ANALYSIS ON TRAFFIC SAFETY AND ROAD ACCIDENTS: A CASE STUDY ON SELECTED ROADS IN MUSCAT, OMAN
Highway safety is of serious concern not only to the Highway Authorities but also to the whole Nation, as they involve in loss of property and human life. Increase in vehicular growth and there by the traffic on Muscat roads is of serious concern. Even though the accidents growth rate is declaiming over the last ten years, but the number of accidents is of serious concern to the Authorities. The reasons for accidents are many folds and among them, high speeding of vehicles is the major factor contributing to the accidents. This study aimed at conducting an investigation to understand the causes of accidents for improving highway safety in Muscat. The methodology involved is discussions with the Authorities elicit the opinion of Royal Oman Police (ROP) and collection of data from ROP and field road inventory data. Also operating speeds of the vehicles during peak and non-peak hours are collected on the selected roads to validate the hypothesis. Data collected from primary and secondary sources, analysis of vehicular speed data and accident statistical data facilitated to draw conclusions for the traffic safety concerns.

Traffic accidents have serious public health and economic concern all over the world especially in developing countries. Oman had registered as the highest road accident death rate in the GCC and third highest in the Eastern Mediterranean region. The analysis of accident characteristics is one of the most significant aspects that engineers rely on during the design of road networks and/or the safety performance evaluation of roadway systems. The main objective of this paper is to perform several statistical analyses for traffic accidents characteristic at the road network in Dhofar, Sultanate of Oman. Such analyses will help to explore the scale and main characteristics of traffic accidents for specific network system or location as well as identifying the hazardous locations and the most important variables that may be considered in building Accident Prediction Models (APMs).In this study a new methodology for recording and analyzing accidents data was established. Different types of accident and accidents" causes were defined and analyzed in this study. Total of 5825 accidents was collected from Royal Oman Police (ROP) during 2007 to 2010. Statistical analysis was carried out using accident frequencies and accident rates. The results showed that "Collision between vehicles" has the highest ratio among the accident with 58% followed by "crashing with stationary" with 21%. Approximately 47% of total accidents occur at intersections, 90% of them occurred at un-signalized intersections (roundabout and T-intersections). About 68% of fatal accidents occur at road links. The sideswipe accidents have the highest ratio among accident types. The accident rates for roundabouts (0.61 accidents per million entering vehicles) are higher than the T-intersection rates (0.48 accidents per million entering vehicles). It seems that traffic volume and drivers" characteristics, road network types, weather and time were the major factors affecting the number of accidents. The results of the study may have significant consideration for transportation and road safety planning in Sultanate of Oman and other countries in the Middle East area, especially Gulf countries with similar conditions.
Evaluation of Traffic Accidents Rates in Al-Diwaniya City
Journal of Babylon University, 2015
Although the enhancing of traffic safety is the main concern of the local highways agencies, traffic accidents have been increased rapidly in recent decades mainly due to sharp increase in vehicles using road networks. In order to limit such increase, the causes of accidents should be analyzed properly so as to consider proper solutions. This paper uses real data taken from the local traffic agency in Al-Diwaniya city for the period from 2004 to 2013 to indentify the frequency and causes of traffic accidents.Questionnaire technique has also used in this study to show the percentage of unrecorded accidents. The results showed that the average deaths in the city caused by traffic accidents was found to be 33 deaths per 100000 population which is much higher than the world’s average death rates of 18 deaths per 100000 population. It is found that more than 50% of traffic accidents are related to drivers’ errors while the faults which may happen for vehicles are representing about 24%. ...

The final sections of main access roads to the cities require especial attention as the frequency of accidents in these road sections are considerably higher than other parts of interurban roads. These road sections operate as an interface between the rural roads and urban streets. The previous researches available on this subject are limited and they have also mainly focused on a narrow range of factors contributing to the accidents in these areas. The main contribution of this research is to consider a relatively comprehensive range of potential factors , and to examine their impacts through the development and comparison of both conventional probabilistic models and Artificial Neural Network (ANN) models. For this purpose, information related to the main access roads of three major Iranian cities were collected. This information consisted of accident frequency data together with the field observations of traffic characteristics, road-way conditions and roadside features of these ...

