The DSWD is debating if the are going to provide a recovery car on a highwat to help clear the incidents as fast as posible. The Highway carries Five thousand vehicles during the rush hour. Traffic records show that on average,the number of incidents during moring rush hour is 5. The DSWD rejects any provisionfor vehicle on the road if the probabilityof having more than 5 incidents in any one morning is lessthan 30 percent. Does DSWD needs to provide the recovery car?

A rural primary road segment of 2 miles long has an average annual daily traffic(AADT) of 11,350. The number of crashes that have occurred over the past 5 yearsare 5 fatal, 55 injury crashes and 100 property damage only crashes. Statewide averagecrashes for this type of road are 2 fatal, 130 injury, and 300 property damage onlycrashes per 100 MVMT. The weighting factors for fatal, injury and property crashesare 8, 3, 1, respectively. Using the critical crash ratio methodology, determine whetherthis site can be labeled a hazardous site. Use a 95 percent confidence limit.

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.
The accident rate for 100 million vehicle miles of travel is 9.8. The length of the road is 15 mileswith an ADT of 67,000. Determine the estimated yearly reduction in total crashes if the crashreduction factor is one third.
A municipal council on transportation is taking into account whether to base a recovery vehicle on a stretch of an highway to help clear incidents as fast a possible. The highway concerned carries over 5000 vehicles during the peak rush hour period. Traffic records show that on average, the number of incidents during the AM rush hour is 5. The council rejects any provision for a vehicle on the road if the probability of having more than 5 incidents in any one morning is less than 30%. Based on this information, should the council provide a vehicle?

A state transportation agency want to evaluate engineering countermeasures applied to a two-lane,two-way rural highway segment.This 4 miles segment has been identified as having 14,19,and 23 total crashes in the last three years,before the implementation of the countermeasures.The AADT at the segment for last three years is 5630 vehicles per day and the AADT for after implementation is 6240 vehicles per day.Compute the expected average crash frequency for the after period, assuming the treatment was not implemented.The segment has the same conditions as the base conditions established for SPF.
