Pedestrian Collision Avoidance System for Autonomous Vehicles

Robust Tunable Trajectory Repairing for Autonomous Vehicles Using Bernstein Basis Polynomials and Path-Speed Decoupling

“…Generally, there are two ways to calculate TTX online: using empirical estimates or by forward simulation. Schratter et al [7] use an empirical formula based on the current ego state and surrounding states to estimate TTB and TTS, and, finally, estimate the collision risk for decision-making of an emergency maneuver. Their proposed collision avoidance system can handle the pedestrian-crossing scenario in an occluded area.…”

Modeling Interactions of Autonomous Vehicles and Pedestrians with Deep Multi-Agent Reinforcement Learning for Collision Avoidance

“…The influence of uncertainty in form of measurement noise (see (2)) is evaluated with a fixed noise level α AV = 0.05 over an interval of α ped ∈ {0.0, 0.1, 0.2, 0.3, 0.4, 0.5}. This approach focuses on the AV's response under uncertain pedestrian behavior as the pedestrian's estimations of its environment are unreliable, i.e., the pedestrian is likely to make a wrong crossing decision.…”

“…Modern cars are equipped with pedestrian crash avoidance mitigation (PCAM) systems to avoid such pedestrian-related collisions, making them a crucial component of future autonomous vehicles (AVs). In [2], a modern PCAM system is developed on basis of reachability analysis in conjunction to a situation-aware trajectory planner. The necessary use of a reliable dynamic model for the movement of the pedestrian poses real-world challenges and neglects the sequential decision making process of the situation.…”

Identification of risky locations based on the CAS device-based alerts generated from moving vehicles: A Case study

“…From the result it is observed that 15.04% length of the highway requires remedial measures through road safety programs. Markus Schratter et al [21] proposed a system with a combination of pedestrian collision avoidance system and a situation awareness planner to control critical situations with pedestrians at occluded areas. Collision avoidance system is combined with a situation awareness planner considering the sensors visibility and capability of the avoidance system to provide a set of collision free trajectories to optimise the driving velocity.…”
