This indicator measures traffic volumes during the winter months as a proxy for carbon monoxide concentration levels. Carbon monoxide is a public health concern because elevated concentrations affect human and animal health by reducing the supply of oxygen to body tissues. Several factors can influence traffic volumes measured on Presidents’ Day weekend, including weather, economy, and availability of alternative modes of transportation. Current programs and policies such as transit-oriented development and increasing transit service look to reduce traffic volumes. Winter traffic volume is monitored by CalTrans on Highway 50 near Heavenly Village.
