Abstract
The mission of reducing the number and severity of traffic accidents becomes the dominant target of road traffic safety management worldwide. The main objective of this work is to analyze traffic accidents in temporal and spatial frameworks in the capital city Amman and identify hotspot zones in the study area. Several statistical analyses are conducted using SQL to give insight into the temporal distribution of accidents and to identify the most revealing accidents based on several attributes such as the year of accidents, the severity of accidents, road type, and lighting environment which enables the authors to do further investigations on the more frequent accidents. GIS-based statistical and spatial analysis tools are utilized to examine the spatial pattern of accident distribution in the study area for three successive years, hotspots are identified for clusters of high concentrations. The Nearest Neighbor Index (NNI) is used to analyze the pattern of traffic accident distribution based on selective parameters. This was followed by identifying hotspot zones for regions that showed clustering using the optimal hotspot analysis tool. Experimental results showed clustering for all tested groups, and thus hotspots were detected for these accidents in the study area. The importance of this work is in providing a spatial understanding of accident distribution in the capital city of Amman which can help policymakers of road safety setting out efficient strategies for traffic safety management and find optimal solutions as required for factors causing such accidents.
Highlights
Traffic accident problem is major public health anxiety in the globe
It is estimated that the cost of these accidents is about 518 billion USD worldwide [1, 2]. In developing countries such as the Kingdom of Jordan, people are more vulnerable to road accidents according to the global status report issued by the World Health Organization(WHO) on road safety
This paper presents a statistical analysis of traffic accidents in the city of Amman, Jordan for three successive years 2017,2018, and 2019 based on different attributes such as severity, type of location where accidents have occurred, lighting environment of accidents’ locations
Summary
Traffic accident problem is major public health anxiety in the globe. Statistics showed that there are about 1.3 million deaths and 50 million injuries caused by road accidents each year [1].The traffic authorities in most countries tend to control the traffic to reduce traffic accidents using several techniques such as: optimize traffic-light management, improve cycling infrastructure, enforce existing road traffic laws, improve perceptions of buses, extend residents' parking zones, use CCTV to monitor road conditions, charge for workplace parking, improve bus services, .etc.The impact of road accidents on both economy and society is massive. Statistics showed that there are about 1.3 million deaths and 50 million injuries caused by road accidents each year [1]. It is estimated that the cost of these accidents is about 518 billion USD worldwide [1, 2]. In developing countries such as the Kingdom of Jordan, people are more vulnerable to road accidents according to the global status report issued by the World Health Organization(WHO) on road safety [3], Jordan has appeared in the set of the worst countries regarding road safety. The report revealed that the rate of deaths caused by road accidents is about 24.4 for each 100.000 of population
