Tolling by Time Reduces Congestion and Improves Air Quality
September 24, 2010
Current solutions for traffic congestion on U.S. highways, including the construction of old-style toll roads, are ineffective and do little to address ancillary problems such as road maintenance. A better, more efficient solution is to implement congestion pricing, say John Merrifield, a professor of economics at the University of Texas at San Antonio and a senior fellow with the National Center for Policy Analysis, and H. Sterling Burnett, a senior fellow with the National Center for Policy Analysis.
Traffic congestion in the nation's 439 urban areas cost U.S. taxpayers $87.2 billion dollars in 2007, according to the Texas Transportation Institute. Consider:
- Approximately 2.8 billion gallons of fuel were wasted in 2007.
- The average travel time delay during peak periods was 35 hours per driver.
- The average cost per driver due to wasted time and fuel was $757.
Traditional toll roads and toll lanes are most often not operated in a way that helps reduce congestion, say Merrifield and Burnett. A better solution is congestion pricing, which charges fees that vary by time for use of the roadway -- higher fees during peak hours and lower or no fees during off-peak hours.
Experience shows congestion pricing works:
- A congestion fee on bridges and tunnels between New York and New Jersey resulted in a 7 percent decline in traffic during the peak morning period and a 4 percent decline in the peak evening period.
- Traffic declined 15 percent in both London and Stockholm under congestion pricing schemes.
- In Singapore, congestion pricing resulted in a 45 percent reduction in traffic.
