Highway Safety

Proper highway safety refers to the methods or rules that prevent highway travelers from being killed or severely injured. Proper highway safety measures help to protect motorists, cyclists, pedestrians, passengers on public transport, and so on.

Question

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.

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?
Problem 25: The number of accidents for 4 years recorded in a certain section of a highway is 4,892. If the average daily traffic is 438, determine the accident rate per million entering vehicles.
The relationship between flow and density on a four-lane highway (two lanes per direction) is known to follow GreenShiled's model, with a free flow speed of 100 km/h and a jam density of 80 veh/km/lane. One of the two lanes of the EB direction will be closed for an entire month for maintenance. The traffic demand for the highway on a typical weekday is shown in the table below. a) What is the maximum length of the queue upstream of the bottleneck during both the morning and afternoon peak hours? b) At what time will the morning and afternoon queues be dissipated? c) Draw the shock wave diagram (for the entire day) showing shock wave speeds, critical times, and distances. Time 7:00 AM - 9:00 AM 9:00 AM 3:00 PM 3:00 PM 7:00 PM 7:00 PM–11:00 PM 11:00 PM 7:00 AM Average Demand (vph) 3000 1500 3200 1200 400
A proposed improvement will widen a two-lane rural highway from 9-ft-wide (per lane) to 11-ft-wide (per lane) if the highway has an AADT of 2100 veh/day. If there are an average of 25 crashes per year on the segment proposed for improvement, and 67% of the crashes are of the type targeted by the improvement, estimate the expected number of crashes (per year) after the improvement is constructed.
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.
