Answer:
(B) long sections of flat, tangent roadway and gently curving alignment.
Explanation:
Transportation can be defined as a process which typically involves moving people, goods and services from location to another through the use of various transport means such as train, car, motorcycle, ship, boat, aeroplane, etc.
The individual saddled with the responsibility of controlling or piloting the direction of movement of a car is generally referred to as a driver.
Perception-reaction time, also known as perception response time (PRT) can be defined as the amount of time taken by a driver (road user) to recognize a potentially hazardous incident on the road to the time he or she takes to react appropriately such as applying the car brakes.
Generally, a driver is most likely to experience longer perception-reaction time due to fatigue when he or she is driving in long sections of flat, tangent roadway and gently curving alignment such as a bend.
