Abstract

English Abstract: Programs to reduce traffic congestion and air pollution by restricting use of motor vehicles on working days have generally not met with success, given existing studies of such programs. We conduct the first study of Quito, Ecuador's four‐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% to 11% during peak traffic hours. 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. We find no significant evidence that traffic has shifted to other times of the day or week, or to other locations.

French Abstract: Des restrictions au trafic automobile qui marchent : le programme Pico y Placa de Quito. Les programmes de réduction du trafic automobile et de la pollution de l'air via des restrictions sur l'usage des automobiles dans les jours ouvrables ont généralement échoué, selon les études disponibles. Les auteurs présentent la première étude du programme Pico y Placa de Quito en Equateur ‐ un programme mis en place au cours des dernières années. On montre qu'il a réduit la concentration ambiante de monoxide de carbone (un polluant émis surtout par les véhicules) de 9 à 11% durant les heures de trafic le plus intensif. Comme les mesures de concentrations ambiantes de monoxide de carbone sont reliées aux coordonnées spatiales et temporelles du trafic, ces réductions de pollution suggèrent des réductions correspondantes de flux de véhicules. Les auteurs n'ont aucune indication que le trafic a été déplacé vers d'autres plages horaires dans la journée ou la semaine ou vers d'autres lieux.
