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 12,00

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 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 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.
An urban arterial street segment 0.2 km long has an average annual daily traffic (AADT) of 15,400 veh/day. In a three-year period, there have been 8 crashes resulting in death and/or injuries and 15 involving property damage only. The statewide average crash experience for similar types of roadway is 375 per 100 mv-km for a three-year period of which 120 involved death and/or injury and 255 caused property damage only. Is the 0.2 km long street segment hazardous? In identifying hazardous locations, consider that a single death/injury crash is equivalent to three property damage crashes. Use a 95% confidence level.

Traffic flow on a three-lane (one direction) freeway can be described by the Greenshields model. One lane of the three lanes on a section of this freeway will have to be closed to undertake an emergency bridge repair that is expected to take 2 hours. It is estimated that the capacity at the work zone will be reduced by 35 percent of that of the section just upstream of the work zone. The mean free flow speed of the highway is 50 mi/h and the jam density is 115 veh/mi/In. If it is estimated that the demand flow on the highway during the emergency repairs is 85 percent of the capacity, using the deterministic approach, determine the following. (a) the maximum queue length (in veh) that will be formed Your response differs from the correct answer by more than 10%. Double check your calculations. veh (b) the total delay (in h) h (c) the number of vehicles that will be affected by the incident veh (d) the average individual delay (in min) min
A traffic engineer at the City of Wahoo Land wants to determine a proper storage capacity for an on-ramp. It was found that a mainline (single lane) and on-ramp traffic arrivals follow Poisson distribution with a mean of 800 passenger vehicles per hour and 150 passenger vehicles per hour, respectively. Assume critical gap is 4.5 seconds for merging vehicles. Determine appropriate storage capacity as a number of vehicles that would prevent any spill over at 95% confidence interval.
