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 5 The crash rate on a heavily-traveled two-lane rural highway is abnormally high. The corridor is 14 miles long with an AADT of 34,000. An investigation has determined that head-on collisions are most common, with an RMVMT of 4.5, and are caused by vehicles attempting to pass. Addition of a passing lane has been observed as an appropriate countermeasure with a CMF of 0.65. Calculate the estimated yearly reduction in total crashes.
7. The following are the tabulation of the coverage count of the average daily traffic on a monthly and weekly basis made with automatic traffic counts on a highway. Use the tables to calculate;(a) the ADT for February and October based on 2 days counts: (i) on Tuesday in February the daily counts were 250 vehicles and (ii) on Friday in October, the daily traffic volume was 300 vehicles. (b) the AADT if the flows counted on Friday, Saturday and Sunday in July were 8000, 6000 and 5000 vehicles on a 16 hourly count basis.(c) the seven day 16 hourly flow in September.

QUESTION 9 The adjustment for the access point density is based on empirical studies indicating that for each access point per mile, the estimated FFS decreases by 0.25 mi/h, regardless of the type of median. Note that these access points are those that influence traffic flow and that access points that go unnoticed by drivers are not included in the calculation of the access point density. Therefore, what is the expected reduction (mph) in FFS when the access density is 4 access points per mile. (enter a positive value)
Civil Engineering The number of accidents has been recorded at an intersection in the last three years as follows: 18, 21, and 19. The accidents were mostly due to left-turning vehicles, speeding, and the absence of left-turn protection. The average ADT for the last 3 years is 8500. The following shows the crash reduction factor for various countermeasures: Reduction Factor Countermeasure Retime signals Provide left-turn signal phase Reduce speed limit on approaches Provide turning guide lines Prohibit left turns 0.10 0.30 0.35 0.05 |0.75 a) Determine the appropriate countermeasures b) Determine the expected reduction in crashes if the countermeasures are implemented. The ADT is expected to increase 2% Neat work please
