Abstract
Now days road safety becomes a worldwide concern. Similarly Road safety risk has been a major issue in the study area (Metu- Yayo road segment). The successful assessments of road safety inspection within the study area are very essential to minimize future road accidents faced by the entire road user. The study were started by examining the current condition of the road using road safety inspection manual then it used focus group judgments and it is analyzed by analytical hierarchical process method based pairwise comparison in identification of contributing factors for the road safety risk using two levels of Analytical Hierarchical process, and four major factors i.e. pavement surface condition, road geometry condition, road side environment condition, road traffic control condition, and also it tries to prioritize the road section to identify the road with better facilities and the road in the worst condition. During road safety inspection in the study area the road experience early stages of pavement distresses, road traffic sign related problems, sight distance obstruction, and soil slide related problems this in turn speeds up the road safety risk and increases the occurrence of road traffic accidents. As a result, this study concluded, road traffic control factors were the most significant factors which contributes to the occurrences of road safety risk. In comparison, Lakosaya to Yayo road section is the found in a better condition, but the road section from Mechi to Lakosaya is found in worse condition in the study area.
Highlights
IntroductionIn undeveloped countries with 1% of registered vehicles there is 16% of road traffic deaths were recorded but the rest of 74% road traffic deaths happened in middle-income countries
All over the world road traffic accident is a challenging problem
From the priority vector value shown in the above figure7 (b) the road traffic control factors accounts around 54% for the road risk when it is compared to the other factors, it is the most significant factor which contributes high road safety risk at Mechi to Lakosaya road; road side environment condition (18%) road surface condition (16.9%), and road geometry (9.5%) followed respectively. the road from Mechi town to the small village Lakosaya is more or less vulnerable to road safety risk due to traffic control facilities condition factors which covers 47%, but the road side environmental condition and geometry of the road factors share the same value 18.8%, and the road surface condition factors cover 15.4% which has less effect on the road safety risk
Summary
In undeveloped countries with 1% of registered vehicles there is 16% of road traffic deaths were recorded but the rest of 74% road traffic deaths happened in middle-income countries. As recent research study reveals that around 34% of crashes were recorded in urban area due to road way condition factors. To alleviate this problem the road safety reactive approach method of safety improvement interventions were taken after the road is already vulnerable to road accidents. Many countries exercise reactive approach method based as road safety prevention tool but fails to improve their road safety problem due to the need to have required written standard approach. Other proactive approach intervention is needed i.e. proactive Road Safety Inspection (RSI) for developing countries which is the new method to encounter road safety problem before road
