Need type answer 1.A highway section has an accident rate of 150 accidents per 100 mvk. If the mean accident rate for all sections is 55 per 100 mvk, and the standard deviation is 26 per 100 mvk,should the section under study be flagged as hazardous with 90 percent confidence? 2. A stretch of four-lane, two-way highway 5.0 km long has a traffic volume of 25,000 vehicles per day. If for the last three years, the total number of accidents recorded was 1,800, determine the accident rate per 99 mvk.
Need type answer a. A section of road has 55 accidents recorded in three years. For the same period, the estimated vehicle travel on the section was 23 mvk. Considering only those sections having the same characteristics as the section under study, the mean rate is 80 accidents per 100 mvk. Is the section hazardous with 90 percent level of confidence? b. Based on the graph of the accidents time per day on ‘explain’, what time makes up the most number of accidents? Discuss and explain why the frequency of accident is high.
A 1.5-mile section of a two-lane road has an AADT of 10,000. In a three-year period, there have been 6 fatal accidents and 12 non-fatal accidents. The state allows 350 accidents per 100 mvm for three years, of which 100 are fatal. For which value of confidence level, this highway is considered safe? If the following countermeasures are implemented: widening the existing lane by 2 feet, and widening the existing shoulder by 2 feet paved, and widening the clear zone by 5 feet, what will be the number of accidents reduced if the AADT became 12,000?
