Identifying the (Hot Spots) for traffic accidents in Erbil City
A study of the problems of the Urban Environment

Abstract
Urbanization brings many problems to the urban environment, such as: problems of the urban transportation,
represented in traffic accidents which has become the issue of the era and threatens humanity according to the
World Health Organization reports, it has become the main concern of all government agencies due to its impact
at both the economic and social levels. Based of this, this research aims at monitoring the traffic accident
locations in Erbil city and identify the hot spots in which the number and intensity of accidents are high, the
pattern of their distribution, and to know the special and temporal characteristics of these accidents, and the
reasons of their occurrence, for the purpose of constructing an accurate database and propose sound scientific
methodologies to the relevant authorities and decision makers for addressing the issue that are based on the
descriptive method and statistical spatial analysis, in order to achieve traffic safety to serve the citizens of the
city. The research included three main axis, in addition to the introduction, the first axis began by identifying the
most important spatial and temporal characteristics of the traffic accidents in the study area, the second axis was
dedicated to study the factors that influence the occurrence of the accidents, where the third axis discussed the
spatial modelling mechanism to identify the traffic accidents hot spots in the study area using a Geographical
Information System. The research concluded with a set of conclusions and recommendations.
Key words: Urban Environment Problems, Traffic Accidents, Erbil City, Hot Spots

Road traffic accidents (RTAs) and its associated injuries are one of the major causes of death in developing countries. Some researchers blame illiteracy especially among commercial drivers while others mention the poor nature of the road as the cause of this menace. In recent years, road traffic accidents in Ghana have become a major social problem in the world as one writer put it “carriage without horses shall go and accident fill the world with woe”. The main objective of this study is to analyze the pattern of road traffic accidents in the Cape Coast Metropolis. Non-spatial/secondary data collection was used to obtain information on the location, the vehicle type, casualties, time and causes of the road accidents. One common feature is to assess information on RTAs. This study is therefore committed to explore issues surrounding road traffic accidents in Ghana with much emphasis on the Cape Coast Metropolitan area using Geographic Information System (GIS). Secondary data was used in obtaining the sample data. Data was collected directly from the record books of the MTTU in Cape Coast, a branch of the Ghana Police Service. Data was analyzed and interpreted with the aid of SPSS v. 21 and Arc GIS 10.3 versions. After the analysis, the study revealed that, 9 hotspots locations which were identified were comparatively competitive to each order. On a scale, the highest of all the hotspot intensity is Pedu Junction which recorded 33 cases followed by UCC East Gate which is responsible for about 30 counts. Morree Junction together with Nkanfoa/Third Ridge Junction recorded the same counts which are 22 each while Yamoransa Junction, Kotokuraba and Siwdu accounted for 21, 20 and 18 respectively. Kingsway and Abura recorded 15 occurrences each on a range. Finally, it was found out that most of the vehicles involved in road traffic accidents were private vehicles which numbered up to 232 cars making a share of (50.5%) out of the total of 459 vehicles. Hotspot locations and road traffic accident fatalities were mapped using GIS ArcMap/View.

In the recent years the number and speed of vehicles have been increased and the quality of roads and safety standard of vehicles are being optimized to a desired level by using various methods. In addition, the road users are being educated to improve their behaviour in terms of safe driving. This study has shown how to reduce the traffic accidents on selected stretches in urban context. The goal of this paper is to analyze traffic accidents in selected stretches i.e. Miyapur to kukatpally, Dilsuknagar to Chaderghat, RTC X-road to Secunderabad, Afzalgunj to Puranapul, which are affected due to traffic congestion using GIS in the City of Hyderabad. The first part of the study investigated identification of maximum number of accidents in selected areas, accident victim wise, accident accused vehicle wise, accident day wise, accident by age wise, accident by hour wise, accident by drunk and drive wise etc. The second part of the study investigated collection of spatial data and non spatial data for identification of traffic accident black spots. The third part of the study investigated the development of spatial and attribute database to minimize the traffic congestion and to suggest the alternate route to prevent accidents. The last part of the study investigated the development of processing tool to create black spot analysis by Kernel Density Estimation method using GIS to reduce traffic accidents. The study suggested several improvements that can be implemented in order to have a more user-friendly and automated system and to make data accessibly for all the road users and to implement various procedures to provide more safety on roads.

A significant unexpected outcome of transportation systems is road accidents with injuries and loss of lives. In recent years, the number of studies about the tools for analysing accidents and road design has increased considerably. Among these tools, Geographical Information Systems (GIS) stand out for their ability to perform complex spatial analyses. However, sometimes the GIS, has been used only as a geographical database to store and represent data about accidents and road characteristics. It has also been used to represent the results of statistical studies of accidents but, these statistical studies have not been carried out with GIS. Owing to its integrated statistical-analysis capabilities GIS provides several advantages. First, it allows a more careful and accurate data selection, screening and reduction. Also, it allows a spatial analysis of the results in pre and post-processing. Second, GIS allows the development of spatial statistics that rely on geographically-referenced data. In this paper, several GIS tools used to model accidents have been examined. The understanding of these tools will help the analyst to make a better decision about which tool could be applied in each particular condition and context.

India's share of road accident in the world is an area of serious concern. With advancement in technology, new and sophisticated models of vehicle are available and their numbers are increasing day by day. A traffic accident has multi-facet characteristics associated with it. For proper traffic accident analysis use of GIS technology has become an inevitable tool. The city of Dehradun, the capital of Uttaranchal in northern part of India has been selected for study. Five years of police records reveal that nearly 72% of accidents lead to fatal and grievous injuries. Cars, jeeps and vans are mostly responsible for accidents and that the occurrence of accidents is mostly concentrated between 2PM to 10PM. The study reveals that a proper traffic management is required for the city to check the growth of traffic accidents.