Developing nations including Pakistan are faced with new dimension of highway safety challenges after the advent of motorways, safety management of motorways demand more meticulous addressal of safety issues due to involvement of high speed dynamics. This Study presents a method by which the accident-prone locations on roads, commonly termed as accident blackspots, can be identified. Motorway (M-2) connecting Lahore to Islamabad, one of the major motorways of Pakistan has been selected for study. The reasons for the accidents can be attributed to the lack of driving skill, lack of education, economic values, lack of signage, geometric design problems and improper design of pedestrian crossing. There are however, other factors, which contribute directly or indirectly to the accidents include road, vehicle, road user and environmental factors. After analysis it was found that, accidents are majorly caused by careless driving (25%), dozing at wheel (23%), tyre burst (18%), brake failure (9%) and pedestrian crossing (6%). Proper traffic guidance and control system to guide road users ensuring safe movement of vehicles has been recommended and some of the low cost facilities such as pedestrian crossings underpasses near Lahore, dozing alert alarm to minimize dozing, tyre checking gauges to counter tyre burst, training to avoid brake failure, and advertisement through print and electronic media to increase awareness have also been proposed in order to improve the safety of the road and minimize the accidents.
Journal of Occupational Health and Epidemiology
Article Info Background: Several factors influence the growth in the number of road traffic accidents and the resulting death rate. Road accident scenarios can be considered in different seasons and time intervals. In the present study, the role of factors effective in the growth of the number of accidents was explored in the south of Kerman during the period from 2013 to 2017. Materials and Methods: In this cross-sectional study, the data were collected from the Traffic Police Unit's database in the south of Kerman during the period from 2013 to 2017. The data obtained included the time of the day, roads of accidents, numbers of fatal accidents, and years of occurrence. The data were analysed using the logistic regression. Results: After examining the role of various factors in fatal road traffic accidents, it became clear that the chances of death were higher in road accidents on main roads (OR = 1.30; 95%CI=1.02-1.70; p=0.037) than on rural roads. In terms of the seasons of occurrence, death rates were higher in autumn (OR= 1.30; 95%CI=1.02-1.80; p=0.027) than in winter. From among the effective factors, overspeed (OR= 1.90; 95%CI=1.40-2.50; p<0.001) and deviation to the left lane (OR = 2.20; 95% CI = 1.70-2.90; p-value<0.001) were more likely to lead to death than drowsiness and inattention to the front. Conclusion: The results showed that overspeed, deviation to the left lane, as well as accidents on main roads, and in autumn resulted in an increase in the mortality rate. The severity of road accidents would probably decrease in the region by paying more attention to main roads especially in autumn and training drivers.
