摘要
Abstract
In addition to mechanical characteristics of vehicle,driver′s perception also has certain effect on the oper-ation of the vehicle.However,quantitative and empirical analysis through field experiments is still relatively limited. Based on driving perception and force analysis,vehicle operation is divided into three acceleration/deceleration states;which are acceptable,barely acceptable,and unacceptable vehicles′operating states are determined by driver′s perception and vehicle speed.Driver′s perception data is recorded by in-vehicle observer,and vehicle speed data is collected by a high precision GPS (v-box).According to the Raff′s critical gap method,the critical thresholds of the three states are ob-tained.The results show that if the driver is in an acceptable state,the acceleration rate ranges from 0 ~3.28 m/s2 ;the deceleration rate ranges from -3.48~0 m/s2 .When vehicle operates normally,the critical thresholds of the three states rarely exceed the above ranges.Study results provide a reference to the understanding of vehicle operation characteristics and calibration of traffic simulation parameters.关键词
