What is a primary function of computerized traffic models?

1. Analyze traffic signals

2. Test the impact of land use scenarios

3. Measure vehicle speeds

4. Estimate parking needs

The correct answer is: Test the impact of land use scenarios

A primary function of computerized traffic models is to test the impact of land use scenarios. These models are designed to simulate and analyze how different land use patterns and development proposals can affect traffic flow, congestion levels, and travel behavior. By inputting various scenarios, such as changes in zoning, building developments, or transportation infrastructure, planners can evaluate the potential impacts on transportation systems before implementation. This allows for informed decision-making and strategic planning in urban development. The other options, while relevant to traffic management and planning, do not typically represent the primary function of traffic models. Analyzing traffic signals, measuring vehicle speeds, and estimating parking needs are important, but they are more specific tasks that may utilize traffic models rather than being the fundamental purpose of such models. Traffic models are particularly useful for understanding the broader implications of land use changes on transportation systems.
