Research on One-Way Multi-Lane Overtaking Based Warning System

In order to improve the driving safety of one-way multi-lane overtaking behavior, this paper designs and validates an overtaking warning system. By analyzing the dynamic characteristics and potential risks of the overtaking process, the prediction model of overtaking time and target lane safety gap is constructed, key parameters such as safety time distance and vehicle parameters are introduced, and three levels of danger levels and corresponding warning strategies are set. MATLAB simulation is used to verify the design of three types of typical overtaking scenarios (safe, cautious, and dangerous), and the test results show that the system can effectively differentiate the risk levels and output the warning consistent with the expectation, which verifies the reasonableness of the model and strategy
