Final answer:
4) All of the above, The correct answer is option which includes poor visibility, high traffic volume, and narrow roadways
Step-by-step explanation:
The correct answer is option 4) All of the above. Factors such as poor visibility, high traffic volume, and narrow roadways can greatly increase the probability of a struck-by-vehicle incident. When visibility is low, drivers may not be able to see workers or pedestrians, which increases the risk of accidents.
High traffic volume can lead to congestion and erratic driving behavior, further elevating the risk. Finally, narrow roadways can limit the maneuverability for vehicles and reduce reaction times for drivers to avoid collisions.
The use of spotters, parabolic mirrors, and cameras can help mitigate these risks by improving the visibility of workers and providing a larger field of vision around vehicles or construction zones.
Installing appropriate controls such as traffic signals can also be crucial in circumstances where there have been frequent accidents or incidents, especially those resulting in loss of life.
