摘要

Vehicular networks reflect user mobility behavior and present complex microscopic and macroscopic mobility patterns. Microscopic mobility is often simplified in macroscopic systems and we argue that its impact is too largely neglected. Notwithstanding improvements in realistically modeling and predicting mobility, few vehicular traces - especially complex microscopic ones - are available to validate such models. In this paper, we present a realistic synthetic dataset of vehicular mobility over two daily traffic peaks in a small area: the Europarc roundabout in the town of Creteil, France. We outline how the description and comprehensive representation of local mobility at an intersection, such as the roundabout chosen here, is important for any interpretation made of it.
