To reduce urban congestion, the city council plans to charge a $10 daily toll for any vehicle entering the downtown district. The council expects this toll to encourage more residents to use public transit, which currently operates at only 60% of capacity.
Which of the following would be most useful to determine in evaluating the likelihood that the plan will achieve its goal?
- Whether most downtown-bound drivers live in areas with convenient access to existing public transit lines.
- Whether the toll is higher or lower than the cost of a daily parking pass downtown.
- Whether the toll revenue will be sufficient to fund future repairs to the city's subway system.
- Whether the council can guarantee that the toll will eliminate downtown congestion entirely within one year.
- Whether other cities that imposed similar tolls saw an increase in the number of bicycle commuters.
