CAMAF: A framework to increase safety on the road

Cooperative Intelligent Transportation Systems (CITS) deploy the Cooperative Awareness Basic Service to exchange Cooperative Awareness Messages (CAMs) among road C-ITS entities, e.g., vehicles and roadside units (RSUs). CAMs support vehicular safety and traffic efficiency applications that require continuous status information of surrounding C-ITS entities. These messages provide awareness of traffic information in the Non-Line of Sight (NLOS) of the vehicle and are an essential feature to guarantee safety in vehicles. Typically, applications to display CAMs depend on specific C-ITS hardware and software, which implies that each researcher and the industry must develop an application in software and hardware. In this paper, we propose a framework to support research on CAMs through a monitoring dashboard, deploying a portable environment named CAM Application Framework (CAMAF); it manages the received CAMs and updates a corresponding specific monitor for each active C-ITS entity. Each monitor is configurable by choosing CAM fields and making or changing algorithms to display the desired information. We have tested our proposal in a C-ITS testbed with real live traffic.
