Globally, over half of road traffic deaths are vulnerable road users. Although substantial efforts are being made to improve VRU safety from engineering solutions to law enforcement, the death toll of VRUs' continues to rise. The emerging technology, Cooperative Intelligent Transportation System (C-ITS), has the proven potential to enhance road safety by enabling wireless communication to exchange information among road users. Such exchanged information is utilized for creating situational awareness and detecting any potential collisions in advance to take necessary measures to avoid any possible road casualties. The current state-of-the-art solutions of C-ITS for VRU safety, however, are limited to unidirectional communication where VRUs are only responsible for alerting their presence to drivers with the intention of avoiding collisions.

It is generally agreed the 4G mobile broadband services can support such V2I road applications. However, how well 4G mobile services can meet the requirements is less understood. In this paper, we propose 4G based V2I road data communication mechanism supporting publish- subscribe paradigm to multicast road safety messages according to the user location. In fact, we introduce advanced filtering method based on the travelling road and the heading direction of the users to filter the most relevant road events, not only limited to the conventional proximity based filtering. Thus communicating road event notifications to the most relevant road users through an infrastructure-less decentralized application layer system is the main focus of our work. A prototype system called "CoRES: Cooperative Road Event Sharing app" is developed to evaluate the approach using an actual on-the- road experiment showing that users can receive reliable notifications at low latency and high reliability.
