Effect of drivers'action points on traffic hysteresis and its optimization strategy
摘要
Abstract
[Background]As a typical nonlinear phenomenon in traffic flow,hysteresis formation is closely related to the physiological and psychological characteristics of drivers.[Objective]To inves-tigate the effect of random action points(APs)on traffic hysteresis as well as to propose optimization strategies to reduce the intensity of hysteresis,thereby alleviating traffic oscillation and improving driving safety.[Methods]First,the probability distribution function of the AP is obtained by fitting the Parabola2D function,and the AP distribution is introduced into an intelligent driver model(IDM)to simulate and analyze the hysteresis effect.Subsequently,the proposed model is used to intervene the driver's perception and provide decision-making information under specific speed-difference conditions to improve the hysteresis effect.Thus,the hysteresis effect is improved.[Data]The NG-SIM dataset obtained by the Federal Highway Administration of the U.S.Department of Transporta-tion is processed with noise reduction and the AP data are extracted,based on which the probability distribution function of the AP occurrence is fitted to improve the car-following model and analyze the hysteresis effect.[Results]The proposed car-following model can capture changes in driver-per-ception decision points more accurately than the baseline IDM.The correlation analysis of the hyster-esis effect reveals that the AP distribution parameter c has a significant positive correlation with the hysteresis intensity,is negatively correlated with the hysteresis intensity when the values of z0,b,and d are small,and becomes positively correlated after reaching a certain threshold value.Additionally,timely intervention in driver perception and provision of decision-making information can effectively attenuate the hysteresis effect,and the hysteresis intensity gradually decreases with an increase in the intervention speed-difference range;however,further improvements cannot be realized when the speed-difference intervention range reaches a certain threshold.关键词
