Safety aspects of intelligent transport systems applied to road intersections.

Increasing traffic demands in urban areas lead to higher risks of accidents and car crashes, constituting a treat for road users like drivers, cyclists and pedestrians. Intersections are a sensitive part of the road infrastructure, due to the conflict points caused by traffic flows with different directions. Latest technology allows the management of intersections thanks to intelligent systems like Autonomous Intersection Management (AIM), along with other smart devices like CAVs, remote sensors, and optimization algorithms. Hence, Intelligent Transport Systems (ITS) provide a significant contribution in enhancing the safety levels in transportation infrastructures including road intersections. The implementation of these systems involve professionals of diverse backgrounds, spacing from civil to ICT engineering, and even to social, behavioral and financial studies. ITS still present some weaknesses that prevent them from becoming widespread and of common use, mainly related to costs and required computational power. Future research could be directed towards the development and refinement of algorithms, but also to the production of new sophisticated hardware and construction systems for road infrastructures.
