Although the number of deaths and injuries at level crossings in New Zealand is relatively low compared with the national road toll and injury burden, the high severity of crashes involving trains makes it a key “safe system” focus. It is also alarming that the proportion of crashes involving pedestrians and cyclists at level crossings has been increasing over recent years. This in part is owing to the construction of several cycleways and shared paths that travel alongside railway lines. In the past, KiwiRail has relied primarily on the Australian Level Crossing Assessment Model (ALCAM), a crash estimation model, to assess the increased risk of crashes at crossings resulting from a change in use. Although ALCAM is one of the better developed level crossing models internationally, it does have its limitations when used in isolation. ALCAM documentation specifies that other information such as incident data and the opinions of locomotive engineers should be considered in assessing risk. In practice, these factors and ALCAM risk ratings are rarely afforded equal importance. ALCAM does not pick up in sufficient detail the safety impacts created by the surrounding transport network. To better inform decision making, KiwiRail has developed a wider assessment process that includes these factors: the Level Crossing Safety Impact Assessment (LCSIA). This paper outlines the LCSIA process, provides an example of how it has been used, and also discusses the important learnings that have occurred since it was first introduced in 2016.

尽管与全国道路通行费和伤害负担相比，新西兰平交道口的伤亡人数相对较低，但火车相撞的严重程度使其成为重点关注的“安全系统”。令人震惊的是，近年来，在平交路口，涉及行人和骑自行车的人的撞车比例一直在增加。部分原因是由于修建了数条自行车道和沿铁路线行驶的共享路径。过去，KiwiRail主要依靠澳大利亚平交道口评估模型（ALCAM）（一种碰撞估计模型）来评估由于用途变更而导致的十字路口发生撞车的风险增加。尽管ALCAM是国际上开发最完善的平交道口模型之一，但在单独使用时确实有其局限性。ALCAM文档规定在评估风险时应考虑其他信息，例如事故数据和机车工程师的意见。在实践中，这些因素和ALCAM风险等级很少被给予同等的重视。ALCAM没有足够详细地了解周围交通网络所产生的安全影响。为了更好地为决策​​提供依据，KiwiRail开发了一个更广泛的评估流程，其中包括以下因素：平交道口安全影响评估（LCSIA）。本文概述了LCSIA流程，提供了如何使用它的示例，还讨论了自2016年首次引入以来所发生的重要学习。这些因素和ALCAM风险等级很少被给予同等的重视。ALCAM没有足够详细地了解周围交通网络所产生的安全影响。为了更好地为决策​​提供依据，KiwiRail开发了一个更广泛的评估流程，其中包括以下因素：平交道口安全影响评估（LCSIA）。本文概述了LCSIA流程，提供了如何使用它的示例，还讨论了自2016年首次引入以来所发生的重要学习。这些因素和ALCAM风险等级很少被给予同等的重视。ALCAM没有足够详细地了解周围交通网络所产生的安全影响。为了更好地为决策​​提供依据，KiwiRail开发了更广泛的评估流程，其中包括以下因素：平交道口安全影响评估（LCSIA）。本文概述了LCSIA流程，提供了如何使用它的示例，还讨论了自2016年首次引入以来所发生的重要学习。平交道口安全影响评估（LCSIA）。本文概述了LCSIA流程，提供了如何使用它的示例，还讨论了自2016年首次引入以来所发生的重要学习。平交道口安全影响评估（LCSIA）。本文概述了LCSIA流程，提供了如何使用它的示例，还讨论了自2016年首次引入以来所发生的重要学习。
