Driving Restrictions that Work? Quito's Pico y Placa Program
RFF Academic Seminar
Arun Malik, George Washington University
Programs to reduce traffic congestion and air pollution by restricting use of motor vehicles on working days have generally not met with success, based on existing studies of such programs. We conduct the first study of Quito, Ecuador’s three-year-old Pico y Placa program and find that it has reduced ambient concentrations of carbon monoxide (CO), a pollutant primarily emitted by vehicles, by 9-11% during peak traffic hours. During an extended daytime period that encompasses hours when population exposure to air pollution is likely to be highest, CO concentrations have been reduced by approximately 6%. Given that ambient concentrations of CO generally track the spatial and temporal distributions of traffic, these reductions in pollution suggest similar reductions in vehicle flows.
