Highway Engineering Questions and Answers – Traffic Engineering Studies and Analysis
This set of Highway Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Traffic Engineering Studies and Analysis
1. What is the first objective of traffic volume studies?
a) To decide priority for improvement of roads
b) For geometric design
c) For computing roadway capacity
d) To plan traffic operation
Explanation: The first goal of traffic volume assessments is to determine which road improvements, such as road relaying, road widening, and other projects, should be prioritised.
2. Pedestrian data is used for planning __________
b) Sidewalks and cross-walks
Explanation: Sidewalks, crosswalks, subways, and foot-over bridges are all planned using pedestrian statistics.
3. Which of the following method is more accurate for traffic analysis?
a) Manual count
b) Automatic count
c) Average of manual and automatic
d) Past records
Explanation: Automatic counting is more accurate than manual counting because it is done by machine for 24 hours.
4. The outgoing and incoming traffic are counted at __________
a) Traffic intersections
c) Urban roads
d) Traffic symbols
Explanation: Because traffic crossroads are convenient to count, outgoing and arriving traffic are frequently counted there.
5. The traffic that is prepared based on 365 days of the year is called?
a) Yearly traffic
b) Annual average daily traffic
c) Average daily traffic
d) Average yearly traffic
Explanation: AADT, or annual average daily traffic, is the traffic that is calculated over the course of a year.
6. The charts showing the variation of the traffic is called __________
a) Traffic chart
b) Trend chart
c) Variation chart
d) Traffic flow maps
Explanation: Variation charts are graphs that show how traffic changes over the day, year, and season.
7. The traffic design in India is based on __________
a) 10th hourly volume
b) 20th hourly volume
c) 30th hourly volume
d) 45th hourly volume
Explanation: In India, traffic design is based on the 30th hourly volume, which is regarded as the peak factor.
8. The 5 minute count at a traffic junction is 15 find the hourly count?
Explanation: The hourly count = 15*12
9. If the traffic volume count on a road is 150 and daily factor is 1.1 and seasonal factor is 1.2 then ADT is __________
Explanation: ADT= Traffic volume*D.F*S.F
10. The ratio of seven day average for 24 hours and 24 hours count on any particular day is __________
a) Daily factor
b) Seasonal factor
c) Annual factor
d) Weekly factor
Explanation: A daily factor is the ratio of the seven-day average for 24 hours to the 24-hour count on any given day.
11. What is the first stage in traffic engineering studies?
a) Traffic volume studies
b) Spot speed studies
c) Speed and delay studies
d) Origin and destination studies
Explanation: Traffic volume studies, which are carried out to understand traffic characteristics, are the initial phase in traffic engineering studies.
12. The traffic volume is usually expressed in __________
Explanation: Because traffic in India is heterogeneous and there are many different types of cars, each vehicle is given the same unit, PCU, which stands for passenger car unit.
13. The number of vehicles that pass through a transverse line of road at a given time in a specified direction is called __________
a) Traffic studies
b) Traffic flow
c) Traffic origin
d) Traffic destination
Explanation: Traffic flow or traffic volume, represented in PCU, is the number of vehicles that travel across a transverse line of road at a given period in a particular direction.
14. HCV stands for __________
a) Heavy commercial vehicle
b) Heavy cash vehicle
c) Heavy consolidated vehicle
d) Hard commercial vehicle
Explanation: HCV stands for heavy commercial vehicle which includes trucks and buses.
15. The traffic flow is __________
c) Static and dynamic
d) May be static or dynamic
Explanation: The flow of traffic on the roads is dynamic, changing throughout the year, month, and season. It is also dependent on the time of day.
The application of engineering techniques to achieve the safe and efficient movement of people and products on roadways is known as traffic engineering. Engineering of highways. Planning for transportation. Planning for the city. Human factors engineering is the study of how people interact with each other. Parking studies form of traffic research determines total parking demand. People’s parking needs are determined using a variety of counting approaches. During the planning and design phases of a project, traffic studies give valuable information. These assessments can be used to estimate the effects of phased developments, whether traffic signals are required, and whether service and emergency vehicles can access the site properly.
