1. Problem Definition
Oman is a developing country and infrastructural projects are increasing sharply. One of the main projects in Oman are the roads , unfortunately Oman is suffering from road accidents as the statistics for 2012 shows that one case of injury every hour due to road accidents and one death was reported every eight hours due to a crash. In this blog we need to identify the locations in which the most accidents happen so that more road resolutions to be exerted.
2. Identify the Feasible Alternative
Table 1 is showing statistical road accidents in Oman according to historical data form 2012.
Assuming that these accidents are due to road defects, 80/20 rule will be used here to find the 20% road defects that cause 80% road accidents
3. Development of the Outcome for Alternative
Pareto chart will be applied here to find out which location need first attention. Pareto chart contains both bars and line graph in which values are plotted in descending order of relative frequency from left to right.
Table 2. Locations that leading to majority of road accidents
4. Selection Criteria
20% of road Locations which if tackled will reduce 80% of the problems.
5. Analysis and Comparison of the Alternative
Figure 1. Pareto chart analysis
Figure 1 shows that maximum accidents are in Mascat where as minimum accidents are in Musandam
6. Selection of the Preferred Alternative
According to figure 1, the Government should focus only on 20 % of road locations which cause 80% of accidents in this case it is Muscat area (34%):
7. Performance Monitoring and the Post Evaluation of Result
The government to start improving the roads in Muscat and to apply the same method every sex month so that new locations can be tackled.
