TL;DR: In this article, a vehicle rear-end collision alarm system is provided with a distance measuring device measuring a distance between own vehicle A and the vehicle B running ahead of own vehicle, an information display device displaying the received running information from the vehicle A ahead of its own vehicle and images of a road situation ahead of itself in the direction of advance.
Abstract: PROBLEM TO BE SOLVED: To give proper rear-end collision alarm by grasping running information of a vehicle running ahead of own vehicle and images of a road situation ahead of own vehicle in the direction of advance in a vehicle rear-end collision alarm system giving an alarm to prevent the rear-end collision against the vehicle running ahead of own vehicle while the vehicle run. SOLUTION: This vehicle rear-end collision alarm system is provided with a distance measuring device 1 measuring a distance between own vehicle A and the vehicle B running ahead of own vehicle, an image pickup device 2 photographing a road situation ahead of own vehicle A in the direction of advance, a communication device 2 receiving running information of the vehicle B ahead of own vehicle sent from the vehicle B ahead of own vehicle and images of a road situation ahead of own vehicle in the direction of advance and transmitting running information of own vehicle A and images of a road situation ahead of own vehicle in the direction of advance, an information display device 4 displaying the received running information from the vehicle B ahead of own vehicle and images of a road situation ahead of own vehicle in the direction of advance, and an alarm device 5 giving a rear-end collision alarm by judging a possibility of rear-end collision against the vehicle B ahead of own vehicle based on a distance between own vehicle and the vehicle B ahead of own vehicle, its running speed, and a running speed of own vehicle A.

TL;DR: In this paper, a method of indicating the operation state of the rail way crossing barrier is provided to prevent the rear end collision and the collision due to the defect of blocking action of the railway crossing barrier and to improve the train operation efficiency.
Abstract: PURPOSE: A method of indicating the operation state of the rail way crossing barrier is provided to prevent the rear end collision and the collision due to the defect of blocking action of the rail way crossing barrier and to improve the train operation efficiency. CONSTITUTION: The method of indicating the operation state of the rail way crossing barrier comprises: train approach detecting step(S11) to continuously detect the approach of a train to pass through the rail way crossing; blocking rod position detecting step(S12) to detect the position of a blocking rod when the approach of a train is detected according to the performance of the train approach detecting step; position transmitting step(S13) to transmit the data about the position of the crossing bar detected after performing the crossing bar position detecting step; and returning to the train approach detecting step when the crossing passage of the train is completed according to the detection of the completion of the crossing passage of the train after performing the position transmitting step.

TL;DR: In this paper, the driver's attention distribution, information extraction and judgement process and the reaction process are all incorporated into a conceptual model of the driver to predict the closed-loop nature of collision response performance and explain how the driver might use RECAS warnings.
Abstract: Several driver-performance factors contribute to rear-end collisions: driver inattention, perception/ reaction time, and limitations in the human visual system Although many evaluations have examined driver response to various Rear- end Collision Avoidance Systems (RECAS) display and algorithm alternatives, little research has considered creating a quantitative model of driver performance to evaluate design alternatives. Current considerations of driver behavior in developing warning algorithms tend to ignore the fundamental problem of driver inattention and assume a fixed driver reaction time with no further adjustment after the initial response. A more refined model of driver response to rear-end crash scenarios can identify more appropriate and timely information to be displayed to the driver. The driver's attention distribution, information extraction and judgement process and the reaction process are all incorporated into a conceptual model of the driver. The model developed predicts the closed- loop nature of collision response performance and explains how the driver might use RECAS warnings
