-second granularity), the vehicle slope (not used), the vehicle lane, the vehicle angle, the vehicle type (vehicle or bus), the vehicle position, the vehicle coordinates on the two-dimensional plane (x and y coordinates in meters), the vehicle speed (in meters per second), and the vehicle id.
The trace is in CSV format, zipped.
