A state transportation agency has proposed building a new toll road parallel to an existing free highway that suffers from severe congestion, arguing that some drivers will pay the toll to use the faster route, thereby reducing traffic volume and congestion on the free highway.
Which of the following would be most useful to determine in order to evaluate the agency's argument?
- Whether a sufficient number of drivers currently using the free highway would be willing to pay the proposed toll in exchange for a faster commute.
- How much the toll road will cost to construct.
- Whether the toll road will be built using the same paving material as the free highway, which could affect long-term maintenance costs but not driver willingness to pay.
- How many lanes the free highway currently has.
- Whether the state has built toll roads in other regions before.
