1. 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: The ratio of seven day average for 24 hours and 24 hours count on any particular day is called a daily factor.
2. The weaving manoeuvres is a type of __________
a) Merging
b) Diverging
c) Intersection
d) Crossing
Explanation: The weaving manoeuvre is a type of crossing manoeuvre as it involves crossing of traffic.
3. Which of the following does not affect traffic flow?
a) Vehicles travelling at speed
b) Length of the vehicle
c) Weather conditions
d) Geometric design
Explanation: Traffic flow does not depend on the length of the vehicle, as it is not related to the flow.
4. The speed at which the value of time headway is lowest represents the __________
a) Optimum speed
b) Maximum speed
c) Maximum headway
d) Minimum headway
Explanation: The speed at which the value of time headway is lowest represents the optimum speed.
5. In countries like USA and UAE, which of the regulation is followed?
a) Keep to left
b) Keep to right
c) Keep to middle
d) Follow intersection
Explanation: In countries like US and UAE, keep to right regulation is followed as they follow the left hand drive.
6. When the gap of the vehicle changes to a smaller lane then it is called __________
a) Lane change
b) Forced lane change
c) Simultaneous lane change
d) Voluntary lane change
Explanation: The gap of the vehicle changes to a smaller lane then it is called as forced lane change, as it forces a driver to shift to the smaller lane.
7. The vehicles per unit length at any instant of time is called as __________
a) Density
b) Jam density
c) Maximum density
d) Traffic flow
Explanation: At any instant of time, the vehicles per unit length are called as density, if traffic speed is zero then it is called jam density.
8. The distance between the two consecutive vehicles is called __________
a) Space headway
b) Time headway
c) Jam density
d) Traffic flow
Explanation: The distance between the two consecutive vehicles is called as space headway, and it is measured from head to head of the vehicle.
9. The maximum jam density occurs at __________
a) Zero speed
b) 15th percentile speed
c) 30th percentile speed
d) 98th percentile speed
Explanation: The maximum jam density occurs at zero speed, which indicates that there is no movement of vehicles and the density is maximum.
10. If the space headway is 7m, then the jam density in vehicle/km is __________
a) 142
b) 144
c) 145
d) 146
Explanation: Ki=1000/7
Ki=142 vehicles/km.
