QI/ A car travelling at a constant velocity of 30 km/hr,
see a man walking across the road (32m) ahead.The driver
reaction time is 0.2 sec. , and the brakes are capable of
production a deceleration of 1.2 m/sec ,Calculate the
distance from where the car stops to where the man
crossing.
Q2/ A truck with mass power ratio of 1200 kg/kw
travelling at a speed of 60 km/hr on a straight road of a
certain grade with a smooth pavement. Assume the weight
of truck is 1600 kg and the cross sectional area of the truck
is 4.5 m2 .Find the max. grade which can be climb by this
truck?
Q3/ Answer the following
1- Classify the rural highways ,indicate the design
speed in km/hr for each class.
2- What is the driver characteristics that effect their
driving performance.
