GATE 2023 AR — Planning – Question 65

Urban Land Use and Transportation · Aggregate and disaggregate transport demand models and forecasting · 2 marks · Numerical answer

Daily household trip rates by household size 1, 2, 3+ are: zero vehicles 0.5, 2, 4; one vehicle 0.6, 2.5, 5; two or more vehicles 1, 3, 6. Corresponding household counts are zero vehicles 100, 200, 150; one vehicle 200, 300, 200; two or more vehicles 50, 100, 50. How many daily trips come from households with at least two people and at least one vehicle? Give an integer.

Show answer and explanation

Correct answer: 2350 to 2350

Explanation

Include only four cells satisfying both restrictions. One-vehicle households contribute 300×2.5+200×5=1750 trips. Two-or-more-vehicle households contribute 100×3+50×6=600. Total is 1750+600=2350 trips/day. Exclude every single-person and zero-vehicle household.
