Question
A-1. When judging on the distance of incoming vehicles (e.g. during passing on two-lane roads) which visual factor is utilized? a. Angular movement b. Dynamic visual acuity c. Depth perception d. Vergence e. None of the above Explanation: A-2. What are the factors that can impact driver behavior (mark all that apply): a. Age b. Use of alcohol c. Race d. Drugs/medications e. Talking on cellphones f. Gender g. Illness (e.g. drowsiness) h. All of the above Explanation: A-3. Which of the following is the primary objective of transportation and traffic engineering? a. Speed b. Environmental friendliness c. Traffic data d. Safety e. Convenience Explanation:Explanation / Answer
A-1 answer: (c) depth perception.
As depth perception refers to the visual ability to perceive the world in 3D and distance of an object.
A-2 Factors affecting driver's behavior are as under:
a) Age: yes
Due to increase in age power of perceiving things and visual power decreases thus reaction time of driver increases.
b) Use of alcohol: yes
Drinking alcohol decreases conscious of the driver thus he/she loses control.
c) Race: No
No difference is there when person of different race drives.
d) Drugs/medications: yes
Heavy dose of drugs disharm human health and driver can lose conscious.
e) Talking on cellphone: yes
It deviates the focus of driver from road thus can be dangerous and behaviour of driver changes.
f) Gender: no
Driving behaviour do not depends whether man or woman is driving.
g) Illness: yes
Driver's illness may lead drivers to lose control.
A-3 answer: (d) safety.
Primary roal of each and every engineer is to serve safety to users in their work. All projects and their outcomes are rearranged if any safety protocol is violated.
