Based on the platform on driving simulation,through selecting highway and urban road as experimental environment,the index of mental workload and driving behaviors of drivers have been monitored through the whole process.Each experiment lasts about 15 minutes.In the experiments HRV is used as assessment index of mental workload,while the use of rearview mirror,steering lamp and vehicle speed are used as indices on driver behavior.The experimental results show that compared with normal driving,when cell phone is used in driving,the phenomenon appeared-the driver's LFNU and HFNU decrease,and LF/HF increases obviously and TP increases,too.Excluding the effects of driving fatigue,it can be preliminarily concluded that the phenomenon is caused by increment of mental workload by using of cell phone.Under the situation of limited cognitive resource,the increment of mental workload causes the different degree decrease of abilities about information acquisition,use of steering lamp,gear position operation and speed control.In a word,using cell phone in driving can cause the increase of mental workload,and can produce negative effect on driving behaviors and generate potential safety hazard.Therefore,the departments concerned should make legal limits on using cell phone in driving to reduce risks of traffic accidents.
