Optimization Control Method for Ramp Confluence Based on Conflict Avoidance under the Environment of CVIS

匝道合流区是城市快速路冲突频发区,研究匝道合流控制方法对于提高道路的通行安全具有重要意义。文中基于冲突规避原则提出了CVIS环境下的匝道合流控制方法。考虑车辆特性和行驶的约束,以合流区冲突最小为目标,优化行车过程。经仿真验证,该方法能有效避免冲突并提高车辆行驶的舒适性,为匝道合流区的冲突管理提供控制方法。

Ramp confluence area is a frequent conflict area of urban expressway.The study of ramp confluence control is of great significance for improving road traffic safety.In this paper,the optimal control method of ramp confluence in CVIS environment is proposed based on the conflict avoidance control principle.Considering the characteristics of vehicles and the constraints of driving,and aiming at minimizing the collision in the confluence area,the driving process of vehicles is optimized.The simulation results show that the proposed method can effectively avoid conflicts,improve vehicle riding comfort,and provide a control method for the conflict management of ramp confluence area.
