单调环境下驾驶人的警觉性时变规律
The Variation of Drivers’ Vigilance with Time under the Monotonous Environment
摘要
Abstract
Lack of vigilance is an important cause in traffic accident ,especially in monotonous environment .Highway design reduces the driving task mainly to a lane-keeping manoeuvre .Such a task is monotonous ,and the road is highly predictable , providing little stimulation.Under this environment ,the drivers’ vigilance may easily decrease .In order to study the varia-tion of drivers ’ vigilance with time under the monotonous environment ,a simulator test was carried out .In this test ,simula-tion software was used to build the driving environment ,in which ten drivers participated voluntarily .Subjective fatigue state was measured by using the subjective fatigue scale ,and the MP150 was used to collect the Electrocardiograph ( ECG) data of the drivers.Besides,the divers also need to found specific signals and report it .The result shows that drivers ’ miss rate of signal has changed under the monotonous environment .In the final 30 min,the drivers’ miss rate of signal increased from 8%to 32%.The drivers’ heart rate has no significant difference during the driving .However,the subjective fatigue level has significant difference .It is concluded that within one-hour driving under the monotonous environment ,there is no fatigue on physical ,but drivers ’ vigilance decreased in 30 min after the driving .It is also proved that drivers ’ vigilance decreased under the monotonous environment .关键词
