Question

Match the models in Group I with their corresponding applications in Group II.\[\begin{array}{|c|c|c|} \hline \textbf{Group I} & & \textbf{Group II} \\ \hline \text{(P)} & \text{Logit model} & \text{(1) Trip assignment} \\ \hline \text{(Q)} & \text{Greenshield model} & \text{(2) Modal split} \\ \hline \text{(R)} & \text{Gravity model} & \text{(3) Traffic flow} \\ \hline \text{(S)} & \text{Multiple regression model} & \text{(4) Trip generation} \\ \hline & & \text{(5) Trip distribution} \\ \hline \end{array}\]

• A. P-2, Q-1, R-5, S-4
• B. P-1, Q-5, R-2, S-3
• C. P-2, Q-3, R-5, S-4
• D. P-5, Q-3, R-4, S-2

Hint:

The Logit model is used in trip assignment, while the Gravity model helps in trip distribution. The Greenshield model is essential for traffic flow analysis, and Multiple regression is used for trip generation predictions.

Answer 1

The Correct Option is C

Step 1: Analyze the models and their applications.
- (P) Logit model: A model used for Trip assignment to allocate trips between origins and destinations. Therefore, the correct application is Trip assignment.
- (Q) Greenshield model: Primarily used to model traffic flow and vehicle speeds as a function of density. This aligns with Traffic flow.
- (R) Gravity model: This model is used for Trip distribution, where trips between zones are modeled based on the gravitational attraction between them, similar to how masses attract each other.
- (S) Multiple regression model: It is used for predicting Trip generation based on factors like land use, demographics, etc.

Step 2: Match the correct applications.
- P corresponds to Trip assignment (1).
- Q corresponds to Traffic flow (3).
- R corresponds to Trip distribution (5).
- S corresponds to Trip generation (4).

Final Answer: (C) P-2, Q-3, R-5, S-4
