基于多因素耦合的机动车驾驶人不安全行为风险分析
Risk Analysis of Unsafe Behaviors of Motor Vehicle Drivers Based on Multi-factor Coupling
摘要
Abstract
To explore the influence of the coupling relationship among unsafe behaviors of motor vehicle drivers on a multi-factor coupled road traffic system,a combined model of the N-K model and the coupling degree model were constructed based on a total of 739 accident data from the National Vehicle Deep Investigation System(NAIS)database from 2017 to 2019.The causes of road traffic accidents are ex-plored through the N-K model.The risk coupling value function of drivers'unsafe driving behaviors was constructed in combination with the coupling degree model to study the coupling effect between unsafe be-haviors.The research finds that the level of road traffic risk shows a significant increasing trend with the in-crease in the number of coupling factors.Among them,the interaction information value T(a,b)of the driver-vehicle two-factor coupling is 0.0167,which is 9.01 times the driver-road interaction information value and is also the combination with the highest risk in the two-factor coupling.The value of the four-factor coupling interaction information reached 0.0220,which indicates the strongest risk effect.Among the unsafe behaviors of drivers,speeding(with a risk coupling value of 0.0822)and failure to yield as required(with a risk coupling value of 0.0683)are significantly higher than other behaviors.The number of accident cases caused by these two behaviors accounts for 43.4%of the total number of cases,and they are the core risk sources causing traffic accidents.关键词
