Discuss three possible solutions for reducing traffic congestion on freeways. Be sure to explain what effect each would have on the supply and/or demand for freeway space

1 ) Impose a toll to drive on the freeway. This would push up the price of driving on the freeway and the quantity demanded of freeway space would decline while the quantity supplied would remain constant (as a result of the vertical supply curve for freeway space). If the toll were placed at the point where the market is in equilibrium at the most congested times of day, the congestion problem would be eliminated. 2 ) Build more freeway space. This solution would shift the supply curve for freeway space (a vertical supply curve) to the right but would not shift the demand curve. 3 ) Promote carpools or give incentives for carpooling. If more drivers were ridesharing, the demand curve for freeway space would shift to the left while the supply curve would remain in its original position. 4 ) Improve public transportation. As with the use of carpools, an increase in public transportation ridership would shift the demand curve for freeway space to the left while the supply curve would remain in its original position.
