Comparative Study of Traffic Safety and Geometric Design of Roads in Khartoum and Abu Dhabi

Abstract

Geometric design plays an important role in increasing the traffic safety on roads. In order to be the case, there must be certain characteristics available and this what the study has been discussing mainly, with a comparison that doing in the United Arab Emirates with the alarm on the role of good management of the traffic to reduce traffic accidents . In the design phase of the roads we find that it is very important to establish harmony between the human element , element of geometric design and traffic management. In spite of that the human factor, including the driver , the passenger and the pedestrian, has a prominent role in the occurrence of traffic accidents on the road or may be a combination of factors involved in the occurrence of accidents . However, to control the roads factor is much easier than the human factor and that, by making good geometric design, to compensate for other factors. This makes it clear that in order to establish the safety of the road, it is important to increase attention to the geometric design and limited particular specification of any road . The aim of this study is to formulate the initial principles of the Sudanese specifications roads. , work on developing specifications for traffic management and alert to the importance of traffic signs and the impact of their absence in the occurrence of traffic accidents. In this study, the first chapter form introduction provided for this study , reviewed the objectives of the study , the study area , methods of collecting information for the study and difficulties of this study Chapter form the theoretical basis for this study by reviewing the factors influencing the geometric design and safety-related traffic and the types of roads and subdivisions. Study was carried out by taking the elements of geometric design on the roads and properties in mind, accidents that have occurred in the roads and we are given explanations on how to make good safe geometric design. We were clarify the possible causes of occurrence of accidents and ways to address engineering and how to conduct engineering analysis of the incident and this is discuss in chapter third.. Its has been clear that there is the impact of traffic management on the occurrence of the accident as the existence of traffic signs as the existence of the optical reflector and this is set forth in Chapter IV. We make recommendations as necessary to the work in specifications of the roads in Sudan and to conduct engineering analysis of accidents and to propose future research as Inquiry specifications of the roads in Sudan and this is what has been discussed in Chapter Five.
