西澳大利亚州经济的最新发展，包括广泛的交通拥堵以及道路安全问题日益突出。以前的研究依靠传统的统计方法来调查机动车碰撞的模式和特征。虽然统计分析很有用，但它本身无法提供空间背景，因此无法将现有的碰撞特征与空间分布联系起来。目的通过空间分析方法，确定2001-2013年间西澳铰接式重型车辆碰撞的集中或“热点”。方法利用综合道路信息系统（IRIS），采用空间建模和新兴热点等时空分析方法识别西澳大利亚州特定道路上的新兴热点。结果结果表明，大部分铰接式重型车辆碰撞发生在珀斯市区附近或市区内。基于时空趋势分析，我们的发现突出了一些正在成为感兴趣领域的地区。本研究是采用空间分析方法研究西澳大利亚州重型车辆碰撞的首次尝试之一。将空间方法应用于道路安全数据有可能获得以前未被发现的见解，这些见解可以进一步扩展，并为该领域的未来研究提供途径。
BackgroundRecent developments in Western Australia's economy including widespread traffic congestion as well as road safety issues are increasingly becoming prominent. Previous studies relied on traditional statistical methods to investigate patterns and characteristics of motor vehicle crashes. Although useful, statistical analysis alone is incapable of providing a spatial context and is therefore unable to associate existing crash characteristics with a spatial distribution.AimsTo identify concentrations or “hotspots” of articulated heavy vehicle crashes in WA between the years 2001–2013, by using a spatial analysis approach.MethodsSpatial modelling and spatio-temporal analytical methods such as Emerging Hotspots were used to identify emerging hotspots on specific roads in Western Australia using the Integrated Road Information System (IRIS).ResultsThe results suggest that the majority of articulated heavy vehicles crashes occurred in the vicinity or within the Perth metropolitan area. Based on spatial-temporal trend analyses, our findings highlight some regions that are emerging as areas of interest.DiscussionThis study was one of the first attempts to adopt a spatial analysis approach in studying heavy-vehicle crashes in Western Australia. Applying spatial methodologies to road safety data has the potential of obtaining previously undiscovered insights, which can be extended further, and provide future avenues to research in this field.
