The invention discloses an accident risk improvement-oriented cooperative control method for a highway confluence area, and belongs to the field of traffic safety and intelligent traffic management control. According to the method, on the basis of an expressway confluence area in a vehicle-road coordination environment, an optimization control strategy is implemented on networked vehicles, and all vehicles participating in confluence are subjected to queue sequence and confluence time sequence adjustment, so that uniform and ordered distribution and confluence in the vehicle confluence process are realized; an optimization model with the minimum acceleration and jerk as the target is constructed within a reasonable range, the driving track in the vehicle converging process is optimized, the speed sudden change is prevented, the acceleration change condition is smoothed, and the accident risk caused by the vehicle lane changing and speed changing behavior is reduced. According to the method provided by the invention, on the premise of ensuring the traffic capacity, the potential accident risk in the confluence process is effectively reduced, and the safety guarantee level and the operation efficiency of the highway confluence area are improved.
本发明公开了一种面向事故风险改善的高速公路合流区协同控制方法,属于交通安全与智能交通管理控制领域。该方法基于车路协同环境下的高速公路合流区,通过对网联车辆实施优化控制策略,对参与合流的所有车辆进行队列顺序与汇入时序调整,实现车辆合流过程中的均匀有序分布和汇入;在合理范围内构建以最小化加速度与急动度为目标的优化模型,优化车辆合流过程行驶轨迹,防止速度突变,平滑加速度变化情况,减少车辆换道变速行为引发的事故风险。本发明提出的方法在保证通行能力的前提下,有效降低了合流过程中的潜在事故风险,提升了高速公路合流区的安全保障水平与运行效率。