Analysis of Accident Data and Evaluation of Leading Causes for Traffic Accidents in Jordan
Jordan Journal of Civil Engineering, 2010
Road safety is a primary concern and goal of highway and traffic engineers worldwide. The road network in Jordan exhibits relatively high traffic volumes, particularly in urban areas and in the Central Business District (CBD) areas of major cities. Jordan ranks one of the top countries worldwide in terms of having higher numbers of road traffic accidents leading to a relatively high number of fatalities and injuries. In the past few years in particular, the number of registered vehicles in Jordan has considerably increased. As a result, traffic volumes and Vehicle Miles of Travel (VMT) have significantly increased leading to deteriorating traffic flows and escalating traffic congestions and jams. Consequently, the number of road traffic accidents has also noticeably increased in Jordan in the past decade. Complete analysis of statistical data obtained for traffic accidents in Jordan was conducted in this study. Evaluation of the possible leading causes of traffic accidents in Jordan was also carried out. Different possible causes along with behaviors of drivers and pedestrians were investigated and correlated with the number of traffic accidents, fatalities and injuries. Jordan was found to have accident, fatality and injury rates that are considerably higher than those of other countries in the world. Nonetheless, as rates with time, the fatality and injury rates seemed to be moving in the right direction. Yet, the number of traffic accidents, fatalities and injuries looked critical. Traffic accidents and casualties were observed to be higher in summer times. More than 90 percent of traffic accidents, fatalities and injuries occurred on roads with speed limits between 40 and 60 km/h. Pedestrians composed the highest percentage of the total numbers of fatalities and injuries. The majority of driver casualties and passenger casualties (fatalities and injuries) belonged to the age group of 18-42 years. On the other hand, the highest percentage of pedestrian casualties belonged to the age group of 0-18 years. However, about 80 percent of the casualties in Jordan were males and only 20 percent were females. "Tailgating" and "not taking safety measurements during driving" were the most two important driver behaviors in terms of traffic accidents. Yet, behaviors of "using wrong lane" and "not taking safety measurements during driving" led to the highest percentages of the total number of fatalities and injuries. The majority of the pedestrian fatalities and injuries were in fact walking on road during the time of the accident occurrence and about one third of them were walking on sidewalk. Other behaviors of drivers and pedestrians were also important and created traffic complexity and hazardous situations leading to a reduction in saturation flow rates and in capacities and causing bottleneck conditions and traffic jams; hence resulting in traffic safety concerns.
Analysis of Road Traffic Accidents on Cairo–Suez Highway in Egypt
Scientific Journal of October 6 University, 2014
Transportation is the movement of people and goods from place to other, as a result of the interaction between different social and economical activities in several separate places. So, the main role of traffic engineering is to deal with planning, geometric design and traffic operations for road networks, terminals and lands lie on roads to achieve safe, fast and convenient transportation for people and goods. The main role of transportation for human`s life, leads to continuous increase in traffic volumes, which results continuous increase of road traffic accidents, environmental pollution and delays (because of traffic congestions). Increase of road traffic accidents is considered the most dangerous result of increased traffic volumes, as it cause many fatalities, injuries and damaged properties. So, it mainly and directly affects the situation of road traffic safety in Egypt, which became very dangerous during last few years. After collecting traffic data for Cairo-Suez Highway from the Traffic Police Department, Ministry of Interior in Egypt, this paper carries out quantitative statistical analysis of these data and finally, explores a linear regression model between the number of road traffic accidents and the types of vehicles caused these accidents. Data processing is mostly done by SPSS.

International Journal of Public Policy and Administration Research
The main objective of this study was to investigate the impact of factors linked to the geometric, roadway and traffic flow characteristics on traffic accident occurrence at Hazardous Road Locations (HRL) in the region of Sousse, Tunisia using longitudinal data of 52 HRLs for an 11-year monitoring period from January 1, 2004 to December 31, 2014. The results of estimation of Negative Binomial model and the Random Effects Negative Binomial model reported that the different variables representing the presence of rural segment, the curved alignment, the visibility, the average daily traffic volume, the presence of public lighting, the number of lane, the presence of vertical/horizontal sign, the presence of drainage system, the presence of paved shoulder, the roadway surface condition, and the presence of major road were the main significant variables influencing accident occurrences. Therefore, the results could be useful for deciders in the transport sector in order to implement effective measures to improve road safety by adopting proper sound use practices, establishing efficient transportation systems and formulating appropriate traffic policies and legislation. Contribution/Originality: This is one of the few studies which have investigated the occurrence of traffic accidents at Hazardous Road Locations in the region of Sousse (Tunisia) as a function of various explanatory factors linked to the geometric characteristics, roadway characteristics and traffic flow characteristics. 1443 persons were killed in 2016 and 11035 were injured in traffic-related crashes on the roads (National
