The figures in the right hand margin indicate marks. Q1 a) b) c) d) e) f) g) h) i) j) A passenger car weighing 3 tones is required to accelerate at a rate of 3 m/sec2 in the first gear from a speed of 10 kmph. The gradient is +1 percent and the road has a black topped surface. The frontal projection area of the car is 2 m2. the car tyres have radius of 0.33 m. the rear axle gear ratio is 3.5:1 and transmission gear ratio is 2.5:1. Calculate the engine horse power needed and the speed of the engine. Coefficient of rolling resistance= 0.02 Coefficient of air resistance= 0.39 Tyre deformation factor λ = 0.935 (7) b) What are the object and scope of traffic engineering? Explain briefly. (3) a) Enumerate the different methods of charring out traffic volume studies. Indicate the principle of each What are the human factors governing road user behaviour? (7) b) 1 Q3 a) Page Q2 Answer the following questions: (2 x10) What is traffic rotary? What are the ill effects of parking? Differentiate between basic capacity and practical capacity. Draw the relationship between traffic density and traffic volume. Five spot speed observation were taken i.e.55, 45, 60, 54 and 75 kmph. Calculate Time mean speed and Space mean speed. What is thirteenth highest hourly traffic volume? What is trip generation? Define Jam density? Differentiate between home-base and non home-base trip Define Origin and Destination survey? (3)
