  In Europe, 20% of road crashes occur at intersections. In recent years,
evolving communication technologies are making V2V and V2I faster and more
reliable; with such advancements, these crashes, as well as their economic
cost, can be partially reduced. In this work, we concentrate on straight path
intersection collisions. Connectivity-based algorithms relying on 5G technology
and smart sensors are presented and compared to a commercial radar AEB logic in
order to evaluate performances and effectiveness in collision avoidance or
mitigation. The aforementioned novel safety systems are tested in a blind
intersection and low adherence scenario. The first algorithm proposed is
obtained by incorporating connectivity information to the original control
scheme, while the second algorithm proposed is a novel control logic fully
capable of utilizing also adherence estimation provided by smart sensors. Test
results show an improvement in terms of safety for both the architecture and
high prospects for future developments.
