• Abstract:
  Suppose a government adds two lanes to a highway in both directions but then restricts access to those lanes. The lanes will be “managed”—open only to people in carpools, or to people in single-occupancy vehicles who pay a toll. The toll will vary in response to demand, with the goal of avoiding congestion and keeping vehicles moving. Will the total amount of driving in the region rise, fall, or not change? This question lacks an intuitive answer. On the one hand adding road capacity should induce more travel, causing the total amount of driving to rise. On the other hand, restricting access, especially via pricing, might reduce demand for these lanes. This could make driving fall. A third possibility is that these two countervailing forces (more supply and higher prices) will cancel each other out, leaving driving largely unchanged. There are intermediate possibilities as well. The fact that the new lanes are priced, for example, might make total driving rise, but rise by less than would be the case if the new lanes were free. This result, however, could depend on the mix of vehicles in the lanes: on how many are carpools, and how many are paying tolls.
