(b) Explain with sketches transit routing problem. Discuss the main entities involved in transit
04
routing.
(c) The design year total person trips distributed between four zones A, B, C and D are shown
07
in the table below. The modal split analysis shows 25/75 for private car vs public transport
as an overall split. The peak period car occupancy is 2.5 persons per car and 50 persons per
bus. Develop the trip matrices for the two modes and total vehicular trips. If the goods
vehicles constitute at 20% of the person vehicle trips, calculate the total vehicle trips.

Q.7 (a) Briefly explain the Moore's algorithm for finding shortest path.
03
(b) On an urban corridor regular bus transit is operated with headway of 10 minutes during
04
peak hour. The reliability of transit arrival at a stop is observed 80%. If the seating capacity
of a bus is 50 and load factor 1.5. Calculate vehicle capacity of transit. If 50% schedule
operated during peak hour and double decker bus with seating capacity of 75 and load factor
is 1.25, what will be the change in passenger capacity?
(c) Explain with sketches various types of urban forms and structures. How these are affecting
07
transportation planning? Suggest the suitable mass transit systems for different urban
forms.
Q.8 (a) Briefly describe the following parameters used for transit system design: Headway,
03
Generalized cost, Vehicle capacity.

04
cycle and various actions. Suggest suitable ITS applications in TSM.
