摘要
在国内交通检测手段的现实背景下,各种道路交通状态判别模型的可靠性和实用性一直不足。因此基于车道战略检测器和战术检测器的时间占有率提出了一种新的实用的相位交通状态判别模型,其中包括检测器的布设,占有率阈值的确定,相位交通状态的判别方法。通过VISSIM4.2仿真实验证明,该模型可以准确地判定符合人们主观判断的相位交通状态,并且可以很好地应用目前普遍采用的检测手段,实用性强。
Under the realistic background of domestic traffic detection technique, various road traffic status discrimination models are short of reliability and practicability. Thus a novel practical phase traffic status discrimination model based on the occupancy of lane strategy detector and lane tactics detector is presented, which includes the arrangement of detectors, the determination of occupancy threshold, the method of phase traffic status discrimination. The model mentioned above has been simulated with VISSIM4. 2. The results show that the model can discriminate the phase traffic status accurately which satisfy people＇s subject cognition, and apply the detection techniques well which are widely used currently with strong practicability.
