American Institute of Certified Planners (AICP) Practice Exam

Which option best demonstrates a useful function of a computerized traffic model?

1. Test the impact on traffic of different land use scenarios.

2. Analyze the effectiveness of various physical improvements.

3. Determine the impact of future zoning amendments.

4. All of the above.

The correct answer is: All of the above.

A computerized traffic model serves multiple essential functions in urban planning and traffic management, which makes the selection of all options a valid choice. Firstly, the ability to test the impact on traffic of different land use scenarios is critical for planners in understanding how changes in zoning, development policies, or economic factors can influence traffic patterns. By simulating various land use scenarios, planners can predict how different developments may lead to increased traffic volumes, changes in congestion, and shifts in travel behavior. Furthermore, analyzing the effectiveness of various physical improvements, such as road expansions, traffic signal changes, or the addition of bike lanes helps planners assess the potential benefits of these improvements on the overall traffic flow and safety. Computerized models can provide quantitative data regarding improvements, allowing for informed decision-making and efficient allocation of resources. Lastly, computerized traffic models are valuable tools for determining the impact of future zoning amendments. As zoning regulations shape land use, they consequently affect travel demand and traffic conditions. By modeling these changes, planners can predict how amendments will influence the surrounding transportation network and community. By encompassing all these functions, a computerized traffic model becomes a comprehensive tool that supports planners in mitigating traffic issues and improving the overall efficiency of the transportation system.
