Test 2 Paper 1

Traffic 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 which category you willinclude section of University Road between NED University and NIPA chowrangi.

Q.2 What are different base conditions which usually do not prevail and therefore

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, 1.5miles in length. If the DDHV is

(4000+Your Roll No.) veh/hr with 10% trucks and 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 level of service C? Assume that base conditions of lane width and lateralclearance exist and that interchange density is less than 0.50 /mi. The PHF =0.82.

Also comment on the results as well.

Q.1 How would you differentiate between design analysis and operational analysis

within capacity analysis?

Q.2 Suppose you have performed a capacity analysis for a particular section of afreeway, whose free-flow speed was 80mph, and the result you have obtained is

LOS D. If authorities want to operate this facility at 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 on average 10 access points per mile along the segment

with 50% no passing zone, current traffic on the facility is (350+Your Roll No.) veh/hr

(total,both ways) including 15% trucks and 5%Rvs. The directional distribution is60/40 with PHF 0.92. For the current condition described, at what level of service

would the facility be operated in a direction of 60% traffic. Also comment on the

result as well.
