Vehicle's Safe Operation Region Research Based on Person-Vehicle-Road-Environment

Vehicle's safe operation region detenmination has a great significance to improve the traffic safety.Taking highway as a background,this article conducted a research for the vehicle's safe operation region through the evaluation factors of automobile's transport condition,driver's fatigue degree,weather conditions and so on.According to the vehicle's current condition and conbined with the operational factor,we aimed to caution the dangerous travel region,to reduce driver's burden and error in judgment.The algorithm part aimed at building the models separately by the following operation mode and passing operation mode for seeking the safe operation distance and region.At last,a virtual scene of vehicles' travel process was simulated.Lots of experiments showed that this safe operation region model has good stability and accuracy.
