Time: 3 Hours}
[Max. Marks: 100
(10 :30 A.M. to 1:30P.M.)
Instructions : (1) Figures to right indicate full marks.
(2) Answer to two sections should be written in separate answer books.
(3) Use of programmable calculators is prohibited.
(4) Draw neat sketches and assumes suitable data wherever necessary.
SECTION -1
1. (a) Describe the basic steps involved in Urban Transportation Planning with a flow
diagram. 18
(b) Describe various goals and objectives to be achieved through transportation planning.
(c) Frame the guidelines for
(i) fixing boundary of study area
(ii) dividing study area into zones
(i) Home interview survey
(ii) Buses as a Mass Transit System
(iii) Sample size for O-D survey
(iv) Present state of art of co-ordination in India.
(v) Centroid of zone, cordon line and screen line.
(vi) Distinguish between Railway and Roadway.
4. (a) Explain how to find the initial G.F. of a Zone. 18
(b) Explain the significance of trip generation. Also discuss the factors which govern the trip production and trip attraction.
(c) Compute the future inter zonal trips exchange by FRATAR model for the
5. (a) (i) Explain factors affecting the choice of travel mode. 16
(ii) Discuss the post-distribution model split analysis and its limitations and advantages.
Assuming the gravity model for trip distribution with = t~2 (where tt is the shortest travel) compute.
(i) The trip distribution among the zones.
(b) The trips produced and attracted by 3 zones and travel times (tt) in minutes are shown in figure below :
(ii) The two-way link volumes on each link.
OR
(a) The socio-economic data was collected from the 28 zones. Develop the trip generation equations:
Total household income = Z jc1 = 4800
Total household size = x2 = 210 Total household trips = S y = 257 IX* = 885,000, T,x22 = = 1718
I,x-[x2- 36100, JCjy = 44350 E x2y = 2105 & Z y2 = 2625
(b) There are 4 zones in the study area. Develop the future distribution of trips matrix for the following present trips.
