Paper Abstract

In this paper, a mathematic model of rear-end accident based on system dynamics theory is proposed, and a beforehand alarm system against vehicle rear-end accident is designed. Driver’s physical reaction time and perception process are involved in this model, and after calculating the system installed in the following vehicle can predict whether the rear-end accident will occur. In the paper, the model’s establishment, the alarm system’s structure and working principle are described in detail and the design of relevant hardware and software is given. The system ran well in the test, and it has high liability, low cost, and easy node- expanding, which has a bright prospect of application and popularization.
