摘要
为研究不同空域复杂性条件下的飞行冲突探测策略,设计最小间距(MD)×汇聚角度(CA)×速度特性(SC)的被试内三因素重复测量实验方案,基于马尔科夫链的注视平稳分布概率和兴趣区注视时长分布特征,判断被试所采用的冲突探测策略并分析不同策略下的任务绩效指标.研究结果表明:在汇聚角度较大、最小间距更接近告警间隔的实验场景中,被试多采用距离-速度比(DV)策略;在汇聚角度较小、最小间距较小、航空器速度相同的实验场景中,被试多采用认知运动外推(CME)策略.多数情况下,采用CME策略判断飞行冲突的反应时更短、正确率更高.研究结果可为提高冲突探测的感知和预判能力提供参考.
Abstract
In order to study the flight conflict detection strategies under different airspace complexity conditions,a repeated within-subjects measurement experimental scheme with three factors of minimum distance(MD)×convergence angle(CA)×speed characteristics(SC)was designed.The conflict detection strategies adopted by the subjects were judged based on the stable distribution probability of fixation in Markov chain model and the distribution characteristics of fixation duration in the area of interest,and the task performance indexes under different strategies were analyzed.The results show that in the experi-mental scenarios where the convergence angle is larger or the minimum distance is closer to the alarm interval,the subjects prone to adopt the distance-to-velocity ratio(DV)strategy.In the experimental scenarios where the convergence angle is smaller,the minimum distance is shorter,or the aircrafts speed are the same,the subjects prone to adopt the cognitive motion extrapolation(CME)strategy.In most cases,the CME strategy has shorter response time and higher accuracy in judging flight conflict.The research results can provide a reference for improving the perception and prediction ability of conflict detection.
