| description | <p>On-road traffic is a significant source of air pollutants. The spatial and temporal configuration of on-road emissions should be described with the best available information, to underpin the air quality management, or to undertake studies about the behavior of pollutants in the atmosphere. The emission maps are typically built using intensity maps and hourly traffic profiles. We present an updated map for the year 2013, of the daily intensity of traffic of the Distrito Metropolitano de Quito (DMQ) and its hourly variation by type of day, based on counting 335 points developed by the Secretary of Mobility from the Municipality of Quito. The roads with most traffic are located mainly in the north of the urban area of Quito and those that connect to the valleys of Los Chillos Cumbayá and Tumbaco. In the north, the traffic flow of working days is over Saturday flows (10%) and Sundays (60%). In the south, traffic flow on Saturdays is similar to the values of working days. On Sundays, the traffic intensity is reduced by 26%. In roads of the urban area of Quito the traffic is reduced during holidays. However, in the ways of the periphery there is an increase (between 11 and 47%) compared to the flow of the weekdays. In the future this information will be used to generate maps of high spatial and temporal resolution of the emissions of primary air pollutant. These maps will allow the performance of updated studies of air pollutants dispersion in the DMQ.</p> |
