Ques 57 Transportation Engineering

A traffic survey conducted on a road yields an average daily traffic count of 5000 vehicles. The axle load distribution on the same road is given in the following table:

The design period of the road is 15 years, the yearly traffic growth rate is 7.5% and the load safety factor (LSF) is 1.3. If the vehicle damage factor (VDF) is calculated from the above data, the design traffic (in million standard axle load, MSA) is _______.


276.4 is the correct answer.


Ques 58 Transportation Engineering

The perception-reaction time for a vehicle travelling at 90 km/h, given the coefficient of longitudinal friction of 0.35 and the stopping sight distance of 170 m (assume g = 9.81 m/s2), is _______ seconds.


2.02 is the correct answer.


Ques 59 Transportation Engineering

The speed-density (u−k) relationship on a single lane road with unidirectional flow is u = 70 - 0.7k, where u is in km/hr and k is in veh/km. The capacity of the road (in veh/hr) is _______.
