Max Marks: 80

Answer any FIVE Questions :
All Questions carry equal marks :
1. (a) Discuss about the air pollution caused by road traffic and the measures that can be employed to reduce the same.
(b) How the changes in vehicle design and change in the road surface can reduce the traffic noise? Explain. [8+8]

2. Define the terms: traffic volume, speed and density and basic capacity and practical Capacity. Discuss the importance of the parameters. [16]
3. What are the causes of road accidents? Explain in detail. [16]

4. Explain the procedure involved for assessment of parking demand in view of land use and parking generation rates. [16]
5. (a) Discuss about the need for speed regulation and the general principles governing the application of speed limits.

(b) What are the types of regulations normally imposed on traffic? Explain. [8+8]
6. What are the automatic methods of organizing spot speed studies? Explain any one method in detail manner. [16]

7. How do you plan fly-overs and other bridges in urban context in connection with the capacity? What are the other factors generally considered for planning of yovers and expansions of structures? [16]

8. Explain how the following information can be given to the drivers through road markings
(a) On a two way road section, overtaking is permitted in one direction; but not permitted in the opposite direction.

(b) At an intersection, no vehicle is permitted to either park or to stop even for
A short time also Give colours of markings used and specifications in each case. Support your answer with neat sketches. [16]

Code No: 07A70106
R07 Set No. 4
1. Explain various types of parking surveys. How do you conduct parking space Inventory, draw some figure layouts? [16]

2. (a) How are the speed studies presented?
(b) What are the various objectives and application of spot speed studies? How spot speed studies are are carried out? [8+8]

3. Explain the objectives of installing road traffic signs. What are the various types of traffic signs generally used for traffic control and road safety? Explain with suitable answers supported by neat sketches. [16]

4. (a) How are speed data collected.
(b) What are the characteristics of slow moving traffic in India? Also write the mean speeds and standard deviation of slow moving vehicles. [8+8]

5. Write short notes on the following:
(a) Collision diagram.
(b) Role of Speed in accident severity and need for Speed Control.
(c) Pedestrian safety.
(d) Traffic Management measures to reduce accidents. [16]

6. Increasing traffic in urban areas is a major cause of decreasing quality of urban life. How do you justify the statement? Discuss. [16]

7. A road consists of 4 lanes, 2 in each direction; the maximum capacity of 2 lanes in one direction is 1800 vehicles/hour. When vehicles are stationary in a jamming condition, the average length occupied by a vehicle is 6.00m.

During a period of observation, the actual volume of traffic in one direction is steady at the rate of 1000 vehicles /hour.

Find the time in seconds which elapses from the moment the signal turns red until the stationary queue reaches another intersection 100m from the signal. Assume a linear relationship between speed and density. [16]

8. Write short notes on the following:
(a) Speed Control by Traffic Islands.
(b) Optimum Cycle Time.
(c) Fixed Time Signal.
(d) Pedestrian Phase in a Traffic Signal.

Traffic Engineering Set 1 :
1. (a) Explain how the increased traffic in urban areas is becoming an environmental problem.
(b) Discuss about the measures to be taken to reduce the adverse effects of traffic on environment. [8+8]

2. Explain the level of service concept in Highway Capacity Manual 2000. Write the factors which may be considered in evaluation of level of service. [16]
3. Didifferentiate between manual counting traffic and Mechanical method of traffic counts with merits & demerits and suitability. Have do you present the volume data.
