# Traffic Engineering Questions and Answers – Capacity of Weaving Sections

This set of Traffic Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Capacity of Weaving Sections”.

1. Vehicles which doesn’t change lanes in the weaving section causes inconvenience in traffic stream?
a) True
b) False

Explanation: “Vehicles which doesn’t change lanes in the weaving section causes inconvenience in traffic stream” is an incorrect statement. The correct statement is, “Vehicles which change lanes in the weaving section causes inconvenience in traffic stream”. Hence weaving sections become the bottleneck of the road system.

2. What is weaving capacity?
a) The maximum number of vehicles per hour that can cross a weaving section in a period of time
b) The minimum number of vehicles per hour that can cross a weaving section in a period of time
c) The maximum number of vehicles per day that can cross a weaving section in a period of time
d) The minimum number of vehicles per day that can cross a weaving section in a period of time

Explanation: Weaving capacity is the maximum number of vehicles per hour that can cross a weaving section in a period of time. It is also defined as the no. of lane change operations within the given weaving section.

3. Weaving capacity is affected by which prime factor given below?
a) Length of weaving section
b) Driver characteristics
c) Traffic police
d) Traffic control devices

Explanation: Weaving capacity is affected by the length of the weaving section. In Type A configurations (in Highway Capacity Manual, 2000) there appears to be a great sensitivity to length and Type B and C sections show little difference in the capacity of the section.

4. Higher capacity value occurs when free-flow speeds are ______
a) Higher
b) Low
c) 30 kmph
d) 60 kmph

Explanation: According to Highway Capacity Manual (2000), Higher capacity value occurs when free-flow speeds are higher. Weaving capacity is affected by the length and width of the weaving section.
