    PC-Crash事故分析是根據事故現場的採集、記錄、調查與分析,將事故涉案車輛由碰撞後的終止位置反推回碰撞過程,再反推回碰撞前的運行狀態,來分析事故原因,然後根據有關法律規定進行責任認定。目前,我國在事故分析及責任認定上仍處於人工的分析判斷階段,這種方式顯然含有極大的人為因素,近年來發展起來的事故重建技術,為事故分析提供了科學的方法。

PC-Crash 交通事故再現軟體

PC-Crash事故分析是根據事故現場的採集、記錄、調查與分析,將事故涉案車輛由碰撞後的終止位置反推回碰撞過程,再反推回碰撞前的運行狀態,來分析事故原因,然後根據有關法律規定進行責任認定。目前,我國在事故分析及責任認定上仍處於人工的分析判斷階段,這種方式顯然含有極大的人為因素,近年來發展起來的事故重建技術,為事故分析提供了科學的方法。 

事故重建主要根據交通事故現場特徵,如碰撞後車輛位移、損壞程度、拖痕長度、路面情況等,運用力學動量守恆與能量守恆的基本理論,對事故發生過程進行推理與驗證。動量守恆理論以碰撞前的動量與碰撞後的動量總和相等為依據,根據車輛行駛方向與碰撞後的相關位置,來判斷事故前、後的車速變化及碰撞角度並完成參數檢測。能量守恆則以事故發生後車輛位移、損壞程度、碰撞角度等因素為依據,運用碰撞力學理論,來研究動能與位能的變化,從而推導出碰撞前、後車速和碰撞角度。重建工作就是將實際案例資料或實驗資料,通過統計回歸分析預測、事故現場模擬及碰撞軌跡分析等方法,來研究事故發生前、後車輛速度運行軌跡,最後將運算的結果或類比的運行以螢幕顯示或列印的形式輸出,具體說明事故發生過程。
  
Collisions up to 32 vehicles can be simulated in 2D and also in 3D. Car to car accidents, car to motorcycles , car to pedestrian accidents, occupant movement and also roll over can be calculated.
More than 3.000 licenses are in use worldwide up to now.

CCS (Client Conjoint Simulator) 客戶聯合模擬軟體

Our conjoint analysis systems all use a standardized market simulation tool (currently available as a component within the SMRT platform). You can deliver that same market simulation to your clients at a very reasonable cost. A single license covers the entire licensed organization, for unlimited users. The CCS is a special installation of SMRT that enables only the menus related to market simulations.
