摘要

涉及油罐车的道路交通事故是尼日利亚伤亡的重要原因。这项研究考察了尼日利亚油轮事故的空间模式和可能的决定因素。2007年至2010年油罐车事故的次要数据和其他相关数据来自尼日利亚联邦道路安全委员会和国家统计局的数据库。油轮事故的空间模式是使用全球和当地Moran’s I统计数据绘制的。数据还采用了普通最小二乘法和地理加权回归法。调查结果表明，油轮事故因州而异，油轮事故的发生率也呈上升趋势。当地的Moran’s I表明，在整个研究期间，两个州的油轮事故持续聚集。确定了影响该国油轮事故模式的因素。该研究建议了在尼日利亚避免油轮事故的策略。

Understanding the spatial patterns of tanker accidents in Nigeria using geographically weighted regression

Road traffic accidents involving tankers are important causes of death and injury in Nigeria. This study examined spatial patterns and possible determinants of tanker accidents in Nigeria. Secondary data on tanker accidents for the year 2007 to 2010 and other relevant data were sourced from the databases of the Federal Road Safety Commissions of Nigeria and National Bureau of Statistics. The spatial patterns of tanker accidents were mapped using Global and local Moran's I statistics. The data were also subjected to Ordinary Least Square and Geographically Weighted Regression techniques. Findings indicated that tanker accidents vary by state and also revealed an upward trend in the occurrence of tanker accidents. The local Moran's I indicate persistent clustering of tanker accidents in two states throughout the study periods. Factors influencing the patterns of tanker accidents in the country were identified. The study recommends strategies for the avoidance of tanker accidents in Nigeria.

期刊介绍： The IJVS aims to provide a refereed and authoritative source of information in the field of vehicle safety design, research, and development. It serves applied scientists, engineers, policy makers and safety advocates with a platform to develop, promote, and coordinate the science, technology and practice of vehicle safety. IJVS also seeks to establish channels of communication between industry and academy, industry and government in the field of vehicle safety. IJVS is published quarterly. It covers the subjects of passive and active safety in road traffic as well as traffic related public health issues, from impact biomechanics to vehicle crashworthiness, and from crash avoidance to intelligent highway systems.
