Highway Engineering MCQs - Traffic Engineering Studies and Analysis

1.The traffic flow is __________
a) Static
b) Dynamic
c) Static and dynamic
d) May be static or dynamic

Explanation: The traffic flow on the roads is dynamic it changes with year, month and season. It also depends on time daily.

2. What is the first objective of traffic volume studies?
a) To decide priority for improvement of roads
b) For geometric design
d) To plan traffic operation

Explanation: The first objective of the traffic volume studies is to decide priority for improvement of roads like relaying of roads, widening of roads and other works.

3. Pedestrian data is used for planning __________
a) Highway
b) Sidewalks and cross-walks
c) Kerb
d) Camber

Explanation: The pedestrian data is used for planning of sidewalks, cross walks, subways and foot-over bridges.

4. 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: The automatic count is more accurate as it is done for 24 hours by machine; it is more reliable than manual counting.

5. The outgoing and incoming traffic are counted at __________
a) Traffic intersections
b) Highway
d) Traffic symbols

Explanation: The outgoing and incoming traffic are usually counted at traffic intersections as they are convenient to count.

6. 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: The traffic that is prepared based on 365 days of the year is called as AADT or annual average daily traffic.

7. The charts showing the variation of the traffic is called __________
a) Traffic chart
b) Trend chart
c) Variation chart
d) Traffic flow maps

Explanation: The charts showing the variation of the traffic are called as variation charts which show the variation in day, time, year and season.

a) 10th hourly volume
b) 20th hourly volume
c) 30th hourly volume
d) 45th hourly volume

Explanation: In India the traffic design is based on 30th hourly volume which is considered as peak factor for traffic design.

9. The 5 minute count at a traffic junction is 15 find the hourly count?
a) 50
b) 100
c) 120
d) 180
