摘　　要：通过建立车速时变的两难区数学模型来获取各车辆两难区长度范围,研究分析车速、黄灯时间、车辆加减速度、反应时间与两难区之间的影响关系.根据黄灯启亮时车辆的加减速情况,采用黄灯时间由小到大循环判断的预测方法,提出两难区车载预警和黄灯时间控制策略,该策略可有效降低车辆陷入两难区事件的发生概率,减少交叉口车辆交通事故.The vehicle dilemma zone length range had been got through the dilemma zone model where the speed was changed from moment to moment. The dilemma zone effect relationship was analyzed in the aspects of yellow light time, vehicle＇s acceleration and decelera- tion, vehicle speed, and reaction time. According to the vehicle＇s acceleration and deceleration conditions, using the prediction methods of amber lights time to cycle judgment, dilemma zone amber lights time control strategy and vehicle warning control strategy were proposed. These strategies could reduce the incidence of being involved in the dilemma zone events, and decrease the traffic accidents.
