TL;DR: Numerical results show that the proposed model provides an accurate estimation for car-following collision risk with a relatively low complexity, taking into account the impacts of vehicle dynamics, driver reaction capacity, and external environment on rear-end collisions.
Abstract: This paper presents a probabilistic decision-making framework for rear-end collision avoidance systems, focusing on modeling the impact of major collision-causing factors on the occurrence of accidents. Decisions on when and how to assist drivers are made using a Bayesian network approach according to collision risk evaluation results, given a prior probabilistic knowledge. The structure of the Bayesian network model is learnt using a K2 algorithm with a practical dataset. To provide adequate response time for drivers, we also predict collision probability in the next monitoring interval using a Kalman filter model. The prediction accuracy is evaluated with different use cases and compared to real scenarios with the obtained dataset. To make our framework more relevant to practical applications, we also discuss the corresponding safety control strategies by classifying collision risk into high and low levels. In addition, the proposed model is evaluated through experiments including simulations and road tests. In the simulations, the algorithms are tested in different scenarios with various configurations of weather conditions, driver response capability, and vehicular dynamics. In order to demonstrate collision avoidance performance, the proposed model is also compared to existing schemes. In the road tests, the algorithm is embedded into an unmanned vehicle with predefined parameters to evaluate the impact of computational complexity on rear-end collision avoidance. Numerical results show that the proposed model provides an accurate estimation for car-following collision risk with a relatively low complexity, taking into account the impacts of vehicle dynamics, driver reaction capacity, and external environment on rear-end collisions.

TL;DR: Simulation and road test experiment results demonstrate that the proposed method is effective to avoid rear-end collision by emergency steering manoeuvre and some aspects, like vehicle lateral stability, emergency manoeuvre selection and simultaneously emergency manoeuvres are discussed as well in this work to apply this collision avoidance method into practical application.
Abstract: Rear end collision is one hazard accident for an autonomous vehicle. Emergency braking has already been deeply researched and applied into some new model vehicles to avoid rear-end collision or mitigate its impacts. Emergency steering is another promising method to enhance vehicle safety; this kind of collision avoidance approach remains to be carefully studied. To fill this gap, this work proposes an emergency steering based rear-end collision avoidance approach concerning required safe distance as safety index. Vehicle dynamics, Tire Slip Angle and Segal lateral force model, are concerned to obtain the vehicle states. Monte Carlo simulation is executed to determine the value of required safe distance when encountering with a stationary and a suddenly decelerating target vehicle at different velocities. Safe Distance Margin and quantised influence two indexes are proposed to assess the influence of measurement uncertainty. Simulation and road test experiment results demonstrate that the proposed method is effective to avoid rear-end collision by emergency steering manoeuvre. Moreover, some aspects, like vehicle lateral stability, emergency manoeuvre selection and simultaneously emergency manoeuvres are discussed as well in this work in order to apply this collision avoidance method into practical application.

TL;DR: The results show that the collision avoidance system that uses MQTT protocol can accurately generate alert messages 90% of the time when there are only ten or less than ten vehicles, and the system is easy to implement without requiring extra equipment.
Abstract: Rear-end vehicular collision due to illegally parked and unusually slow-moving vehicles on National Highways can be avoided if drivers can get alert messages and full information needed to make an objective judgment about what is ahead. A lot of work has been done on collision avoidance strategies using various networking techniques. IoT based solutions area recent research trend. The objective of this project is to develop an intelligent system that will identify illegally parked and the slow-moving vehicles on highways using the message queuing telemetry transport (MQTT) protocol that enables vehicles to exchange their real-time information, such as velocity and position, with the neighbouring vehicles through brokers (also called as servers). MQTT being a lightweight IoT protocol for machine to machine communication is useful for an effective data transfer between vehicles. An optimal algorithm has been developed to accurately identify every vehicle in the vicinity of the region of interest and to calculate both speed and position of the vehicle and transfer data from one vehicle to another vehicle. The new algorithm is implemented in a Raspberry Pi using a global positioning system (GPS) module. The results show that the collision avoidance system that uses MQTT protocol can accurately generate alert messages 90% of the time when there are only ten or less than ten vehicles which is also the case in most highways. Also, the system is easy to implement without requiring extra equipment. Hence the new technique can be used in various types of vehicles, especially cargo trucks and buses that use the highways frequently.

