For evaluating long-range transportation scenarios with land-use changes, which model type is most appropriate?

• A. Activity-based model
• B. Microsimulation
• C. Regional travel demand model
• D. Macroscopic flow model

Answer: (C)

For long-range planning with land-use changes, you need a model that links how people live and work with how they travel across a region. A regional travel demand model is built for exactly this purpose. It forecasts travel demand at the regional scale using inputs like population, households, employment, and land-use scenarios (zoning, development intensity, housing). It includes modules for trip generation, trip distribution, mode choice, and network assignment, so you can see how different land-use futures would drive changes in travel patterns and traffic across the regional network over a multi-decade horizon. This makes it the most appropriate tool for evaluating long-range scenarios that involve land-use changes.

While activity-based models focus on detailed individual activity sequences and microsimulation or macroscopic/flow models emphasize aggregated traffic flow, they’re less suited for the standard regional planning task of integrating land-use futures with regional travel demand over a long horizon.
