Abstract
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.
