Visualizing the Hot Spots of Adverse Weather Induced Traffic Accidents in Bangladesh

Weather conditions, a phenomenon showing distinct geographic patterns, is one of the key contributors to roadway traffic accidents. This paper aims to investigate the relationship between weather conditions and road accidents in Bangladesh and gives a comprehensive overview of the spatial distribution of road accidents in Bangladesh in correlation to adverse weather and the most likely contributors of adverse weather (precipitation, topological elevation, etc.). For analysis, traffic accident data of Bangladesh for the period 2010 to 2015 were obtained using MAAP (Micro-computer Accident Analysis Package). Among recorded 11,268 accidents of the six-year period, 3.52% and 2.05% accidents took place during rainy and foggy weather respectively. These accidents had a significantly higher fatality rate accounting for 81.5% and 83.12% for rainy and foggy weather respectively. This study also shows the month-wise accident severity trend for adverse weathers for the period of 2010-2015. For spatial distribution of road accidents, hotspot analysis was done to identify the geographic locations (districts) statistically more vulnerable to adverse weather effects using Getis-Ord Gi*(d) Statistic of ArcGIS. The findings of the study will be helpful in the implementation of effective countermeasures for preventing weather-related road accidents with optimum adeptness.
