TL;DR: This paper provides a new system, that is called Cooperative Intersection Collision Avoidance Persistent (CICAP) system to avoid potential accidents at intersections and minimize accident risk, based on V2V communication and Real-Time Databases.
Abstract: Driving through intersections is potentially dangerous causing accidents and injury or death of the vehicle's conductor and/or his accompanists. Thanks to technological advances, many systems based on Vehicular Ad hoc Networks (VANET) are proposed to avoid collisions and improve road users' safety at intersections. In this paper, we investigate the use of Vehicle-To-Vehicle (V2V) communications and Real-Time Databases to mitigate collision risks, reduce the calculation time, and thus enhance safety at intersections. Specifically, we provide a new system, that we call Cooperative Intersection Collision Avoidance Persistent (CICAP) system to avoid potential accidents at intersections and minimize accident risk. Each vehicle stores its information as well as the nearby vehicles' information in a local Real-Time Database (RTDB). As it approaches to the intersection area, the vehicle queries its database and selects the target vehicles to execute the system. We used the VEINS framework to simulate different driving scenarios at urban intersections. Our simulation results confirm the proposed system's performance as a new cooperative intersection collision avoidance system based on V2V communication and RTDB.

TL;DR: It can be concluded that with the proposed algorithms, the initial hypothesis of the paper is verified, i.e. personalised warnings would get a greater acceptance by the drivers, of course without braking the safety limits.
Abstract: Advanced Driver Assistance Systems (ADAS) have been among the key innovations in the automotive market for over a decade, since they promote traffic safety. This tendency is strengthened even more lately, with the introduction of the autonomous vehicles. A plethora of ADAS exist in the market today, using common warning thresholds for all drivers. However, since we are not all driving the same way, by offering common systems for all the drivers, neither the acceptance nor the effectiveness levels of ADAS are optimal. This manuscript attempts to optimize the Collision Avoidance System (CAS) warning, through intelligent personalized algorithms. Starting with the identification of the dynamic parameters for driving behaviour modeling on the longitudinal road axis, the personalization parameters for ADAS are derived that form the basis for the algorithms developed. Also, based on literature studies, the safety boundaries for warning provision by the CAS are set and implemented in the algorithms. Specific personalized algorithms for the longitudinal road axis behaviour are developed, based on Time to Collision and Time Headway. The proposed algorithms based on Time Headway were assessed on-road with 10 drivers and were positively evaluated by the majority of the participants, with a varying degree of reliability and usability. Based on the results obtained, it can be concluded that with the proposed algorithms, the initial hypothesis of the paper is verified, i.e. personalised warnings would get a greater acceptance by the drivers, of course without braking the safety limits. Further improvements of the algorithm could be achieved, possibly through a better determination of the car following event, since its definition includes a few assumptions.

TL;DR: Application of sensor fusion to improve reliability of the collision avoidance system is presented and shows that collision avoidance information and avoidance paths by the system are complied with international regulations for preventing collisions at sea (COLREGs).
Abstract: Collision avoidance system for ships is an autonomous system that examines risk of collision between ships based on the data from navigational equipment and performs appropriate avoidance control to prevent the collision. Development of the system is relatively unexplored area compared to UGV and UAV. In this paper, based on analysis of techniques to facilitate autonomy of the UGV and UAV, application of sensor fusion to improve reliability of the collision avoidance system is presented. The result was verified via basic collision scenario based on practical simulation environment which is equivalent to the real ship, and shows that collision avoidance information and avoidance paths by the system are complied with international regulations for preventing collisions at sea (COLREGs).

TL;DR: In this paper, an acoustic and/or an optical signal generator is used to detect hazardous situations in the sense of a possible collision and an independent claim is also included for a method of operating a motor vehicle.
Abstract: The motor vehicle (1) has a quiet drive with a noise level lower than 65 dB, especially at least partly in the form of an electric motor and the collision avoidance system has an acoustic and/or an optical signal generator (2,3) that generates an acoustic and/or optical warning system independently of the driver's wishes. At least one sensor detects hazardous situations in the sense of a possible collision. An independent claim is also included for a method of operating a motor vehicle.

TL;DR: In this paper, the authors proposed a method for operating a vehicle having a collision avoidance system including a sensor for sensing potential other parties to a collision and having an evaluator, connected to a control unit, for evaluating a risk of a collision.
Abstract: A method for operating a vehicle having a collision avoidance system including a sensor for sensing potential other parties to a collision and having an evaluator, connected to a control unit, for evaluating a risk of a collision. It is proposed that when the other party to a collision comes relatively close in the lateral direction, an actuator system is activated in order to predefine a setpoint trajectory of the vehicle in order to avoid a lateral collision. In addition, a device for operating the method is provided.
