TEST 2- PAPER 1Test 2 Paper 1Traffic Engineering and Management Roll No.

Q.1 How would you differentiate between freeway, multilane highway and

two-lane two-way highway in the context of capacity analysis? In whichcategory you will include section of University Road between NEDUniversity and NIPA chowrangi.

Q.2 What are different base conditions which usually do not prevail andtherefore adjustments are made while performing capacity analysis?

Q.3 Define ATS and PTSF, What are their significances?Q.4 What are different strategies that reduce the exposure of road user

and hence helpful in reducing congestion and road accidents.Q.5 A long section of suburban freeway is to be designed on level terrain. A

level section of 5 miles is however, followed by a 5 % grade, 1.5milesin length. If the DDHV is (4000+Your Roll No.) veh/hr with 10% trucksand 3% RV’s, how many lanes will be needed on the a) upgrade, b)

downgrade, and c) level terrain section to provide for a minimum levelof service C? Assume that base conditions of lane width and lateralclearance exist and that interchange density is less than 0.50 /mi. ThePHF =0.82. Also comment on the results as well.

TEST 2- PAPER 2Test 2 Paper 2Traffic Engineering and Management Roll No.

Q.1 How would you differentiate between design analysis and operationalanalysis within capacity analysis?

Q.2 Suppose you have performed a capacity analysis for a particularsection of a freeway, whose free-flow speed was 80mph, and the resultyou have obtained is LOS D. If authorities want to operate this facilityat LOS B, what measures you will suggests to them?

Q.3 What is Passenger car equivalent? On what factors it depends.Q.4 What are different measures you would suggest to transport Law

makers in order to reduce injury severity during accidents.Q.5 A class I two lane two way highway segment of 20 miles in rolling

terrain has a base free flow speed of 60mi/hr. it consist of 12’ lanes,and 4’ clear shoulder on each side of the roadway. There are onaverage 10 access points per mile along the segment with 50% nopassing zone, current traffic on the facility is (350+Your Roll No.)

veh/hr (total,both ways) including 15% trucks and 5%Rvs. Thedirectional distribution is 60/40 with PHF 0.92. For the current conditiondescribed, at what level of service would the facility be operated in adirection of 60% traffic. Also comment on the result as well.