TL;DR: A rear-end accident forensics model for smart forensics is first developed to collect the information about road environments, vehicle information stored on edge infrastructures, and data logging within the accident scene and a liability determination scheme based on multi-access edge computing is proposed.
Abstract: Due to the multiplicity of rear-end collisions and the complexity of collision forensics, it is necessary to reconstruct and evaluate the accident. In this paper, we propose a rear-end forensics and liability determination scheme based on multi-access edge computing (MEC) to facilitate rapid smart forensics and determine the accident liability reasonably. Specifically, a rear-end accident forensics model for smart forensics is first developed to collect the information about road environments, vehicle information stored on edge infrastructures, and data logging within the accident scene. We then establish a data chain of rear-end incident (CRI) from the forensic information closely related to vehicles involved in the collision. The possible security state (PSS) of the rear vehicle can be obtained by decoding the actual state (AS) of the front vehicle in the CREI using the Hidden Markov Model (HMM). Accordingly, the rear-end collision evaluation metrics is set up, calculating the estimated liabilities (ELs) for each vehicle based on the driver’s attention level (AL) deduced from the proposed model. Finally, the liability of involved vehicle can be determined by HMM-based driver’s AL detection algorithm. The performance evaluations show that the proposed smart forensics and rear-end liability determination scheme can determine rear-end liability faster and more reasonably.

TL;DR: This study discusses the protocol used by vehicles to communicate with each other and cooperate to avoid a rear-end or multi-vehicle collision.
Abstract: The development of communication between vehicles allows the development of a safety system based on cooperation. Through the cooperation of one vehicle with another vehicle will work together to improve the level of traffic safety. On toll roads, high-speed and sequential vehicles have the potential to experience rear-end collisions and multi-vehicle collision (pileup). Delay in braking from vehicles behind a vehicle that brakes suddenly is the main cause of a multi-vehicle collision. The braking delay is greater if the vehicle is further away from the vehicle which is the cause of a multi-vehicle collision. Through V2V communication, braking by a vehicle can be notified to other vehicles far behind it. This will speed up the braking response so that multi-vehicle collision can be avoided or reduced impact. Devices used to avoid rear-end or multi-vehicle collision in a cooperative manner are recognized as Cooperative Rear-end Collision Avoidance System (CRCAS). The device is part of Advanced Driver Assistance Systems (ADAS) and is a refinement of RCAS. This study discusses the protocol used by vehicles to communicate with each other and cooperate to avoid a rear-end or multi-vehicle collision.

TL;DR: Results show that a negative ULVI value can reduce rear-end collision risk during starting process compared with two scenarios of stopping and car-following processes, and plays a key role in car- following safety in ACC or automotive platoon driving.
Abstract: In this study, the simplified desired safety margin (DSM) model as a car-following strategy is introduced. Based on this, we introduce an uncertainty level of velocity information (ULVI) parameter in the DSM model. Three scenarios as starting, stopping, and car-following processes are set to investigate the impact of ULVI on rear-end collision in V2V communication environment. Results show that a negative ULVI value can reduce rear-end collision risk during starting process compared with two scenarios of stopping and car-following processes. Furthermore, ULVI is not conducive to reducing rear-end collision risk during car-following process unless ULVI with a negative random value exists throughout the entirety of the car-following process. Therefore, ULVI plays a key role in car-following safety in ACC or automotive platoon driving. Findings are useful for designing different control strategies in different traffic scenarios by considering the effect of ULVI that reduce rear-end collision risk in ACC or automotive platoon driving.

TL;DR: This work proposes an algorithm that includes vehicle accident identification and rear-end collision warning that is primarily used for curved road conditions and has good performance, and the false alarm rate does not exceed 1%.
Abstract: With the combination of vehicle information and communication technology, there is a new opportunity to solve the problem of rear-end collision in the field of transportation. Based on 802.11p, vehicles equipped with the WAVE (Wireless access in Vehicular Environment) standard can communicate each other in real time. When an accident occurs, vehicles within range can receive warning information quickly through inter-vehicle communication. The drivers will have enough time to calmly brake to stop and also reduce the risk of secondary collision. In order to prevent secondary collisions, we propose an algorithm that includes vehicle accident identification and rear-end collision warning. If it is calculated that the vehicle will collide, the system will notify the driver to take brake. The algorithm is based on the historical path of the vehicle and is primarily used for curved road conditions. The results show that the algorithm has good performance and the false alarm rate does not exceed 1%.
