本研究的目的是优先考虑可以通过ACN（自动碰撞通知）信号传输的变量。传输这些变量的主要目的是帮助早期识别那些具有时间关键性损伤的乘员。出于本研究的目的，将所有迈斯3+损伤归类为时间关键型。优先考虑碰撞变量的基础是基于它们在国家汽车抽样系统-耐撞性数据系统（NASS/CDS）数据集中识别迈斯3+受伤乘员的能力。在这项研究中，多变量模型，以代表碰撞事件的基础上，从1997年至2003年的历史碰撞数据。分析建立了数据库中所有乘用车的碰撞属性和碰撞结果之间的关系。由此产生的分析提供了按重要性顺序排列的碰撞变量。碰撞严重度（Δ V）被认为是所有平面碰撞方向的最重要的变量。其他碰撞变量的增加提高了伤害预测算法的准确性。对于正面碰撞，重要的二次碰撞变量包括：三点式安全带的使用，多次碰撞，乘员年龄和超过6英寸的存在。入侵。对于近侧碰撞，最重要的次要变量是乘员年龄，狭窄的对象碰撞，和入侵的存在。对于远侧碰撞，最重要的二次碰撞变量是三点式安全带的使用和窄物体碰撞的发生。翻滚被认为是一种高风险事件，如果不使用三点式安全带，则预测与Delta-V无关的高伤害风险。该文件显示了碰撞和乘员变量的碰撞方向的相对重要性。
The objective of this study was to prioritize the variables that could be transmitted with an ACN (Automatic Crash Notification) signal. The main purpose of transmitting these variables is to assist in early identification of those occupants with time critical injuries. For the purposes of this study, all MAIS 3+ injuries were classified as time critical. The basis for prioritizing crash variables was based on their ability to identify MAIS 3+ injured occupants in the National Automotive Sampling System-Crashworthiness Data System (NASS/CDS) dataset. In this study, multivariate models to represent crash events were developed based on historical crash data from the years 1997-2003. The analysis established a relationship between crash attributes and crash outcomes for all passenger vehicles in the database. The resulting analysis provided a ranking of crash variables in order of importance. Crash severity (Delta-V) was found to be the most important variable for all planar crash directions. The addition of other crash variables improved the accuracy of the injury prediction algorithm. For frontal crashes important secondary crash variables include: 3-point belt usage, multi-impact crashes, occupant age and the presence of more than 6 in. of intrusion. For near-side crashes, the most important secondary variables were occupant age, narrow object crashes, and the presence of intrusion. For far side crashes, the most important secondary crash variables were 3-point belt usage and the occurrence of a narrow object crash. Rollover was found to be a high risk event that predicted high injury risk independent of Delta-V if 3-point belts were unused. The paper shows the relative importance of the crash and occupant variables by crash direction.
