Question

Considering the following statements (P, Q, and R), select the correct option. (P) Prediction of travel demand depends on target year modal alternatives.
(Q) Prediction of travel demand depends on target year population.
(R) Prediction of travel demand depends on target year land use.

• A. Only P is correct
• B. Only P \& R are correct
• C. Only Q \& R are correct
• D. P, Q, and R are all correct

Hint:

Travel demand depends on the three pillars of planning: Population, Land use, and Transport modal alternatives. Always check all three while forecasting.

Answer 1

The Correct Option is D

Step 1: Influence of Modal Alternatives.
Travel demand forecasting accounts for various transport modes (e.g., private vehicles, public transit like buses and metro, and non-motorized options). The introduction of new modes or enhancements to public transportation in the target year will alter travel demand distribution. \[\Rightarrow \text{Hence, statement (P) is correct.}\]

Step 2: Impact of Population.
Projected population in the target year is the primary driver of travel demand. An increased population directly correlates with a higher number of trips and consequently, greater travel demand. \[\Rightarrow \text{Hence, statement (Q) is correct.}\]

Step 3: Effect of Land Use.
The distribution of land use (residential, commercial, industrial) significantly impacts trip generation and attraction. For instance, a higher concentration of commercial zones will result in more work-related trips. \[\Rightarrow \text{Hence, statement (R) is correct.}\] Therefore, all three factors P, Q, and R are influential in predicting travel demand. \[\boxed{\text{P, Q, and R are all correct}}\]
