Which model is best for evaluating long-range urban transportation scenarios with land-use changes?

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

Answer: (A)

Evaluating long-range urban transportation scenarios with land-use changes requires a model that links regional land-use patterns to travel demand over time. A regional travel demand model does this by using land-use inputs to forecast trip generation, trip distribution, mode choice, and route assignment across a region. This framework is specifically designed for long-horizon planning and scenario analysis, allowing planners to assess how different land-use developments (more housing, jobs, density) and policy choices will alter travel demand and network performance. While activity-based models can capture detailed individual behavior and microsimulation models excel at operational details, they are either more data-intensive or focused on shorter-term or micro-level dynamics. Macroscopic flow models describe general traffic dynamics but lack explicit links to land-use change and long-range regional forecasting.
