The Application Research and Program Development of Vehicle-velocity Estimate in Traffic Accident Based on C#

在事故鉴定的过程中,车速确认是处理事故问题的所需依据。本文首先讨论以力学为理论基础的4种汽车碰撞情况下的碰撞规律和求解方法,得到在进行事故认定过程中,如何简化车速应用模型,利用原始调查数据,采用理论分析计算法鉴定车辆肇事速度等指标的若干技术手段;其次采用经典碰撞力学法,结合车辆碰撞事故的特点,研究几种比较实用的车辆肇事速度的计算公式;最后根据经典交通事故形态车速鉴定的计算流程,编写C#的应用程序。在C#应用程序的窗体界面选择相应碰撞类型,进入相关交通事故形态,输入有关参数值,点击命令按钮即可得出车辆肇事速度,并可方便地保存、修改和显示计算结果,有效地提高了车辆行驶速度鉴定的工作效率,缩短交通事故的处理周期。并列举实例。

In the process of traffic accidents assessment,speed confirmation is the basis of dealing with incidents.This paper firstly discusses the collison laws and solving methods of 4 scenarios of vehicle crash based on mechanical theory and concludes how to simplify the velocity application model and compute the vehicle speed indicator using theoretical analysis method based on the original survey data.Secondly,the classic collision mechanical method is applied in combination with the characteristics of vehicle crashes to study sevaral practical equations for speed estimation of vehicle.Finally,a program based on C# is developed according to the identified calculation process for vehicle speed of traffic accident.The vehicle speed is obtained by selecting the collision type,entering the relevant accident pattern,inputting the parameters and clicking the command button.The application can store,modify and display results conveniently,which improves the efficiency on vehicle speed identification and reduce the processing cycle of traffic accident.
