Rear-End Collision Velocity Reduction System

Abstract: Japan has a higher rate of rear-end collisions than any other kind of traffic accident and the causes of rear-end collisions were investigated. Accident statistics were used to conduct a statistical traffic accident analysis while a questionnaire was used to conduct a detailed traffic accident analysis and simulation was then used to perform traffic accident analysis. The results of the traffic accident analysis suggested that many of these accidents were caused by lack of attention during daily driving. Research was conducted to determine what kind of collision avoidance systems would be effective. A system was developed that is effective in reducing the collision velocity during rear-end collisions by making up for driver delays in recognition, judgment and operation by means of brake control and external sensing technology using millmeter wave radar sensor. This paper will discuss the testing and development of this new system.

Hybrid Collision Avoidance-Tree Resolution for M2M Random Access

Abstract: Wireless machine-to-machine (M2M) communication with synchronized traffic patterns plays an important role in many aircraft systems. Recent research has separately examined collision avoidance mechanisms, such as presmoothing and access barring, as well as collision resolution mechanisms, such as tree resolution, for M2M random access. In contrast, we examine the combination of collision avoidance and tree collision resolution into hybrid M2M random access protocols in the context of the popular Long-Term Evolution wireless system.

System and method for providing vehicle collision avoidance at an intersection

Abstract: A system and method for providing vehicle collision avoidance at an intersection include receiving vehicle parameters from a reference vehicle and environmental parameters from roadside equipment. The system and method also include processing a vehicle behavioral map based on the vehicle parameters and the environmental parameters and transmitting the vehicle behavioral map to a target vehicle. The system and method additionally include processing a confidence table based on the vehicle behavioral map and vehicle parameters provided by the target vehicle. The system and method further include providing a collision avoidance response based on the confidence table, wherein the collision avoidance response is provided to the target vehicle to avoid a possible collision with the reference vehicle at the intersection.

A collision avoidance algorithm for ship guidance applications

Abstract: The paper presents a collision avoidance algorithm for ship open sea navigation, based on an ad hoc modified version of the Rapidly-exploring Random Tree (RRT*) algorithm. The proposed approach is ...

Development of rear-end collision avoidance system

Abstract: RCAS (rear-end collision avoidance system) has been developed as a system of ASV (advanced safety vehicle). It is a driver assist system to avoid the rear-end collision by informing the distance headway. It also has automatic braking function in case of emergency and distance warning function to the trailing vehicle. This paper describes the outline of RCAS, techniques about the preceding vehicle recognition and collision potential hazard evaluation. And experimental results about distance headway warning and collision avoidance by automatic braking are reported.
