Vehicular communication networking (VCN) has been widely recognized as a promising solution to support safety-related applications in urban transportation systems. In VCN, efficient message dissemination can let vehicles be better aware of the potential risks and traffic anomalies, which is critical to road safety and traffic efficiency. Substantial studies have focused on the design of inter-vehicle message dissemination protocols. Nonetheless, most existing designs only consider the rapid end-to-end transmission, few of which take into account the broadcast coverage. In this paper, we propose a new message dissemination scheme in the urban traffic scenario by considering both the time constraint and the spatial distribution of data dissemination. Specifically, based on the temporal and spatial correlation of vehicle trajectory, relay vehicles are selected to construct a temporary warning network (TWN) for a rapid safety message dissemination in the regions of interest (ROI). Finally, we conduct extensive numerical experiments to validate the effectiveness of our method in various traffic scenarios.
