在现有交通系统四大要素的基础上加入车辆行驶状态,构成“人-车-环境-路-车辆行驶状态”五要素。“人-车-环境-路”因素采用打分的形式确定参数的分值,并利用层次分析法(AHP)计算参数权重来构建模型;“车辆行驶状态”因素则是引入加速度干扰的定义,建立了基于道路结构的加速度干扰模型。运用层级分析法建立了总的车辆行驶安全评价模型。在SuperM ap软件平台上进行G IS仿真,实现了将评价模型运用到实际车辆行驶过程的安全性评价中,该评价系统可以实时地对车辆当前的行驶安全性进行评价,并根据当前的安全状况对驾驶员进行安全提示。
Based on the four elements of the existing transportation system, the vehicle driving conditions are added to form the five elements of “people-vehicle-environment-road-vehicle driving status”. “Human-Vehicle-Environment-Road ” factors to determine the score of the parameters in the form of scoring, and using AHP to calculate the parameter weights to build the model; “Vehicle Driving State ” factor is the introduction of acceleration interference The definition of acceleration based on the road structure has been established. The overall vehicle driving safety evaluation model is established by using hierarchical analysis. GIS simulation is carried out on SuperMap software platform to implement the evaluation model applied to the safety evaluation of the actual vehicle driving process. The evaluation system can evaluate the current driving safety of the vehicle in real time, and according to the current safety status Safety instructions for the driver.
