Threat assessment and collision avoidance strategies at traffic intersections
Intelligent transportation systems, collision avoidance, threat assessment algorithms
Recent advances in sensing and vehicle technologies have enabled significant progresses in the area of the active safety of passenger cars.  Safety systems, assisting the driver in complex accident avoidance maneuvers, are already available in passenger cars. Even more complex vehicle systems, with autonomous driving capabilities, are expected to be available soon. But automobile technologies present several interesting safety challenges. For instance, algorithms predicting dangerous situations are necessary to prevent accidents or faulty interventions of existing safety systems.  
Problem description
In this thesis, we are interested in threat assessment algorithms for traffic intersections’ scenarios. The objective is to provide to each vehicle mechanisms enabling decision making with respect to a potential collision. More precisely, each vehicle must be able to assess, from the data provided by sensors, if other vehicles are following a (not know) conflicting trajectory. This thesis should focus on the fundamental aspects of the underlying prediction algorithms and decision making problems.  
Purpose and goals
The goal of this master thesis is to study, develop and demonstrate “provable safe” decision and control algorithms for traffic intersection scenarios. In particular, given a set of vehicles following a given trajectory (not know to the other vehicles), the objective is to design a threat assessment algorithm able to identify other vehicles’ dangerous trajectories. Furthermore, formal analysis methods verifying a set of safety requirements should be provided for a subsequent control strategy. The resulting control/decision algorithms should be integrated in cutting edge simulation environments such as, for instance, PreScan, and the DENSO's demo vehicles (Volvo S60) may also be used to collect data in real setups.
