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.

The average number of collisions on Rt. 116 in South Deerfield is 15 per year. To address the high crash rate, a signal has been installed to make right-of-way explicit. The number of accidents in the following year was 9. MassDOT desires to know with how much confidence this reduction of accidents can be attributed to anything other than random chance.
1) 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: Countermeasure Reduction Factor Retime signals Provide left-turn signal phase Reduce speed limit on approaches Provide turning guide lines 0.30 0.30 0.35 0.05 a) Determine the appropriate countermeasures b) Determine the expected reduction in crashes if the countermeasures are implemented. The ADT is expected to increase 2%

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.

An expressway consists of four lanes, where the capacity per lane is 2500 vehicles. In normal days, 6500 vehicles pass. However, there is an emergency road repair conducted in which two lanes will be closed. The repair lasted 150 minutes. Calculate the maximum queue length, total length, and number of vehicles impacted by the event, and average individual delay.
