高速公路事故路段行车风险时空分布与演变特性研究
Research on spatio-temporal distribution and evolution characteristics of driving risks on highways with high risks
摘要
Abstract
To study the driving safety on some sections of highways prone to accidents,a method to characterize driving risks by field is proposed and the driving risk field model is built.The driving simulation experiment platform is employed to simulate different accident scenarios to obtain data samples.The risk field strength of some road sections is calculated based on the risk field model to investigate the distribution and evolution of driving risks in the temporal and spatial dimensions.Results show the risk field model is able to visualize the risks posed by multiple traffic factors on highways,effectively assessing the traffic risks.It is also revealed that the accident area occupying two lanes has greater fluctuations in the speed distribution curve,longer braking duration,and higher deceleration than the one with a single lane occupied.In addition,changing lanes poses more risks and dangers.The study may provide some insights for assessing driving risks on highways.关键词
