| 摘 要： | 为量化不同驾驶方式下车辆与航空器行驶风险，提出车辆与航空器交叉运行冲突评估模型，该模型将特种车辆驾驶方式分为激进、稳定、保守3类，综合驾驶特性和管制规则定义车辆速度演化规律，结合运行场景、间隔配备等要素确定冲突条件，并基于航空器与车辆实时速度、位置变化构造冲突评估模型。研究结果表明:冲突评估模型能够计算车辆与航空器在十型交叉口的冲突概率；激进方式下车辆先于航空器通过交叉口，风险概率均值相对最大，为0.679；保守方式下航空器先于车辆通过交叉口，最大间隔是安全间隔的4.7倍；稳定驾驶方式可兼顾安全和效率。本文模型能再现十型道口车辆与航空器交叉运行冲突产生、发展及解脱过程，计算结果可用于场面实时冲突识别和预警，能够为机场危险源识别和风险管控提供依据。

| Abstract: | In order to quantify the driving risk of vehicle and aircraft under different driving modes,an assessment model on the cross running conflict of vehicle and aircraft was proposed.The model divided the driving modes of special vehicle into three categories: aggressive,stable and conservative.The evolution law of vehicle speed was defined based on the driving characteristics and control rules,then the conflict conditions were determined in combination with the running scenes,separation establishment and other elements,and the conflict assessment model was constructed based on the real-time speed and position change of aircraft and vehicle.The results showed that the conflict assessment model could calculate the conflict probability of vehicle and aircraft at the cruciform intersection.Under the aggressive mode,the vehicle passed through the intersection before aircraft,and the average risk probability was 0.679,which was the maximum of the three modes.Under the conservative mode,the aircraft passed through the intersection before vehicle,and the maximum separation was 4.7 times of the safety separation.The stable driving mode could meet both safety and efficiency.This model can reproduce the generation,development and liberation process of cross running conflict between vehicle and aircraft at the cruciform intersection,and the calculation results can be used for airport real-time conflict identification and early warning,and provide the basis for the hazard source identification and risk control. |
